Hi Mick, the 150 Newt shows great potential imo & a remarkable image given the lack of guiding. With regards to your focuser issue, I had a similar experience with a GSO crayford on my C8
& found that adjustment of the guide bearings on the top played a critical role in offsetting the focus lock thumbscrew on the bottom. The end result was less pressure was needed when applying the focus lock,
I also replaced the metal thumbscrew with a plastic one which seemed to add a degree of finesse as well. Most of these Chinese crayfords require some tweaking it seems.
Hope this info was of some use.
Cheers,
Tony
