I finally got around to capturing some video clips of Jupiter.......unfortunately, seeing was only fair, and my small aperture scope [Celestron NexStar 4se] has to have above average seeing to enable me to use a barlow lens......to get a larger, more detailed image. As it is, I ended up with a wide field shot. It came out okay, but it was not what I was shooting for.
I would estimate that Jupiter never got higher than 20-25 degrees above the horizon.....not ideal for imaging. I would love to hear from any of you who have been able to observe the planet this year under good seeing conditions.
I did notice one major change from last year. The Great Red Spot has changed yet again. Last year is was a dark oval surrounded by a light outline. This year it is almost the opposite. Interesting.
I think I may try a new approach........put my webcam in my 12" Dob, and let the planet drift across the field of view. That should produce enough franes for Registax to work with. It will be difficult to line up and focus, but it's worth a try.
So without further chatter here is Jupiter with the Great Red Spot right of center, and from left to right, Ganymede, Io & Europa. The best 297 frames from approximately 1050 total frames. Optimized and stacked in Registax.
After reprocessing my barlowed video clips, this is the best image I have been able to come up with. The clip was captured just a few minutes after the non-barlowed image. The barlowed image illustrates the 'seeing' quality. Focus was as good a I could get it.
