M81 Bode’s Galaxy and M82 Cigar Galaxy in Ursa Major – LHaRGB v2

Old data revisited: 3 years ago, back in 2022, I collected a whopping 38 hours of data on Messier 81 and Messier 82, a nice field of view with lots of smaller galaxies for my Esprit 100ED APO at home. But I never managed to get to a satisfying rendition up until now. The new NoiseXTerminator version AI3 was released at just about the right time. Under suburban Bortle 5 skies, this massive amount of exposure time is really necessary to bring out the dust streaks.

Cr 399 – Coathanger in Vulpecula – Jun 2023 – LRGB v1

Back to the roots. After all the data acquired under pristine Namibian skies, both locally and remotely, I managed to capture the Coathanger Asterism in my backyard. A few days after summer solstice, when astronomical dusk isn’t reached during the night.

IC 1396 – Elephant Trunk Nebula – Jun 2022 Ha BW v1

A quick capture during a clear mid summer night. An “advantage” of the light polution here: even so astronomical twilight isn’t reached, the sky brightness is for approx. 3 hours in the range of SQM 19.5 to 19.9. SQM 20.0 is the maximum I measured in my backyard in spring 2020 with the excellent “lock-down” skies.

Hopefully a break in the currently cloudy and rainy weather for some additional O3 und S2 data during the next days before the moon returns.
