NGC 253 – The Sculptor Galaxy – one year on…


It has been almost exactly one year since I first shot NGC 253, and I’ve managed to acquire some new hardware and software in the past year that has made a huge difference. What better way to test my new gear and software than to re-shoot one of my first targets!

Registration and stacking was performed in DeepSkyStacker, post processing in PixInsight, and some tweaking in Photoshop.
