Description

I shot this last year with a OSC and the Triad filter and went after it this time with mono and SHO filters. I was surprised with the strong S2 signal on the far right of this image. 

I had to get my long focal length setup going on the AP900 mount, so as I was collecting data, I worked on the EQ6R mount. Stripped it completely, replaced all the bearings, and put it back together and installed the ADM saddle (stock puck was tilted badly). I would not essentially call it a hypertune yet, but it is performing decently to not give me mini heart attacks like before. I do need to take time and tune the backlash and run PEMPro again, but will save it for a partially cloudy night soon. 

I hope you like this result. Clear skies!
