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.
