You will always get a very slight secondary off set in f6 to F3 newts , it’s an optical illusion due to the reflection in faster optical systems
I imaged last night and used Rigel for my frame and focus and the Star shape was nice and crisp with uniform shape except for the diffraction spike east west as mentioned in my post
Today I pulled out the primary gave it a wash and clean , reinstalled it , cleaned the secondary in situ and collimate again using my Cheshire and 2 different lasers
Tonight’s cloudy so will have to wait until early next week , maybe Tuesday before I can image again
Thanks for your reply
Newts can be a bit of a problem child sometimes but I enjoy the aperture especially my 12” goto visual scope
Cheers
