My first attempt at Orion with the 80D. Sometimes my exposure is slightly too long and there is a bit of trailing and stars become oval. In this case movement was from bottom right to top left. What is a good method for deconvolution?
Nice first shot! No tracker? I have an 80D and a 70-200, but I was convinced I would have to use a tracker.
If you didn't use a tracker, I may have to consider my 80D + the Samyang 85mm 1.2 (when it becomes available, if coma is low, etc., etc.) for intermediate sky astro.
If you have a tracker then you don't have to shoot hundreds of exposures (so less wear and tear) and less processing time. Also when you track you will capture more faint details than possible with multiple short exposures. What happens with multiple short exposures is that the faint subjects will not supply enough light to raise them above the noise floor, so they will be averaged out in the stacking process. At least that is how I understand things.
If you can afford (or have the ingenuity and time to build) a tracking system then it will be incredibly beneficial.
