I have been having what i thought ws collimation / tilt issues, and now i thinkwhat happens is MAYBE i have a faulty Coma corrector....

I cropped this image, it was a quick narroband test last night....

Maybe going back to PARACORR or RCC1

Did you use a Baader MPCC prior to that?

You've successfully shown a special thing that we look for in this nebula:

There is a very bright star underneath the chin. Coming out from that bright star are two "bolts of blue lightning", one heading toward about 8 o'clock and one heading toward about 6 o'clock. Not many images successfully show those.

Well done!

We'd love to know the astrophysics of it all.

Best,

I used MPCC on F5, then i found it inefficient on f4, moved to Paracorr, then RCC1 and finally GPO, this GPO is the one that gives me more sharpness but i am still troubleshooting some tilt,,,
