What exposure time to use for astrophotography is a recurrent question, especially with the waves of CMOS astrocameras now on the market. In this video, I answer this question, from my happy go lucky point of view! Well, that's how I roll, sorry for being lazy!
More seriously, as always, I may be wrong - so let me know in the comments how you determine your exposure time, and if you have any suggestions or if I made some glaring mistakes! This hobby is a continuous learning opportunity, that's one of the things that's great about it.
I am planning to have a video explaining shot noise and thermal noise as well and stacking - and stress the importance of SNR as what we are after!
