AstronomyUkraine Posted October 18, 2020 Share Posted October 18, 2020 All astrophotographers ask themselves the same question. "Have I taken enough data". We hear about diminishing returns on data aquired, but what is your criteria for saying enough is enough? There are formulas out there, but with so many different combinations of setups, I don't see how they can be applied.I tend to evalute background noise in determining whether I have enough data or not. My laptop controlling the mount is on my local network, so stacking as I'm imaging is quite easy. I don't live stack, but will start a quick stack after 30-5 minute frames in Pixinsight, then every subsequent 10 frames, comparing them as I go along. Once I see no improvement in signal, or noise, I stop.Personally, I have been guilty of taking too many frames, especially in Ha, but prefer to be on the safe side, and have too many than not enough. How do members evaluate when they have enough data? Time limits, noise evaluation, or if you live in the UK, grab what you can, when you can? ?
