You don't even need a tracker at all. Just take a series of 20-second exposures, align them in hugin, and stack them. I have managed to get some remarkably good results this way, because the fact that the star background moves allows you to cancel out a lot of the noise that the camera and light pollution produces.
- gus_massa 10y agoIf the aligning phase can be automated, this looks like a nice plugin for ImageJ/ImageMagick or even an online version in a web page. (You an monetize it with ads about telescopes or something.) (Bonus points for a deconvolution filter. (Is it useful here?))
- joshumax 10y agoTwo pieces of gratis software (DeepSkyStacker Live) and RegiStax already do something like this, as well as PixInsight and the venerable Maxim DL, among others.
