This is the first remote image from my new observatory in Burlage (Germany).
I'ts been almost a year now since construction started, but everything starts working properly now. This image consists of 7 x 600s Luminance, and 1 x 600s each for RGB. Only darks and bias were used for calibration, no flats were shot yet, so I used DBE in PixInsight instead.

Seeing was not great, and the images were quickly taken inbetween rain showers...
There are still some issues with collimation and camera tilt, but I'm getting there! A remotely operated flatfield screen is first priority now.

I noticed I get a lot more signal in a short time at this dark location!
