Thumbs up Final and best Jupiters from last night! 25/05/2006

Hi all.

Here's the final processed images from a great night last night. I started quite early, around 8:50pm and finished around 10:00pm when the seeing started to deteriorate.

In that time I captured 7 "normal size" avi's and 2 avi's at the large size with the extension tube.

I capture all avi's at 5fps, 1/25s exposure, gain around 30% and gamma 50%. Each avi was about 2 minutes long, some 2:20s.

Normal processing, split RGB, process each channel, 150 frames of each channel stacked, followed by LR 7x1.4 in AstraImage. Ganymede was aligned and stacked separately (each channel as well), and composited onto the final image in Photoshop.

Here's an animation of the 7 avi's I captured, all except 2 were very good quality and it was hard to choose the best one to reprocess bigger. Unfortunately it lost some quality when converted to gif, but you'll get the idea.

Jupiter + Ganymede animation (270k gif)

There are 4 images below:

1. Normal image with 5x powermate, normal processing.
2. Image with 5x powermate, resampled 150%
3. Image with 5x powermate + extension tube (from avi 1)
4. Same as above, but from avi 2 (slightly different processing, too).

I'm really, really happy with these. Especially the detail in the belts and on ganymede. The only thing i'm not pleased about, is that it's not going to be fun to image again is less than ideal seeing!

Comments welcome
