NGC 2997 Revisited

Already done in 2019, here comes another shot at NGC 2997, a face-on unbarred spiral galaxy in Antlia. Only 1 hour of total exposure time due to many technical problems with the 20″ Cassegrain.

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.

A new night sky time-lapse video from Namibia April/May 2022 is ready and posted to Youtube. Full HD, due to the size limitation not available at Vimeo. Enjoy!

Fast schon aus Verzweiflung ;-) zwischendrin ein paar H-alpha Daten vom Seelennebel, mehr war bei Mond und leichter Schleierbewölkung nicht drin, das Wetter in Köln ist leider in den letzten Monaten wenig astrofreundlich.
Nicht die erste Variante, die älteren finden sich im kompletten Artikel.
