Hi,

I am trying to stack around 2400 subs of 10 seconds. The reason for so many short subs is that I am using an Alt-Az mount.

The problem I am facing is that when I reach the integration step it stops and requires around 1500GB free space which I don't have.

Is there a way work around to solve this problem?

Yes, you have to chop up the data in like 100-200 subs per integration (or as many as your system allows) and then in the end, integrate the integrations. 2400 subs is indeed a very high amount and would require a very big system to process all at once.

Thanks a lot for your help Vincent. I am just new to this software and astrophotography and appreciate your help.

So you mean I should run the process from 1 - 6 for each batch of subs (say 200 subs) and save the integration of each batch and then upload them to process 6 and integrate all?

Basically yes, you tak say 200, integrate them (integration result is saved to your working directory and with that many subs I would probably organize that a bit to another folder). Then at the end, you load the integrated results back in as lights and integrate them (without calibration data of course).
