This is the Ha channel of project in progress and being just mono image it doesn't mean that have to be black and white :) So colored it in blue...

It is mosaic of 3 panes and uploaded is the full scale image. Open it in full resolution to see the faint details :)

The acquisition is 4.5h per panel. Currently have gathered ~1.5h per panel in OIII but hope to round them at least to 3 for finishing the project.
