Another test image. The little quad's focal length is a bit too much for the object. Why not try the TS-CCD47 reducer I use for the RC8? Because it does not work. Looking at the full res image you see that there is astigmatism everywhere. The image is still good enough for full HD resolution. As the Ha only looked a bit boring I colorized the nebula and kept the stars white.
