Yes, you do have to correct for variations in brightness caused by the atmosphere. In the images, along with the target star, you select multiple reference stars. Reference stars should be similar in brightness to the target star and not be a variable star. The software will use variations in the reference stars to correct the target star for variations in atmospheric conditions.

Ahh ok I see. Yes that makes a lot of sense I wasn’t aware of that capability. What software were you using for analysis? Just ASTAP or something more specialised?
