After a bit of a hiatus due to a big project at work and the fact that my wife walked into my scope and broke off the LNT Module/smart finder I finally managed to get out and get a shot of Jupiter last week. It is easily my best Jupiter so far. I used my ETX-125 and DSI monochrome camera w/ Meade RGB filter set on a 2X barlow. I collected for two minutes in each color channel (about 200 frames). De-interlaced w/ image magick, hand selected and stacked with Envisage (2X scaling factor w/ Drizzle) for each color, Combined the colors in Meade Image Processing then aligned the colors in GIMP2, and added some unsharp mask.
If anyone has any pointers of how to capture more detail with this setup, I'd love to hear them.
Thanks

Wow that is impressive considering you were flipping through filters, etc.

There's a lot of detail in the image you have there. You could get more aggressive with the wavelet processing to bring it out. Here's what I did in just a minute or two:

With Jupiter now at less than 45 arc seconds, you have only about 120 seconds in total to capture Jupiter before its rotational effects begin to blurr the image. That gives you only 40 seconds each for an R, G, & B take. You have to work quickly. Even shorter if you take a luminance shot.
Drift time formula is: 0.5/([Pi]3.14 X [Jup Dia] 45)/590) = 2.1 min!
Using these integrations should reduce blurring.

Wow, I really had no idea that it turned so fast. I guess I'll have to move a little bit quicker in the future.
Thanks!
