hi all
well i picked up a 10 " dob a week or two back and am a little lost on the secondary adjustment screws .. which does what.. I watched that good
video link thats been posted round here and it is great ..but his adjusters look a little differant to mine ?. pictured below is what I see through the barrell, things are all square but just a touch off, in that i can see a
little of the secondary holder on one side ... do you think it needs a tweak ?which screws do I loosen to adjust ?
Thought I'd better ask someone after my little "incident " this
morning with the primary .. it was a little off centre so i thought i'd have a shot at a fine adjustment of it ... I had read a lot and was still a little
apprehensive about it all and was definately thinking way to far ahead as i started .. slackened off locking screws ..(insert brain meltdown )
and decided the first adjusting screw i came to after doing this was also
a locking screw and happily started unwinding it as well
seeing the mirror cell moving markedly in the tube while doing this!!
Realiseing what i done I left the room in dissgust to make a cuppa
and when i came back couldn't remember which screw i had wound out
So what was an easy fix of just winding it back in was gone now
In the hour or so i spent trying to find my way back to the centre again
was loads of fun ..at one point i even had one of the adjusting screws completely undone so as to lose the spring on the floor ..A long time later I got close enough to slip the chesire back in and actually was getting
very good at moving the cell where i wanted it .. its perfect now
And I learned a lot .. noteably primary out of the box was only about 1/16th of a turn on one screw away from alignment.
any advice on what not to screw up with the secondary mucho appreaciated
