The question often arrises from the above of what piece of software to use for stacking and processing the resulting images that you take using your camera. Or, also often the case, people don't realise that there is software available to make this easy. So here I am going to list a few options, hopefully making it easier for anyone who finds this page.
Deep Sky Stacking Programs for Digital SLR Cameras
A common aproach to astrophotography has become the use of Digital SLR cameras (DSLR). These are relatively cheap, can be used for astronomy and ordinary terrestrial photography, and produce surprisingly good astronomy images so have become quite popular.
There's a few basic steps required for getting started in DSLR astrophotography. I would summarise them as:
1. Buy a camera
2. Buy a tripod, telescope or other tracking platform
3. Acuqire a piece of software to help take long exposure photographs
4. Acquire a piece of software to process (including stack) the photographs you take.

If you know of programs which are suitable for DSLR astrophotography image processing that are not on this list please let me know, also let me know if information here needs updating. Thankyou.
Software suitable for stacking and/or processing astrophotography DSLR images:
1. RegiStar
This is a fantastic piece of software for aligning and combining individal astrophotographs from digital SLR cameras. It works very efficiently with large files, is amazingly capable in aligning photographs and has quite good stacking algorithms built in as a bonus.
This software is primarily intended for simply the registering (aligning) of frames such that they can be combined. This piece of software is so good that you can combine old film images with new digital images, or digital images from different cameras with differnt focal lengths and all sorts. It will also easily handles field rotation (fixed tripod shots are OK) and pretty much any other distortion.
The only down side I have found to this software is that it does not read Canon RAW files, so conversion to some other format such as TIF is required first.
Unfortunately excellence comes with a price, and in this case that's about US$159.
The version of RegiStar that I am familiar with is 1.0.

2. Deep Sky Stacker
This is a free and very capable piece of software for aligning, combining and performing post processing of astrophotographs from digital SLR cameras. The best thing about this software is that it's free, and amazingly capable for something that is free.
This software will read a very wide variety of file formats including Canon RAW format, and process them. I have had some issues with processing canon RAW files so typically choose to first convert the RAW files to TIF before processing. This may simply be a lack of experience on my part, as I do not use this software often.
From my limited experience with Deep Sky Stacker I have found the aligning and combining of images to be quite efficient but the processing of a stacked image to be relatively resource intensive and slow. As a result I quickly settled on using Deep Sky Stacker for the aligning and stacking of frames then saving the file and working with it in PhotoShop instead.

3. ImagePlus
I cannot say much about ImagePlus as I have not used it for DSLR image processing. However many people do and it comes highly recommended. You can find out plenty of information about it around the web.

4. MaximDSLR
Again, I cannot say much about MaximDSLR as I have not used it at all. However it is reported to provide the complete DSLR astrophotography solution from focusing to image acquisition, aligning, stacking and processing.

5. CCDStack
CCDStacker is one of a suit of products made by ? aligned to advanced usage of telescopes. I find their product range very interesting and capable but unfortunately priced out of my range.
