First few captures of Jupiter from last night.
OK, technicals: Meade 8" Schmidt-Newtonian telescope: that's f4, 821mm in photography-speak. First shot is prime focus to a Philips SPC900 webcam, black and white. Second is with a 2X Barlow added, unadjusted colour.
They're both stacks of around 100 images each, aligned and stacked in Registax 6. I tried ALE but it kept rotating images so output was confused. I think there are options I can use to stop it doing that, but I'll have another go later.
First night out with the big scope this year. It's getting cold out at night now. Next up, a few hours of stacking and post-processing - might leave that until tomorrow.
I'd really like to take a chainsaw to nextdoor's tree, it's blocking my view of Orion - you can just see Betelgeuse and Bellatrix peeking over the top of it. I was wanting to image M42 tonight but it wasn't coming out from behind the tree for another few hours. A different site for the scope next time, I think.
This year I am making a gingerbread house. There is an element of competition involved.
Here is my first architectural model. I'm hoping this will be the world's first gingerbread hyperbolic paraboloid roof.

Neela came to visit, so we went to the beach. Peggy had a lot of fun. She dug some holes and ran up and down a dune.
Why yes, that is a tiny 90mm Skywatcher Mak mounted on a mahoosive Meade LXD55 mount. The Skywatcher came on a little EQ1 mount which is fine for eye observations but is too wobbly for photography. I've had this LXD55 (and the 10" OTA which goes with it) for a while but hadn't thought to do this. Had to hack the mount a bit, but it's OK.
Now just have to get my head around how to set up and use an AutoStar mount..
- Nikon D50 direct mount to telescope. Single exposure.
- Webcam, 100 frames stacked and processed.
- Nikon direct mount again, 2s single exposure.
