Description

Combining multinarrowband and wideband images as well as multiple exposure time (30s - 300s), yielded a significant improvement in details revealed, especially in the outer arms of M31. The strategy would seem to be suited for most extreme dynamic range targets available to us (M42, here's lookin' at you!) but more experimentation is needed, particularly with going even faster in exposure time (<1s).
Combining narrowband data, particularly in Ha, clearly shows red blobs of nebulosity in the outer arms of Andromeda, which, considering it's a whole other galaxy is quite impressive.
