Hi guys,

I've had my Bintel/GSO dob for a little over a month now, and I'm finding that the bolts that hold the circular side bits (ie: the altitude bearing bits that sit in the dob base) to the OTA are coming loose. I tried tightening them with a screwdriver, but on closer inspection it looks like there are nuts inside that I need to keep still while tightening it.

What's the best way to reach in to the telescope to hold the nuts still? The secondary mirror stops me reaching in from the top, but it'd be quite a stretch anyway, so it might be best to take the primary mirror cell off and reach up from there. Is that easy enough to do? Will I have to recollimate the scope afterwards?
