The Lunar eclipse from Burlington

I awoke early and packed the car for the trip to Binbrook.

Then i decided to try to observe the eclipse from Burlington.
Starting at about 5 am, the moon was very bright and half obscured by
the Earth's umbra. With my glasses on it was so bright i got double images
and a lot of glare.
As totality approached, it dimmed nicely until i could view it without
the glare. I forgot that due to the size of the earth, the umbra is large compared to the penumbra. Probably the earth's penumbra is about as wide as the moon, considering the geometry of a solar eclipse.

I quickly constructed my tripod and put my finder-scope on it,
equipped with a zoom eyepiece. The moon was setting fast behind
the houses and trees.
I was able to view the eclipsing moon clearly as totality approached, and
even managed to snap a few time exposures with my pocket camera.
Alas it came too fast for my DSI so that's going to have to get first light on another occasion.

I noticed Orion and the M45 overhead, and that the sky was starting to brighten for dawn.

The edge of the moon still illuminated was very bright and sharp,
but it also had a kind of shimmering nature to it, as if the
sharp edge of the moon against the sky was moving just a little,
like the surface of an ocean.
The time scale of the motions seemed to be 1-2 seconds, not the rapid
scintillation i am used to from stars.

The moon faded into low cloud just after totality, and i lost it,
but i did get a good impression of the rapid dimming towards the end.
I was surprised to note that even though it was all within the umbra, parts were still darker in the middle of the umbra. The moon lit by a circular
arc of sunsets from half the world made a nice sight.

A photo of the moon across the street, above houses, power lines and trees.

I put my pocket camera on my tripod and made this 4 second exposure near the start of totality.

Eclipse views

One of the nice things about eclipses is that no two are alike. This morning's lunar eclipse certainly had its own unique flavour.
I didn't have transportation to the alternate site to join our fellow intrepid observers, so I observed from my neighbourhood here in Dundas. The partial phases were high enough in the sky to see from my home. I have always thought that a scope is the best way to photograph an eclipse, but binoculars often give a better view, so I used my 15x70 binos for some lovely views. As the moon got lower I was surprised to encounter my next door neighbour outside at 4 in the morning and let him look through the binos too.
As the moon got lower I set off on foot to view totality from a nearby cemetery that has a hill. I had hoped that the elevation would give me a good vantage point but I quickly abandoned it due to some very poorly placed trees (no, the spookiness of being alone at night in a cemetery was not a factor. That's my story and I'm sticking to it!) I walked on to a park at the base of the hill (I love the leisurely pace of lunar eclipses that allow you to wander like this) and found a spot to view and take a few pictures from. The spot had already been found by another observer who was armed with Canon 15x30 image stabilized binoculars. We traded views through our binos and although I have always been impressed with the IS binos, the view of the dim eclipsed moon was greatly enhanced by the larger aperture of my good old 15x70 Oberwerks.
In the light of morning I had my third encounter of the day when walking home. A gentleman was out tending his garden and upon seeing me walking by with camera bag, binocular and tripod asked if I had observed the eclipse. We had a nice chat during which he explained that he had just bought a cheap department store telescope but had not assembled it yet. I offered tips, cautions and, of course, and invitation. He, along with the others that I met, was given info on the HAA and encouraged to come out to our very friendly club. Amateur astronomy and amateur astronomers are all around us. How nice to come upon some of them by chance.
I don't have one of these new fangled digital cameras, so you'll all just have to wait until I get my film developed to see my pictures. I hope that your eclipse was as good as mine.

Lunar Eclipse

Ok... yes I am crazy! I woke up really early with the intention of going into Binbrook... if it wasn't fogged in. At home it was perfectly clear until I drove out onto the road. Then a wall of fog hit. I called work (in Oakville) to see what the sky conditions were there and it was perfectly clear and fairly dry. So I decided to head in early so that I can set up in the parking lot. Turned out to be a great idea since I didn't have to rush anywhere for my 7 am shift. A few people came out and enjoyed the view and told me how nuts I was.

Update by Tim Harpur
I managed to image from my appartment balcony - it started clear - the middle was clouded - then ended clear again. I didn't bother to use my tracking GT mount - instead I just set up my on my camera tripod and used my 400mm telephoto lens. I made a short video of shots taken roughly every minute, but even reduced to 200x200 it is 1.36MB so I can't post it here (it has now been posted on the main page below the CSC) - instead, here are a couple single shots. (Note: Unlike Kerry's images which show nice detail of the redenned eclipsed area, my images only show the shadow over-taking the moon. I had kept my exposures to 1/60th of a second to avoid trailing as I wasn't using my tracking mount - I was just informed by Kerry that at these powers an untracked photo can be exposed for much longer - her shots are also untracked - but for 2 seconds. Good to know! I'll have to do some more tests with un-tracked imaging)

An Interesting and Remote Pair in Cepheus

Open cluster NGC6939 and galaxy NGC6946 imaged Thursday night from home with my 80mm scope.
20x3min+darks stacked in Deep Sky Stacker and processed in PS.

By KerryLH
Link to the widefield version gives you an idea of how small they are. http://www.weatherandsky.com/Astronomy/August2007/ngc6939_6946.jpg

While imaging I was enjoying more DSO hunting through the 15x70 celestron binoculars... I was really happy to see M33 which wasn't even that high in the sky.

That night I saw more meteors than on the peak day. Also noticed one that made an extremely bright flash. I wonder if this is the same one that Tim mentioned when he was up in Tobermory... We both noticed it at around the same time (around 12:30)

Have Scopes Will Travel

The HAA Traveling Road Show made two stops this past weekend and entertained would be amateur astronomers from Hamilton at the Parks Canada Discovery Centre (PCDC), and from Brantford at the Brantford Tourism Centre (BTC).
Friday night at the PCDC saw a crowd of about two dozen guests enjoy presentations on observing by Tim Philp, Glenn Muller, and Mike Spicer. Gusting winds outside made observing difficult, but not impossible, and Glenn, Mike, Steve G, and Kerry LH provided views of the Moon, Jupiter, M13 and Albireo.
The highlight of the evening was the bright overhead pass of the ISS and Space Shuttle combination.
On Saturday, a crowd of about thirty guests who had read Tim Philp's astro-column in the Brantford Expositor joined HAA members at the BTC to find out more about astronomy and the HAA. On the display table were information booklets and examples of Tim Harpur's beautiful astrophotography.

Tim P gave an informative presentation and Glenn spoke on the benefits of joining a club.

The weather was even less cooperative than Friday night but the Tekatch's, Don Pullen, and Glenn set up their scopes anyway for a Q&A session.

Thanks to all those members (mentioned or not) who showed up with their knowledge and equipment. Your efforts were appreciated by all who came out :)

Satellite Watching

Help me identify this object! I got home last night in time to go out and watch the International Space Station and the shuttle go past, and stayed outside afterwards with my binoculars for some observing. The ISS/shuttle configuration was dazzlingly bright at about mag.-4 and right on time (of course!) passing nearly overhead at 9:57pm, but then 6 minutes later another satellite of about magnitude -2 (best guess) went by, following a nearly identical inclination. It started in the NE and traveled up towards the summer triangle but passed just NE of Deneb, when it faded as it passed into the Earth's shadow. So what was it? I don't know. Although there are lots of things flying around up there, I cant figure out what else could have appeared so bright. It was not in the same orbit as the ISS (during the 6 minutes since the station passed, the Earth turned to the east so any object following in the same orbit should appear west of preceeding object, right?). Suggestions are more than welcome. And yes, the rest of the night was lovely, with many object appearing beautifully in my binos and even Jupiter's moons showing very nicely. There are more opportunities for you to see the ISS and shuttle tonight and a lovely overhead pass tomorrow night. Check heavens-above.com for times and maps.

Milkyway Collage

So I spent 4 late hours imaging the Milkyway using an 18mm-125mm zoom set to 30mm f/4 - 6 frames - each frame is a set of 3 x 10 minutes at ISO 400 stacked. Then spent 2 days rotating, stitching, blending, colour balancing.... to get the following image (reduced to less than 2% original size):

Personally, unless printing large scale, I prefer the single frame 10 minute exposure using my 10mm-20mm ultra-wide zoom set to 10mm f/4 (image posted a few days ago) - it looks as good on small scale, no blend lines, and saves quite a bit of time.

Images and Thoughts from Starfest, by Bob Christmas

During this year's (2007's) Starfest, we were very fortunate to have gotten clear skies for two nights, and part of a third night, during our stay at The River Place.

The only rain was a few minutes of sprinkles Thursday morning.

IMHO, I'm not a huge fan of tenting, but the spectacular clear skies on the Wednesday and Friday nights, and excellent cameraderie amongst fellow astronomers and fellow club members, not to mention a gazillion Perseid meteors, including a few bright bolides, made the camping part of it well worth it.

Here are more images from Starfest that I took from two of the clear nights. I will post larger versions of these and other images soon:

The Lagoon Nebula (M8) in Sagittarius, from the Wednesday night (August 8, 2007):

The Andromeda Galaxy (M31), as well as its two dwarf-elliptical companions M110 (above) and M32 (below), from the Friday night (August 10, 2007):

When it was all over, on Sunday Morning, it was time to pack it in. Some of us, including a fellow HAA colleague whose tent here says it all, had our work cut out for us, taking everything down and packing it away.

But we all managed to get packed before an approaching cold front from the west brought in rain Sunday afternoon (...what timing!).

Ad Astra!

Images from Starfest

Starfest gave a number of clear skies - no rain (at least it hadn't hit yet when I packed up and left at 8:00am Sunday morning). A number of us spent Friday night imaging into the wee hours - and then casual observing on Saturday night - walking around and checking out the other equipment - it was quite a pleasure looking through a 25" telescope! A few very brilliant meteors were spotted - one that lasted about 3 seconds as it flashed and pieces broke off was a treat.

I'm up in Tobermory for a little more observing - tonight's forcast for the meteor shower is very promising here.

Report from HAA Group at Starfest

CLEAR SKIES (and so far NO rain)

Greetings from HAA's Active (pre-registered) members at Starfest: Today's beautiful skies will be followed by a grand night of observing (we hope - see the attached CSC). We've had one great night already - Wednesday was phenomenal with Kerry and Bob getting some nice images, Glenn and Gail getting the last object needed to complete their Messier list (M74), and Steve Germann discovering faint galaxies like NGC 404.
The most moisture we've had was the heavy dew on Wednesday night but we know how to cope and didn't have to pack it in until 2:30am.
According to Alex Tekatch, Starfest is the most wonderful time of the year.
That's all for now - stay tuned - your fellow observing members: Alex, Tim H., Ann, Bill, Anthony, Steve, Kerry, Glenn, Gail, Bob, Mike J., Cindy, Stewart, Jackie, Jim, Doug B., Doug W., Marg & Bruce.

PS, did we mention there is no sign of rain...

Currently we are expecting good sky conditions through the weekend!!!!!

Update by Bob Christmas
I arrived at Starfest on Wednesday afternoon (August 8, 2007), about 2-ish. I had my digital imaging setup ready to go at dusk that night, and, here's one of my results from Wednesday night (2007/08/08). This is the Trifid Nebula (M20), as well as open cluster M21 above it. -- Photo by Bob Christmas

Grimsby Observing: Friday and Saturday Night

*FRIDAY NIGHT*

What a fantastic 2 nights for observing and astrophotography. After the cold front went through Friday evening the skies became crystal clear. I wasn't able to join the gang in Binbrook so I had to do my observing from the driveway. Since Glenn and Gail live a very short distance away, they opted to keep me company rather than make the long trek out to Binbrook. While my telescope, camera and computer were doing all the work of imaging, I was enjoying the views of many deep sky objects through their 6in dob, and both my 15x70 and their 10x50 binoculars.

Viewed objects: (list provided by Glenn)
-31 Cygni - small blue and gold double stars
-NGC 6940 - open cluster in Cygnus
-M27 - Dumbbell Nebula
-M71 - open cluster in Sagitta
-NGC 6934 - small globular in Delphinus
-NGC 7789 - the Magnificent Cluster - open cluster in Cassiopeia
-M13 & M92 - glob's in Hercules
-NGC 6210 - planetary in Hercules
-Albireo - blue and gold double stars
-NGC 6543 - "Cat's Eye" planetary in Draco
-tons of satellites

*SATURDAY NIGHT*

Another great night. I'm surprised that I'm not burned out yet. Anyway while hubby was doing some radio dxing I decided to set up again on the driveway. Another beautiful night!!!! I had problems with my images from Friday night so I decided to try my targets again. M51 and M71. In between exposures I was viewing many targets in my 15x70 Celestron Skymasters.

Viewed Objects in 15x70s:
-m27 dumbell nebula
-m71 glob cluster, in hazy air I was barely able to see this in the my 6in
-m81/82 a very nice pair to look at in binoculars
-m31 Andromeda Galaxy still pretty low in the sky
-m51 surprised I could see this
-m101 - again another surprise to find in binoculars
-various clusters and nebulas above Sagittarius
-various open clusters and doubles in Cygnus, Casseopia, and Lyra

Both nights I was able to make out mag 6 with averted vision at zenith.

Friday with the GWS and everything

By 8:30 the last stragglers were still packing up to leave the park.

I selected a location on the hill with a clear view to the south and west, and a good view to the east, and started unpacking. Having a proper wrench, i was able this time to deploy the equatorial platform. Lots of new gadgets to unpack and set up.

The GWS now has a shroud, expertly assembled by Ann. It's so fine.

The scope was almost perfectly aligned from last time, and took only a minor touch
on the knobs. I aligned it with the shroud on, no problem. The fully assembled scope on the platform is tall enough to require a 3 step ladder for the zenith. There's 3 little rubber feet under the base of the Lightbridge 16, and they sit on flat parts of the platform without extra work. I did not try the second axis this time. I might have to add another small pad under the base for it.

We had some new members observing, and they brought a fine refractor on a goto mount.
Even a few non-members brought their scopes and set up.

The equatorial platform is great. It makes finding objects so much easier, and they
just sit there. Since it's for 43 degrees and the latitude of Binbrook is
43.1 degrees, i just basically leveled it on its 4 feet and pointed the finder at Polaris, and it was ready to go. With a little help from my friends, i had the scope up on the platform and ticking away.

I took the time to assemble and adjust the camera holder. My pocket camera
has auto-focus, and getting it to stop trying was not easy.
I snapped this photo of Jupiter and its moons... (upload will have to wait till i resize the photo)

A tour of the skies with the GWS was in order. I found the following: Jupiter, M57, M13, Mizar and Alcor.

Then on to fainter things...
M31, M92, M27, M70, M29, M54.

I tried the ring nebula with a 5mm lens and a Barlow, making it fill over half
the field of view in the eyepiece.
Th platform kept me on target, as i tried to focus it.

At that magnification, there was blurring of the stars to small blobs, and i think it's because the focal length is short (and the eyepiece has to be very fancy to cope). I will continue to search for eyepieces up to the task. There was no problem with brightness though. The ring was plain as day even at 731 times magnification.

I tried a camera holder Mike lent me, but it causes the scope to tip forward,
even with the clutch tightened down. I finally need a counterweight.
Jackie sold me her 3 inch scope an diagonal to use as a finder-scope.
Attaching the rings is my next project.
I noticed there's a place on it to put a smaller finder-scope.

The GWS is so big... :)

After about an hour, i noticed that objects were drifting out of the field of view. Strange, the platform had been working so well...
It had reached the end of its travel. 2 good things... it did not dump the scope,
and it took a few seconds to reset by simply grabbing the base of the scope,
lifting slightly and repositioning the platform at the other end of its travel
for another run.

The moon was big and red on the horizon. Smoke from Montana fires is adding to the redness. I pointed the scope at it. In spite of there being another scope, and my car,
in the light path, i still got the moon. It was bright enough once it cleared the car, to project an image onto a sheet of paper the size of a dinner plate. Bye bye night vision.

I bought a new stool to use, but spent very little time sitting.

I am now able to navigate the star charts much quicker, and brought in the dumbell nebula for the final item before packing up.

The dumbell nebula. My red dot is right on, and with a low power eyepiece i found it in seconds. I am so happy with my ability to find things in the sky.
The best part was that although everyone's scope had dewed up, the shroud on the GWS
kept it nice and dry to the end.

So i am happy, anyway.

Tuesday night report: Smokey Observing

Although the sky condition Tuesday night was not top notch, we still managed to get a decent amount of observing in. Not only were there the odd patches of high cloud... but much overlooked was a very thin layer of smoke aloft (from the Montana forest fires) which I noticed on the satellite imagery during the day, but was hoping it would not make it out this far. As mentioned in Steve's post I forgot my camera adapter so astrophotography was going to be out of the question. I ended up setting up my 80mm and 6in anyway but didn't really make much use of them compared to normal nights. Instead I spent some time testing out my new binoculars and checking out the views from Steve's 16in. I did make a few comparison views of m27 and m71 in my 6in and his 16in. Obviously it was not a contest :) With the 16in, M71, a faint globular cluster, was easily seen with direct vision in Steve's scope... and in my 6in, well lets just say it was barely detectable with averted vision. M27 was nice in both scopes. I'm sure in a darker sky with better conditions Steve's scope will perform even more spectacularly on those Messiers. Mike challenged me to find a faint band of stars that go through m27 in my 6in but I couldn't see anything until I took my cheap 1.25 diagonal off. It was a nice challenge... that also led me to realize how important a good quality diagonal is. Now turning my attention to the binoculars... They were a pair of Celestron 15x70 Sky Masters. I recently got them for my birthday and they are a replacement to my cheap and now broken 16x50s that I had since I was 11 years old. Anyway Jupiter and its moons were nice a sharp. The Milky Way was spectacular... I have to say this is where binoculars are a real treat to use. The tripod that Steve set up for me made viewing a little easier since they are a bit on the heavy side for the arms. With a little help from Mike I found a few Messiers including m27... which looked really nice, bright and condensed. It is pretty rewarding finding and seeing deep sky objects with out the use of a telescope.

Anyway that's it for now, I thought this was only going to be quick report.

BTW Keep your eyes on the moon tonight!! If it is clear in the east when it rises, you will notice that it will appear really red and will stay orange for quite some time. This is from all the forest fire smoke that is still high up in the atmosphere. The smoke should clear out in time for tomorrow nights observing which Mike just posted about.

Summer breeze and starry night

I arrived at Binbrook A to find Kerry, Tim, and Joe, several scopes, binoculars and computers all set up and ready to image. Unfortunately Kerry neglected to bring an important fitting and could not really image properly, so she decided to do some real time observing instead. The sun was just setting and it took a few minutes before Polaris could be seen.

I had my car fully packed with an EQ platform, and the GWS. I built a jig in the back seat so that the entire scope can now ride in the back leaving room for a passenger (or a tent) in the front, except for the EQ platform not quite fitting back there with the rest of it yet. (I plan to make some kind of wooden contraption to make it more compatible with the seat cushions)

Turns out for lack of a crescent wrench (the moon was near full, too) i could not test out my eq platform this time, but i did manage to unwrap it, power it up and align it and it did its job well, making almost no sound and moving ever so gradually. 4 knobs adjust the placement. I think the key is to use 3 of them to level and bring in the fourth for stability after it's level.

It's designed for 43 degrees north, which is about right on for Binbrook, so almost no shimming was needed. (I see that starfest is at about 44 degrees north). Alignment of the LB16 took only a few minutes, but i think some big knobs on the secondary adjustment screws would make things easier still. I also think i need to shim my laser aligner to get it perfectly centered. Another cool addition would be a right-angle finderscope. My red dot finder is great if i can see or estimate what i am aiming at, but not so good when there's light pollution making it hard to spot the fainter stars. Another option is to attach the laser to my binoculars, and use it to point the way for the GWS to follow.

Mike, Tim and Therese arrived presently and mike provided us with some fine advice. He also helped me fish up M71 and M27. Alas the camera holder eludes me once again and i did not get a chance to see my pocket camera sneak photos through the eyepiece yet. With averted vision some of the stars in M71 could be detected. I set up by Bino parallelogram and suffered a hockey-tape malfunction but it still served its purpose for Kerry's new binoculars. I tried some high power views using a 7.5 mm eyepiece to bring in Alcor and Mizar. They don't even fit in the same field of view, but the scope split the double nicely. The double-double was not split under 26 mm, and when i tried the higher power, the clouds were rolling in and i could not fish it up.

The clouds rolled in for good by 11:30 and i was packed up and ready to leave by midnight. I think tomorrow i will try the dark skies where i did my messier marathon, near Lynden.
