Hi,
Thanks for everyone’s comments and help. It is much appreciated.
To give an update, I dropped the primary mirror right back and then collimated the scope again. This has not had the desired effect as the eyepieces still focus at different points and I need to switch extension tubes. Maybe I pushed the primary too far up again - I will need to go back and re-check its position during the next collimation.
In the meantime, I have followed MortonH’s advice and purchased the 1.25 inch extension stub, which based on the current focal planes should do the trick.
In regards to the eyepiece discussion, I will play with my current eyepiece collection for a while (ES 24mm 68 is on its way) to see how it all works for me. Clearly there are many different views out there with regards to the best eyepiece. I am very much enjoying the 13 mm Nagler and also the 8.8 mm ES, but haven’t had a chance yet to try other brands, including the longer focal length ES. I don’t mind refocusing, but switching extensions or slightly pulling eyepieces out is getting old real quick.
Cheers
