Thanks for the feedback guys.
Lester, you're right, there's probably a tad too much green - I already changed the intensity of the green channel to 1.02 when recombining in AstraImage, could probably have reduced a bit more (1.05 or so).
Regarding MAP processing:
1. Open registax, drag red channel BMP's in.
2. I use a 128px alignment box and align on a feature in registax, for example Europa and its surrounds (the right hand side of the image)
3. Run through registax as normal (as per my tutorial), save as TIFF, something like "jup1-right.tif".
4. Close/Re-open registax, drag the SAME SET of BMP's in again
5. Choose 128px alignment window, and align on a different feature in registax, for example, the white ovals at the top (the top left of the image).
6. Run through registax as normal (as per my tutorial), save as TIFF, something like "jup1-top.tif".
7. Open the 2 files in photoshop. You can see that the sharpest part of each image is the area you set the alignment box in registax.
8. Use the rectangular marquee tool (with a 20px feather, for example), and select the sharp part of one of the images. Ctrl-C to copy it to clipboard.
9. Focus the other image, and press Ctrl-V to paste. You'll now have a new layer, with the sharp part of the other image as the new layer.
10. Use the Move tool to move that layer to line it up over the fuzzy part of the background layer. Use the "visible" eye, click on and off to work out when you're exactly aligned over the top.
11. Once it's aligned, flatten the image - so now you've got the sharpest parts of both images combined.
12. Save it as TIFF, and do whatever else you want to do to it (take it to astraimage, etc).
Hope that helps!
btw one thing I forgot to mention, I captured at 30fps, and stacked 450/1050 frames in each channel.
Thanks!
