Ratlet Posted March 4 Author Share Posted March 4 Does anyone know the size needed for the secondary collimation screws? Would like to get some ordered whilst I wait for D-day. Link to comment Share on other sites More sharing options...

CNsec35 that’s the part number on FLO. The 8, 10, and 12” are the same. Link to comment Share on other sites More sharing options...
Kobayashi Maru Posted March 6 Share Posted March 6 I would reiterate the benefits of tweaking the mount on the cheaper dobs. Replacing the needle bearings with Teflon pads did wonders for my 10" GSO. Link to comment Share on other sites More sharing options...
Kobayashi Maru Posted March 6 Share Posted March 6 ...and the size. A 10 inch is a big boy. Mine is a solid tube and pretty awkward to move about. The truss dobs would be easier but have other issues obviously (collimation, light shrouds, set up). Link to comment Share on other sites More sharing options...

The truss dobs would be easier but have other issues obviously (collimation, light shrouds, set up). Fortunately, the size shouldn't be a major issue. It's going to live up the shed and have to go about 8ft to where it will be setup. Got a sack barrow if I do struggle. I'm holding fire on upgrades at the moment, but I've got a list of links to different things people have done on here, including the roller bearings (either going to teflon or lazy Susan). It's been a test of my moral fortitude to not go completely nuts on getting loads of bits for it, was this close to getting the encoders. So far I've only gone for an inclinometer (really want to try setting circles) and some stuff to flock it with. When it arrives I'm going to make a template for the base parts. I'm not a huge fan of particle board so I'm wanting to try remaking it out of exterior grade plywood and varnish. Also having seen some of the home made dobs, I think the plywood and varnish gives a really nice 80's vibe. Link to comment Share on other sites More sharing options...
Ratlet Posted March 6 Author Share Posted March 6 That being said, I'm not sure what's going on, but desperately hoping the delivery date is correct and so is the clear outside app lol. 1 Link to comment Share on other sites More sharing options...

Littleguy80 Posted March 7 Share Posted March 7 It’s been 5 years since I went from 130mm and slo-mo controls to a 10” dob. No regrets at all. It’s still my most used scope. Love it and I’m sure you’ll love yours too. Great way to mark your 40th! 1 Link to comment Share on other sites More sharing options...
Ratlet Posted March 7 Author Share Posted March 7 Ah well. Never mind. Should still be clear on Wednesday. Full moon isn't ideal, but I've got AG's double book and really keen on starting that. @Mr Spock has got me fired up on them and also really want to try some better logging. This far I've been basically using the "what I saw tonight' thread to track my observations 🫠 Link to comment Share on other sites More sharing options...

Ratlet Posted March 31 Author Share Posted March 31 Belated update after bedding in, only adding because I can't stand threads that don't reach a conclusion. An update if anyone finds this and wonders how I got on, the scope is brilliant. Still getting to grips with the fine detail but it is meachnically sound and wasn't a challenge at all moving from slow mo to nudging. In terms of getting to grips it is just dialing in the tension and balance on the altitufe so far, a bit like backlash, but that'll come. Azimuth responds well although I have had a bit of a rock on fine adjustments where it kind of rolls back to the direction it was pushed from, almost like it is rolling up a hill and is rolling back. I should add that the azimuth problem was only really noticeable at x400 power... No regrets at all and it takes about the same length of time to setup from my shed as the 130pds did. 3 Link to comment Share on other sites More sharing options...
bosun21 Posted March 31 Share Posted March 31 I found that the slight rollback was solved by attaining a better balance on the scope. It should remain in position with only a minuscule if any tension on the side locking adjusters. I found this point of balance on my dobsonian with the addition of a movable magnet. 1 Link to comment Share on other sites More sharing options...
