I see. There are a lot of advantages to standardising the length of your subs otherwise you get this huge library of darks etc that becomes hard to maintain.

I usually only use a few different exposure lengths.

Tracking performance of your mount really determines how long you can go. Longer is usually better than shorter except in DSLRs. Narrowband needs longer to get past the noise.
