Starting to look the goods now. I think the axis offset I found on the primary was causing most of the grief. I had this scope textbook aligned on the bench, as soon as I put it back on the mount and double checked, it had moved.
I believe that is another issue to be looked at later as my back was also complaining today so I didn't want to spend much time adjusting alignment on the mount. Just did a quicky so it was close. The light cone is off to the left in these images so even though alignment is not perfect the stars are way better than they were in earlier images. FWHM is down as well.
I notice that inside focus a star test shows a lump on one side while outside focus the lump is on the other side. I'm hoping that this is normal and correcting the alignment will have them both concentric.
Here's 253 and tuc, without and with the mpcc. There is obviously some camera tilt going on in there as well so concentrate on the center
Also added the 253 center star close up, last week and today. I got some 5 minute colour 253 coming for a look see.
