Nov 28th
Here's Jupiter from the night of the 28th. There's a moon shadow near the limb. Jupiter season is winding to a close, not sure if I'll get any more good pics until next opposition!

Clearing off the Hard Drive
The Straight Wall and surroundings on the Moon
An old Jupiter taken with a wide field planetary camera. From Oct 14th.
The same setup, taken in UV light.
Tested out a different set of software for deep sky imaging, and took this pic of the Elephant's Trunk Nebula. Misread the histogram on the new software a vastly underexposed the image! Was able to salvage the above image however.
Here's a pic of the tiny storm that is believed to be the first sign of the return of the Southern Equatorial Belt. Taken Thursday night.

Not Jupiter - The Dumbbell Nebula (M27)
This is my first Jupiter-free update in a while. This pic is of a planetary nebula, a dying star, in the summer constellation Vulpecula. It's called the Dumbbell Nebula but I think it looks more like a Bowtie Nebula. It's object #27 on Messier's list.
I took this picture with my 100mm refractor, the color data is from an image I took a few years ago with my DSLR, and the brightness (luminosity) was captured last month with my ST-402, a highly sensitive monochrome camera. I combined the two images in Photoshop. You can click on the pic to get a slightly larger version.

Jupiter This Week
Lots of clear weather here in Cleveland this week, but seeing/atmospheric steadiness hasn't been good enough to get clear images of Jupiter. I pulled out the old mirror fan system and built a new one this week. The new fan arrangement really works well and I shouldn't need to tinker with it for a while.
Here are a couple pics of Jupiter, from Saturday night:
and from Tuesday night:
Interesting to see how the storm in the dark belt has changed over the course of a few days.

Big Jupiter
I have the new scope running very well now. The mirrors are collimated (aligned) pretty well now, the mirror still cools off really slowly but I installed some computer fans and I've figured out how to use them to best blow the tube currents out of the way while imaging. I also took a nice focuser off another scope and put it on the new one as an upgrade, added a motorized filter wheel, and am using an extension tube to squeeze out some more magnification. This pic is Jupiter & Co from Friday morning, taken in average conditions with clouds moving in and out of the area. Click on if for the full version!

New Scope
I have been setting up my new (used) scope this week. Here is a test pic from Thursday. The optics weren't aligned correctly yet, and the mirror hadn't cooled off, but I wanted to test out the tracking motors (they work!)
And here's an image from last night. Still getting some minor kinks worked out. Can't wait for Jupiter Season in the Fall!

Mars Mars Mars
I took this image on Tuesday night this week. (Click for a bigger version.) Sky conditions were very good. Mars is pretty small currently, but I managed to capture lots of detail on the small disk. The dark dot poking through the light clouds on the left is Olympus Mons, the solar system's largest volcano.

Clear Weather
The skies were clear in town on Saturday night so I got in some observing on the Orion Nebula despite the 12 deg temps. I used my new narrowband filter and it made the nebulosity much more noticeable, can't wait to try it on more objects. The seeing was pretty steady and I saw the 'F' star in the Trapezium for the first time.
Here's an image of the Trapezium I took last Winter.
