Description

Acquired this target from June 2 to June 9, 2020, at Bortle scale 7 location. The narrowband filter did help a lot to reduce light pollution. This was my first time mounted TEC 160FL on A-P Mach2GTO without modeling. In order to take advantage of the optical of the telescope, I decided to use a full-frame color camera - ASI6200MC pro. Used bin2 did help to reduce the exposure time and retain the contrast and high signal to noise ratio. I didn't do much on noise reduction, however, there were a lot of small stars in the frame which I spent some efforts to reduce the star size in Pixinsight and further done in Photoshop.
