Description

I have tried to capture M97 Owl Nebula & M108 Surfboard Galaxy and startet with Ha and OIII using my Skywatcher Newton 200/1000 PDS and ASI1600. During the capturing a sold my Newton and bought a Esprit 120ED, so I could not finish this object with LRGB. I have tried my best with the existing HOO data.
