M27 cropped
Shot with QHY8, 12 inch newt
While waiting for my spacers to arrive for the MPCC i shot M27 given its a small target it would fit into the centre of the image where coma isnt so bad, image cropped tightly as the rest didnt look so good.
Note M27 does not rise to even 30 degrees altitude here, so shooting through lots of atmosphere.
Spacers have now arrived so next images will be sharper.
For those that must have the info
20x 360 sec exposures shot over 2 nights.... lost most of first night due to fog
40 Dark Frames
20 Flats frames
20 Flat Darks frames
20 Bias frames
Median combined in Deep sky stacker.... was pleased to find it stacks and calibrates FITS files and even has a setting for the QHY8. Minor adjustments in photoshop. (curves , levels and saturation.)
