Never let a clear night go by, and not my usual sort of target of late, but this is a quick effort at the Southern Pinwheel galaxy to try and bring out the Ha nodules. Taken in one night, with 60s subs in LRGB and 120s high gain Ha subs, total time was only a couple of hours. Camera is the ASI1600MM-C, scope is a 10" f5 imaging newt on a CGX mount. Processed in DSS and Photoshop CC. It needs much more time spent on it and more processing attention I know. I may get back to it in coming weeks to create a new version. There is a little gradient that I have to work out. The Ha nodules are seen in magenta in this image.
