Dennis,
I noticed your using the Prima Luce Lab 60mm guide scope 240mm fl which have support rings not clamps
I’m surprised your getting such great guiding at 2000mm fl with support rings ?
I’m currently using an Orion 60mm guide scope with support rings but only imaging at 1000mm ( 8” f5 GSO newt ) guides around 0.60 to 0.70 total rms
Folk have advised to choose support clamps in lieu of rings to minimise movement and differential flexure when imaging over 1000mm
Obviously your kits working well
Any further comments on the type of Guide scope
For my new scope arriving in May ( 10” f5 KH carbon fibre ) I was considering a Williams Optics 61mm GuideStar Guide scope 320mm fl which has clamps and only weighs 1.4kg ( new mount as well EQ8-R in my NexDome )
