On the bottom i think, the two things on the top would be the radiators.

Here's Clavius Crater, a 5 image mosaic taken earlier this evening with a Meade electronic eyepiece and LX200.

*edit to change picture: redid the stack using the complete video stream instead of just cherry picking a few of the best frames.

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?

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.

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.

Me and my classmates recently took images of Saturn through a 70 cm telescope for our astronomy project, with a 4096x4096 cam. We haven't processed the pictures yet, but I'll post them when we're done.

Our professor suggested IRAF, but I haven't gotten around to learning it. It's a free program.

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.

Other than that, I don't know.

Took this one last night. The star-like object is Molniya-2 9, an old Soviet communications satellite in a highly elliptical orbit. It's only about 4 meters long and 1.5 meters in diameter, and it was exactly 18,000 km away during the 30 second exposure. The long streak is a star it was passing by as I tracked it. Hail probe!

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.

Thanks. I've had the ISS on about half of the frames.
tracking is quite easy with the scope lubed good.
Only the zenith is a killer on a Dobson
