Okay, so I finally received my Hotech collimater and went to work. Got the laser pointing on the center mark on the primary by tweaking the secondary (thanks Bobs knobs) and then lined up the primary so the laser was returning correctly as indicated on the collimater faceplate. Job done - easy! Too cloudy to do a star test, time for a beer! Hmmm, lets have a bit more of a read about collimation just to check.
Damn, OK now I am confused. I think I am reading that I need to make sure the view from the focus tube (using the 35mm canister trick at least) is exactly centred in the secondary mirror. I know I can use the centre screw on the secondary to position it a bit higher or lower to try to do this as it does look like the reflection is a bit higher than centre.
So my question is: despite the laser collimater saying all is good do I need to do the above adjustments and if not am I decreasing the efficiency of the scope with reflections off the primary missing the secondary? BTW I can see all the primary clips evenly if that means anything with this issue. I swear I have only had one beer
Cheers
