The Swan (or Omega) Nebula M17 is a great target for the ED80 at F7.5 600mm Focal length. Taken on a HEQ5 pro with ASI 533 MCpro. I did 150 x 240sec.
I processed in Pixinsight and photoshop. I'm slowly getting my guiding sorted on the new mount (tightened the backlash on both axis). Not 100% happy yet but ordered an OAG which also may help. I have a belt mod kit ready and waiting as my last line of defense! I only put a Astro tech Flattener and not a reducer because I wanted to get close. That means I need to guide at 0.56 RMS on average! Ill add some Sii to this image to tease out the detail more.
