How to Calculate the Correct ADU Target for Flats – Astronomy and Astrophotography A Step-by-Step Guide - Using the ToupTek SkyEye 62AM and SkyEye 24AC as Examples

New blog post: How do you calculate the correct ADU target for your flat frames?

The formula is simpler than you think: ADU Target = Offset + (Max ADU - Offset) x 0.50
