Description

Stock DSLR and unguided.

Although I got 8 hours of additional data in autumn of 2018, it turned out during the integration that there was a (moving) dust particle on the sensor, which even disappeared before I took the flats. :/

The 7d II has visibly higher signal and less noise than my last camera (1200d), however, because of the banding I couldn't try a really long exposure subject. To solve this I wrote a script in PI, for which this was the first real tough test.
