Update: Here is a link to a short animation w/ Europa and Callisto



Got this one before the fog rolled in. Threw in a small extension to get a little bigger image.

Also got some images from earlier in the evening of the Europa transit, will get more processed after work today

Here are the earlier captures:

Can't believe that these are taken with C8 and SPC900NC.
Amazing.

I must say, C8 and a ToUcam... I started with a very similar set up 9 years ago. I never was able to obtain anything of this quaility. Good Job!

Great shots there zambonii! I haven't seen you hanging out in the DSLR section lately. Have you jumped into the planetary realm? Hope all is well.

Clear Skies,
Jason

Thanks all.

Ed: It's kinda funny when I think back on things. I never really took note of just what I was doing from one imaging session to another. When I first started, I would take the scope out on ANY clear night and never realized just how important seeing was. Then I tried to push the image scale as far as I could and crossed my fingers that I could get a good image.

I now know that seeing is king
Getting enough light on the camera chip is queen
Focus is the joker or something :).

I think I have gotten to the point where I know when the seeing is good or if I just have poor focus. And I know the setting limits of the camera. The smaller images above are at f/30, and the larger image is ~f/36. At F/36, I have to set the gain too high and the noise and artifacts creep in.

One of these days I am going to upgrade to a more sensitive chip and be able to get smoother images and maybe push things a bit further, but I really need to consolidate equipment before I do that :).

BTW...I think I have had the C8 for about 3 years now. I still haven't collimated the scope. I havent really done anything with the scope since I unboxed it :).

Jason: I guess it is more about going with what is working right now :). My 6" scope for imaging I am having problems with guiding. My CG-5 has sticky DEC, and I am too lazy to tear it apart and clean it. I also have a flexture issue that I haven't nailed down yet (I think it is tube flex in my 6" because everything seems solid).

I really want to sell the CG-5, 6" and 8"SE and replace it with a CGEM + AT8IN or similar to pull double duty as planetary + deep space.

I still have some deep space stuff from 4-5 months ago I still havent fully processed. I have about 200 .avis of jupiter from the past week that I still need to process also :). Its cloudy tonight and looks to be cloudy tomorrow night so I might have time to get through them all.

Here is a link to a short animation w/ Europa and Callisto

Still working on all of the other captures, but above is a link to a short animation right before the fog got really heavy. I had put an extension in to get the f/l a little longer.
