I had difficulty understanding "GAIN and OFFSET".
In France we say "EXPOSURE and CONTRAST" to regulate the gain it is necessary to make several picture with different times of poses, to make simple to regulate the GAIN to the highest being careful that the stars is not saturated, if not to lower a little and for OFFSET I do not touch.
We understand better using real acquisition software; I chose
ASTROPHOTOGRAPHYTOOL, it is really good and free.
The top stars seem oval, right ?
