Mars x 2

[gaa_ian]

Just a single shot as I am yet to venture into the world of image processing. There is a comet like artefact from the nearby moon (I presume)
Lots to learn in this area for me, having spent so many years as a visual observer. I welcome recommendations for software to use for image stacking.

DSS is working great for me
Few online videos how to use it
But really it's one of those suck it and see apps

From DSS to CS5 for finish

I second what Peter said; DSS is very widely used, and it's free. You can do some basic processing with it while you decide what more
competent processing software to get.
