In theory you have reduced the noise by a factor of 42 -
so you were able to capture a mag 11 target under city lights.

Thanks Allan yep certainly a bit of work involved but really happy with the result. Single subs did show a fuzzy blob, but yeah I think to get any fine detail through the noise from my location I've gotta go north of 20hrs.
I mentioned to Steve below, I've got a method to handle projects with lots and lots of data which involves splitting my sessions into smaller data sets and stacking each individual set first, before a final stack of all the set together for processing. APP weights every sub and prioritises the best data for the final stack. I think that the result is cleaner and better resolution, even though it may not be quite as deep, as effectively I'm allowing APP to reduce the contribution from poorer data sets.
