Description

Lights: 1200 x 30s (best 95% selected)
Darks: 10 x 30s @ -10C
Flats: 20 x 12.9s @ -4.5C (taken at dusk)
Dark flats: 20 x 12.9s @ -4.5C

If you have above moderate light pollution, then don't bother with the special RASA8 Celestron Light Pollution Imaging Filter. Your images will be washed out. Instead the Optolong L-Enhance is quite a lot better for color cameras. The L-Enhance appears to have the same transmission chart as the Celestron H-Alpha H-Beta OIII Imaging Filter.

Still fighting some sensor tilt with the RASA 8. I tried various hacky solutions to tilt the sensor, but in the end just went with a secure fit onto the Starizona Filter Slider and I just 'live' with the elongated stars at the corners. Maybe the Baader FCCT (Filter Changer and Camera Tilter) will be released this year.
