Thanks Martin. Still a very slight tilt as I forgot to hang the camera down.
I understand. Sounds like a lot of work..
I have considered a larger sensor with larger pixels.
I had enough trouble with the 183 which really has too smaller pixels for the newt and is better on the refractor. Looks better with the UV filter and CC for smallish objects for sure than when I first started to use on the newt.

Well done !!
Your image train and resultant FOV is bit more forgiving than on my 8” f5 newt
Your FOV with the 183MC is 45 x 30 arc mins
Mine with my 2600MC is 81 x 54 arc mins so I’ve have a bit more field to correct especially in the corners ( and even wider on my 6” f6 newt )
It took me many nights to get the spacing just right as you know. Factors like tracking , guiding , seeing , objects altitude , wind , humidity, dew , Collimation, tilt etc.... all can affect your Star shape which doesn’t help trying to set your coma corrector.
