Registax is the main amateur astrophotography stacking application. It's free too . There is another one, but I can't remeber what it's called.So i took 200 images of Saturn. The main issue is that these are 3072x2304 images and Saturn's disc is only some 70x70 pixels. Is there any software that could automatically center and crop the 200 images?
Sorry, misinterpreted your request. I don't know of ones that crop it. If Saturn is in *rougly* the same place in each image (ie, you can crop all images with the same cropping) then I'm sure that linux command line tools (imagemagik?) can do it, or DPP if you have a canon camera. You the crop may not be as tight as if it were a single image, but you may be able to crop 70% or so of each photo, that would help.I know, i have several stacking applications.
What I'm looking for is an application that crops photos, i don't need the 95% of each image.
Thanks. I've had the ISS on about half of the frames.Very nice capture McWgogs! I wish I had had an opportunity to spot the HTV before capture, but there were no sighting opportunities where I live. Great job getting it, especially with hand tracking.
