From Doug Welch:

Folks,

There was a big flare at 15:22UT today! Be on guard for aurora in the
next couple of days!

BTW; this weekend is looking promising for Binbrook…

New images posted by Clyde Miller of The Moon, M82, M17, M5, Saturn, and Comet 73P can be seen here.

The moon will be full and close by, but tonight shortly after midnight Io?s shadow will start to transit. It is anticipated that the Great Red Spot (GRS) will also be starting to cross the face of Jupiter and the shadow should be on the eastern edge of the GRS in the opposite hemisphere.

By the time the GRS transits(reaches mid point) about 2:00 am, the shadow will be north of the western edge of the GRS with the moon Io itself about halfway through the GRS and in the same plane as the shadow. This will afford opportunities to compare the transit speeds of the moon and the planet features as well as offer some wonderful imaging and sketching opportunities.

Now, if we can just get the weather to co-operate.

Well, the clouds rolled in just after we arrived – then after about 1/2hr the wind did a 180 and the clouds rolled back out the way they came – and suddenly it was so bright I thought I should have brought a book to read by the moonlight.

I stayed with viewing planets, the moon, and star clusters – sky was too washed out for anything else. We got a chance to watch a moon rising from behind Jupiter (at first I thought it was just distortion – but it was too consistent and growing, so I called Mike over to look) and the rings of Saturn were reasonably clear too. Looking through Mike’s bino viewer at the craters and mountain ranges on the moon was also a treat – there were some interesting sites along the shadow line.

I only took a few images – mainly of Saturn and Jupiter. I have processed the Jupiter sequence and will get to the others later. Unfortunately I don’t have the mount for attaching my camera to a barlow yet so my images of planets tend to be lacking detail.

Taking Tim Harpur’s advice on focussing resulted in the best digital photos I’ve taken yet! It took some practice, but I managed to get decent images of the moon and Comet 73P last night from our backyard. I used my Canon G3 camera (an oldie but a goodie!) attached to a Scopetronix maxview adapter/eyepiece. For the comet, I used the camera’s longest shutter speed: 15 secs at f/2.0 and an ISO rating of 100 (my 400 rating causes too much noise in the images). Although the image is tiny, it isn’t bad for a first effort. (At least, that’s what I keep telling myself!) Because I took the image through the telescope’s star diagonal, the image is mirror-reversed.

I also took an image of the gibbous moon. I used the photo editing software to un-mirror-reverse the image and crop it, but that’s the only processing I’ve done.

These are not nearly as good as the images Tim Harpur has been taking with his Digital Rebel XT, but, hey, I gotta start somewhere!

There is a report of a possible nova in Cygnus. Previously 12th magnitude, this star has outburst to 8th magnitude in recent days. The good news is that you should be able to see it in binoculars; the bad news is there is no shortage of 8th magnitude stars in Cygnus. Still for the adventurous the relevant links are below.

Jupiter has been my favourite planet to observe ever since I had a pair of binoculars. After getting my first telescope, I started to observe transits and look for the Great Red Spot (GRS) as well as all the other events that can be seen on this planet. I caught the double shadow transit in progress the other night and was quite annoyed with myself that I had been caught unawares. To ensure this wouldn?t happen again, I entered all the Galilean moon transits as well as GRS transits for the month of April into my Outlook calendar.

When I switched the view in Outlook to monthly and scanned the entire month, I noticed a peculiar pattern. Early every Friday morning in April, Io and her shadow will be transiting Jupiter. Interesting in itself, but the extraordinary part is the GRS will be transiting or at least prominent on Jupiter during each of these events!

Io will be crossing the northern hemisphere for each and so will not cross the GRS but will still give lots of pretty photo-ops I am sure.

Just what the world needed; another reason not to go to work on Fridays!

Unfortunately, we couldn’t make it out to Binbrook on Sunday night, so my daughter Alex and I went out in the backyard about 7:00 pm to look at Saturn and whatever else we could find in the evening twilight. Alex was very helpful. The first thing she did was grab hold of the telescope and pull it around to point it up at the sky. Unfortunately, it had been in its “park” position! After I re-calibrated the GOTO system and patiently (!) explained to her that she should let the computer do the pointing on this telescope, we had a look at Saturn.

Alex is getting to be quite an experienced observer, but I realized last night that this was the first time she’s ever looked through our big scope. When she looked into the eyepiece, her eyes flew open in wonder and she exclaimed “Mom! That’s Saturn!”. Saturn was breathtaking at 350X – seeing was easily 8/10 – and even in the twilight, its moons were easy to spot. We spent quite some time together enjoying the view.

Next, we looked at Sirius and then Betelgeuse to compare their colours. Always a neat way to introduce stellar evolution to kids!

Whenever the telescope was slewing around, Alex would play a kind of hide and seek with it. Another stern lecture ensued. This time highlighting the differences between a telescope and playground equipment!

Alex was quite interested in M42 – the trapezium was blazing away in a subtle cloud of nebulosity. But she decided that the Beehive Cluster was very boring. It was time to pack it in and get ready for school/work the next day.

I didn’t think of it at the time, but it might be fun to help Alex work on her own Messier Certificate. I wonder if any other parents have experience doing observing projects with their kids?

Well, it was a nice night at Binbrook – a half dozen or so members showed up with a variety of scopes and binoculars. I did my usual and spent most of the evening imaging – I haven’t processed any of the shots yet, but having glanced at the images as I downloaded it would appear I have good shots of Andromeda Galaxy, the Leo Trio Galaxies (M65, M66, NGC3628), the Sombrero Galaxy, the Crab Nebula, and M3 (globular cluster). Once I’ve had time to process the images I will post them. Anyhow, it’s been a late night and I’ve got work tomorrow.

Update Monday March 27/06
I’ve processed the Leo Trio and they turned out well with all 3 galaxies in the field of view this time. I’ve started with the others and will post them to my gallery tonight. Andromeda, which was rather low on the Western (or North Western?) horizon, is seriously lacking contrast and in the end did not turn out to be a very good – only the core showed to an appreciable amount.
