I read your post with great interest. What is the faintest magnitude that you can go to?

Thanks Greg
I can realistically get a good SN with 120 mins of exposure down to about 14.5
Anything dimmer than that gets a bit hard to find and the noise is high. I could still identify Ha emission below this but not much else.
