I am using the Mosaic builder in EKOS to create a 24-panel mosaic of M31 through a C11. I have to capture four more panels on the far right of the galaxy, but here is what I have so far - in luminance only. The level of tiny detail I am getting surpasses anything I could get with my smaller scope. Since I want to create a 40" or 60" print, at 300 DPI, I wanted to show the tiniest details possible. The image here is only 2,400 pixels across. The mosaic is already 10,000 and will be more after I add the final row of 4 panels to the far right. At this resolution, the fine star clusters look amazing - and the background is littered with dozens of more distant galaxies. It is gorgeous and I cant wait to capture the RGB and Ha subs!

Here is one H-Alpha panel that shows the level of detail I am getting on the fine H-Alpha nebula within M31.

WOW! This looks mighty impressive! Looking forward to the final results!
