First narrowband image with the new rig. The Pelican Nebula in SHO.

The CDK14 with the 0.66x reducer is very well suited for narrowband nebula imaging. The FOV is about 1.5 degrees with the full frame sensor, it was a bit too much and I had to crop a bit of the frame for my taste.
Being almost 50 degrees latitude north meant there no astronomically dark nights (not even 30 minutes) at this date, but I finally finished finetuning the setup and wanted to get some data regardless. It turned out better than I expected.
The combination of aperture, fast focal ratio, very narrow bandpass and the very low noise QHY600M meant a decent amount of data could be captured despite the conditions and Bortle 6 suburban sky.
The image scale is 0.465"/pixel and was downsampled to reduce the image size showing the "big picture".
Integration:14h
Bortle Dark-Sky Scale:6.00
