A little knowledge...

Postby Ryohei » 04 Nov 2012, 18:15

.......is a dangerous thing, as I found out when attempting to collimate my Skywatcher 150PL the other night. In short, I screwed up and now have a barely usable scope. I wonder if I could ask a member to help put it right and to give me some guidance for the future? I am in Glenrothes but happy to bring the scope to you. Thanks. Alan S.

I too have a laser collimator and some experience of collimating Newtonians.
I'll be at the meeting on 27th Nov, so if you're there too I can talk you through it.

Thanks guys. Yes, it's a Newtonian reflector. I tried adjusting both primary and secondary, following what I thought were clear instructions. However I think I got lost somewhere along the way and it got to the point where I felt I risked making things many times worse if I carried on.

Brian - I'm on a phased return to work at the moment, having been off sick for some weeks, so at the moment I'm leaving my work in Rosyth around 14:00. Given that I would be in the Bay somewhere around 14:15 or so, that may be rather too early for you. If so, then I am happy to wait until the next meeting - I will bring the scope along. Do you need the mount too, or is it sufficient to lie the scope on a table? Let me know if you need the moud so i have it with me.

Many thanks

Hi, yes I could manage Thursday. I'll send you a PM with my private contact details, maybe we could fix something up?

Thanks
