Image processing: PixInsight, Lightroom IC 1396 – Elephant Trunk Nebula – Jun 2022 Ha BW v1 Annotated Image acquisition: CdC, NINA, PHD2, dithering Skywatcher Esprit 100/550 ED, Skywatcher Flattener, Baader CMOS-optimized Ha 6.5nm / QHY268M 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.īackyard astrophotography in light-polluted Cologne-Dellbrück SQM 20.0 is the maximum I measured in my backyard in spring 2020 with the excellent “lock-down” skies. 3 hours in the range of SQM 19.5 to 19.9. An “advantage” of the light polution here: even so astronomical twilight isn’t reached, the sky brightness is for approx. Since the Dec drift was to the North, I set the Dec guide mode to South. I checked to see which way the Dec was drifting (North or South).
I performed a PHD2 calibration and started guiding, but, with the Dec guiding OFF.
IC 1396 – Elephant Trunk Nebula – Jun 2022 Ha BW v1Ī quick capture during a clear mid summer night. I chose the RA only dither setting in PHD2 (Global tab).
