200p Dob collimation fumblings

[ScottS]

I have just had my first go at using the GSO Revelation laser collimator that arrived last week. I was on the verge of sending it back as the on/off switch wasn't working correctly, but now bizarrely it seems to have cured itself (unscrewed the end, had a look, put it back together). So I think I'll keep it after all. Anyone else had any similar issues with this collimator?

Anyway, I digress. As it turns out, my scope seems to be well collimated, so had no need to fiddle with any of the screws etc, but I did notice at the back of the primary there appears to be the large locking screws adjacent to which are the 3 smaller adjusting screws. Then I noticed another set of 3 very small grub type screws on their own away from the other screws. Can anyone shed any light on what these do. I hadn't noticed them before.

Thanks.

Ps. I managed to collimate the laser by sitting it on top of a four pack of cider. Very crude I know, but it worked......so I treated myself to a refreshing drink after.

(Note to self: must get/make proper device for laser collimating).

I have one of these collimators and it works great. Even when I made a bags of replacing the batteries, I managed to recollimate the collimator just fine.

Don't know what the final set of screws would be. Can you photograph them?

Possibly that's a limit set-screw.

That would make sense as there are 3 equally spaced around the edge. I guess I should just leave these alone then if that's the case. Thanks.
