Yes and no.
Sorry for the long post earlier, obviously too long for people to read, which is fair enough, so the gist of it is:
Starkler's advice on collimation I could only take as far as the visual inspection thru the focuser, and it looks OK.
Film canisters do not fit in the focuser.
The star test is a bit hopeless. You can see some fuzzy arcs of circular fringes, and I can't really improve on it at either mirror.
In a scope shop I was told to only adjust the secondary mirror when doing the star test, and I should leave the primary alone. But my not-so-common sense tells me that I should adjust the secondary first until centre of main mirror appears in centre of view at the focuser (easy with a laser) and then adjust the main mirror (so that with a laser the incident & reflected beams follow the same path).
Have I got this right? Then I can try the star test and fiddle with which mirror?
