Description

This is my first attempt at capturing integrated flux nebula, and I chose the area around M81 and M82. There are other galaxies in the frame too, notably NGC 3077 towards the top left, and I think the blue smudges are the two irregular galaxies UGC 5336 (just above M81) and UGC 5139 (bottom right). The broadband data is enhanced with Ha data captured using the NBZ filter - this just adds a little bit of colour to M81 and M82.

Bringing out the IFN and avoiding blowing out the galaxies is all a bit of a faff! I put some effort in to this, but I'm sure those with more patience and experience could do a better job!
