Totally agree John. I'm probably well into OCD territory having used my Newt for astrophotography for many years some time ago. The effects of the impinging drawtube and a twisted vane are then visible as imperfections in star roundness and tightness of diffraction spikes respectively.
Was interested to read your comment on lasers - always found a cheshire to be a dependable guide. For mass-produced Newts, movement in the focuser, tube flex, or mirror movement (along with the challenge of most cheaper lasers themselves not being properly collimated) is a problem. Ironically, you only seem to get maximum time saving benefit from a laser after having invested a lot of time beforehand learning basic collimation skills. For a beginner with no assistance nearby, a laser can be frustrating experience.
How do you go about setting up and checking the "big newts", out of interest. With a decent laser, or something like catseye tools?
