However, the long exposure will be more affected by sky glow and noise issues with the sensor. Actually it does make sense.

You’re welcome Gordy.
The fact is that there is a seemingly endless number of considerations as to what length subs you take and subsequently the total intergration time you use. There are plenty of guides available to give you a good starting point but from there you will learn what works best with your equipment and also ideal settings to use for certain objects ( some of which will exceed either your equipment or environment) I won’t fill up this space with all of the contributing factors because there are so many to list but also each has a discussion attached as to why various factors have certain effects. I am happy to answer some questions if you have any and would like to PM me.
Cheers
Ryan
