This is a silly beginner question but here it goes. I ran into an issue the other night and am looking for some guidance from those more knowledgeable.
I spent a rare clear night to shoot over 8 hrs on M81/M82 a few weeks ago. Due to my light pollution and mount, I am limited to ~1min subs so I ended up with over 400 subs. I am using APP to stack and process.
My issue is, when i got to the integration step in APP, it required more free harddrive space than I have on my SSD (I have ~100Gb free) to integrate the whole 400 or so subs. In the end I was only able to integrate the best about 200 of my 400 subs. So...
1) Should I use the slower 1Tb HDD when stacking large numbers of subs.
2) Or should I "stack in batches". Can you stack 200 subs, then the other 200, then combine them somehow?
3) Should I do the astrophotography thing and throw $$ at this problem until it isn't a problem anymore? (new SSD)
4) Stick to 3hrs or so on a target.
5) Something else...
Thanks for your thoughts!
