My primary camera is a Canon EOS M mirrorless camera. I prefer this camera because not only is it more compact and less expensive than a full-blown DSLR, but the absence of a mirror means it doesn't suffer from the problem of "mirror shake" that affects DSLRs when making long exposures.
My secondary camera is a Canon EOS Rebel XSi, which was my father's before he passed away. It's older than the mirrorless, with fewer megapixels in the sensor, but still has capabilities the EOS M doesn't, such as taking fully continuous pictures, and using an optical viewfinder.
For video, I usually use a Sony HDR-CX240 Handycam, which was also my father's. All the other cameras are capable of shooting video, and the EOS M in particular is pretty good for it, but it's nice to have a dedicated video camera much of the time.
A compact point-and-shoot Nikon CoolPix L24 is almost always with me. It doesn't take the best pictures, but it's there for backup just in case I find a picture that has to be taken when the other cameras aren't with me.
This is undergoing considerable change, since most of these telescopes were also my father's, and are best used on the permanent pier mount in the backyard observatory, which of course I won't be bringing with me to England.
The one that is sure to accompany me is the small Meade 2045, a 4″/101.6 mm Schmidt-Cassegrain on a fairly unique equatorial mount, a little over 30 years old now, but still fairly capable in the right hands.
Among the others are a Meade 10″/254 mm Schmidt-Newtonian, Astro Tech 8″/203.2 mm Matsukov, Astro Tech 6″/152.4 mm Ritchey-Chretien, Celestron 8″ Schmidt-Cassegrain, and Astro Tech 80 mm apochromatic refractor. I'll describe these in more detail when I've decided which ones will be accompanying me, and what I'll be doing for a mount.
I use open source software wherever possible. I've been a big user and consumer, and sometimes contributor, of open source at least since my first Linux installation back in 1997.
The main exceptions to this are Registax and Deep Sky Stacker, two pieces of software that are uniquely made specifically for combining astrophotography images, and for which there really is no other substitute.
Other than those, my processing usually involves Digikam for overall picture management and light editing, Luminance HDR for, well, HDR images, Hugin for my vast panoramas, and the GIMP (GNU Image Manipulation Program) for more involved editing.
When it comes to video, my mainstay is Kdenlive (just don't make me try to pronounce it) for the editing, and then I usually use Handbrake to compress or compact the video into something easier for me to upload, and for YouTube, Vimeo, et al. to process on their end.
The website is entirely open-source. The server is the usual Apache HTTPD, with Gallery 3 running the gallery and store, with the prints handled by Fotomoto. The web pages outside of those are hand-editied in GNU Emacs.
