I got 15 hours on the Statue of Liberty Nebula. I was even able to crop it a bit thanks to the 103 apo aperture and low noise of the Mono 533. I don't think adding anymore data will add much because the target is bright enough for my set up.
For some reason i cant attach and upload here so here is the link
