Thanks for all the feedback team, and especially to the C9.25 gang for confirmation that they are seeing similar results - that is quite re-assuring as I still seem to get some soft or low contrast images.
In several of the less distinct and distorted frames, the bright central dot oscillated in a pattern (similar to Lissajou figures) around the actual centre and I thought that my collimation might have been off. But, I just put this down to the results of scintillation during times of less steady seeing.
Wow – Paul; you are a real scientist – keeping records of collimation! I’m still learning after reading yours, and others posts on collimation and I must say, the more I practice the easier it gets as the “fear of tweaking” is displaced with positive outcomes.
Cheers
Dennis
