Description

Another shot from a Bortle class 3 site in Texel, NL. I think every time we catch a couple of days of clear skies I will just take my telescope and go back to Texel! The difference between Amsterdam and a dark site was just unimaginable for me.

This is also the first shot I took with the ES127 and the 1.0x TS-Optics flattener. They go together very well! Happy, especially after I had to give away the TS-Optics REFRAKTOR 0.79x 2" flattener/reducer as it was working especially poorly with this telescope (elongated, CA stars on 50% of the image).

One thing I regret about this shot is using the Astronomik CLS-CCD filter in a dark site - force of habit The CLS CCD is a good filter for strong light pollution, but the color balance is strongly shifted to green; took quite a few hours to properly color correct this image.
