Exposure Calculator for RGB Stars for Dual Band Image
#4
Thank you both, that helps,  I was not sure what to pick or do with "spectral type and magnitude".

So after setting "Expose for" to Stars and entering in my settings and tweaking the exposure time to about 15 s I came up with

Faintest star: 15.4V
Stellar bloom magnitude: 9.4V
Brightest practical star (linear/not clipped): 9.8V


Other than going to the interactive atlas and clicking on the brighter stars, is there better way to know how many stars in a given FOV will be impacted by blooming and clipping so I can compare the impact of different exposure times?
