Hi Taxman,
sounds like you're having fun alright
.
It can be a bit tricky when you start, but you will get it right if you keep going.
To collimate, what I did was - when it came time to adjust the primary mirror - I clearly marked the adjustment screws #1, #2 and #3 in black marker. Then I got a willing helper to assist. So, whilst I barked orders like "#1 a half turn clockwise [for example]", I was able to view the effect the adjustment made simply by tracking the red dot of my laser collimator on the face of the primary.
With today's laser collimators, you can line up your mirrors so that the secondary reflects the beam onto the centre spot of the primary, and then the primary reflects the beam back up onto the secondary and into the centre of the EP. In other words, so that the light path into and out of the scope all lines up as it needs to do to acheive focus.
Having said that, some people quite rightly will suggest a laser collimator has limitations, but assuming your secondary is lined up approximately ok firstly, the above procedure works a treat.
Hope it helps.
Cheers
