The first try of Jupiter photo with my 3X Barlow lens. Rather bad seeing didn't allow me to capture more details. I switched motor drive off to suppress vibrations during capturing.

It is interesting to see the changes in Jupiter's atmosphere during last year - the thin band in the North hemisphere (visible year ago) is not visible now.

Processing:
1. Stacked in K3CCDTools
2. Gamma 0.8, histogram adjustment in K3CCDTools
3. Unsharp mask in K3CCDTools (4, 0, 300)
4. Resized to 66% in Corel PhotoPaint, unsharp mask (in green color plate)
5. Color saturation enhancement in Corel PhotoPaint

Look here at AVI sample of best 25 frames of Jupiter.
Look also at comparison of processing results of K3CCDTools and Registax.

Processing: K3CCDTools + Maxim DL Demo + Corel PhotoPaint

A few minutes later... Stacked 400 frames in X2 mode in K3CCDTools. The motor drive was switched on. Stacking more frames than in the above case results in less noise, but also less details are visible.

Processing:
1. Stacked 400 frames in K3CCDTools (X2 mode)
2. Gamma 0.8, histogram adjustment in K3CCDTools
3. Unsharp mask in K3CCDTools (8, 0, 450)
4. Resized to 50% in Corel PhotoPaint
5. Realigning color planes and enhanced color saturation (150%) in Maxim DL Demo
6. Resized to 66% in Corel PhotoPaint
7. Unsharp mask (1, 0, 100) in K3CCDTools

Jupiter rotation + Io eclipse. 8.3.2002, 22:36-23:47 (8.3.2002, 22:36-23:47 UT)

In the second picture, the shadow of Io is just touching the left side of Jupiter's disk.
In the fifth picture, Io is just leaving Jupiter's disk.
The transit of Io in front of Jupiter's disk is not visible (low contrast).

Compare with Starry Night Backyard simulation (it is visible, that real phenomenon ran about 2 minutes ahead):

This photo is not a composition of multiply images nor mosaic, it is one exposure settings. I set exposure level in K3CCDTools to level, in which Jupiter disk was not saturated, but moons were visible.

This was the first clear night after 3 weeks! The evening looked promissing, but when my telescope was cooled down, huge clouds appeared. I wanted to give up the imaging session, but I beheld Jupiter by naked eye through the clouds. As I didn't watch the sky for 3 weeks, I wanted to see Jupiter notwithstanding that clouds. I noticed, that Jupiter image in telescope was much more stable than in my previous observing sessions. So I decided to get some photo through the clouds. After focusing the image I found out, that clouds were going away, so I waited a little bit. And result is here!
