My image of the nebula region around the star Sadr in the constellation Cygnus. The pictures were taken on four nights with a TS-Photoline APO 360mm, using a UHC clip filter for my EOS 750Da. The total exposure time is 6 hours, which consists of 60s and 180s lights.
I hope you like it 😉
Clear skies, Stefan
Yes, lots of details. I'm missing a bit of color though, this filter shouldn't supress too much color right?
The pictures were taken in July this year at a warm outside temperature. The chip temperature of my EOS 750Da was partly 29°C and the darks and flats of course have different temperatures. Of course this is not ideal for processing the pictures. This is the big disadvantage compared to a cooled CMOS camera.

Ah it blocks a decent amount, mainly for light polution purposes.
edit: no blue shouldn't be blocked. So interesting why that's not present here. Anyway, food for thought in a next attempt maybe. 😉 Could also be due to the exposure, if stars get saturated color is lost as well.
