Description

I don't often image galaxies with my Baby-Q but a couple of clear nights back in April 2024, near to the full Moon, presented themselves so I thought I'd have a go at the Pinwheel. There were some severe gradients which I managed to control with PI's new GradientCorrection tool. I took some Ha which I blended with the RGB, both from my OSC camera.
