Hi Michael. Yes I checked that. GIMP has had 16 bit support since 2008 with the introduction v2.6 - I think that info is out of date. I cant vouch for its suitability overall because its not been designed with astrophotography in mind, so it's missing a lot of tools - pity. I've been trialling various programs recently, on and off, but just starting the final module of a uni course, I don't really have time to get into it. Come August I will be relatively free.

I've added another image - it's a single 10 minute exposure taken with my double arm drive. I'm sure that GIMP was used to process it, but it could have been imageJ.
