m81 and m82
Wide field view of m81 and m82, the 135mm lens is starting to show it's limited resolution as i cant get much detail on m82 but overall a nice result.
Gear used:
Camera: canon r7 (unmodded) with a iso of 640.
lens: canon ef 135mm f2 l usm, f/3,5.
mount: skywatcher star adventurer 2i.
2 hours and 48 minutes of light frames of 30 seconds, 30 dark frames, 40 bias frames, 20 flat frames.
processing:
siril: stacking, green noise filter, plate sloving, spectrophotometric color calibration, starnet star removal, generalized hyperbolic stretch, histogram transformation.
graxpert: image crop, background extraction, noise reduction.
gimp: saturation, sharpen (unsharp mask), curves adjust.
