quick'n'dirty
I haven't processed these images other calibrated and combine them, followed by a very quick and dirty DDP stretch. I have individual RGB data to add, but didn't bother. Also took some Ha, OIII and SII which I haven't worked on yet - might be interesting. These are simply the cropped luminance shots. Taken with a TOA150 and ST10XME. The images are nothing special (certainly don't give me a buzz like DSO images).
More image info (out of FITS);
