NGC 6744 – Pavo Galaxy – v1

Almost exactly 10 years ago, I photographed the magnificient Pavo Galaxy with the IAS 20 inch AK3, my first object with such a “big scope”. Here’s the result of June 2024, with much more exposure time on the very same telescope. I originally planned to use my QHY268M with the AK3, but this camera is now used at the new IAS remote telescope. So back to the roots with a ASI294MC Pro one-shot-color camera.

Das sieht man auch nicht alle Tage: Polarlichter in allen Farben über den ganzen Himmel bei heimischer 51° Breite, nordöstlich von Köln. Ein massiver Sonnensturm trifft gerade auf die Erde.

Another image from the total solar eclipse of 08 Apr 2024, a highly processed HDR composite of the corona, using 13 x 2 exposures from 1/1000 to 4 s.

There was a bit of a focus problem which I noticed only when reviewing the telephoto frames. Thus, my TSE 2024 shots aren’t as sharp as they could be.

Pocahontas, Missouri, USA
