Done with my usual set up, that I'm now growing used to and am very satisfied with - the Celestron C8 with two reducers and the Altair GPcam mono V2. Captured using APT and guided with PHD2. I used the colour from a previous DSLR shot and layered it in using Photoshop. This is a stack of 5x300 secs and 4x600 secs subs. There are no darks or flats but in this instance the former would have helped. I normally use dithering but because the image filled the frame here that wasn't really an option. So the image was a bit noisy, though I've done my best to clean it up. The transparency was not as good as it can be at my location. I noticed when the Moon rose it was extremely red. I believe this is due to dust from the Sahara? :D
