M33 Triangulum Galaxy V2

M33 Triangulum Galaxy

 

The first thing to realise is that at my field of view the M33 galaxy is much smaller than the galaxy. This means that right to the edge of this image contains the galaxy only and no background space, this is why there is not black sky and the resultant image looks slightly speckled due to the unresolved stars. I could do with much more luminance data on this object which I may get next year and then reprocess. This version is slightly brightened compared to V1 also posted and shows more of the outlying structure of the slightly unresolved arms.

Description - This is the first serious attempt at a galaxy through the scope now I have the tertiary baffle fitted. I have now added the colour to the original luminance frames that I stacked 1 year ago! I'm quite pleased with he result. I lost a bit of the image due to a slight rotation in the RGB frames from that of the luminance. However the galaxy is large and fills my chip. I would have to mosaic to fit it all in. I thought I was having problems removing noise and finally realised it was small unresolved stars across the entire galaxy, after checking many other photos on the web and some from the Subaru telescope.
