Herb H Posted December 12, 2022 Share Posted December 12, 2022 I believe the collimation screws on the C70 follow the usual pattern, but I am not 100% sure. Three adjustment screws and 3 locking screws. Link to comment Share on other sites More sharing options...
happy-kat Posted December 12, 2022 Share Posted December 12, 2022 (edited) From when I had read about the C70 when stripping the back off was that there were three push and three pull screws, I'll see if I can add a link to what I'd found before. There's a post with picture of screws on CN. Mine is still waiting for collimation as it's a bit out from my fiddling, just to say the mirror coating is very delicate as I've scratched mine when flocking it.

Herb H Posted December 13, 2022 Share Posted December 13, 2022 Yes indeed, I checked again and the screws are push - pull, so you need to use all of them to adjust the mirror, slowly two at a time (the two neighboring ones). This time around I decided to remove that nice prism, so I would get a better un-distorted view through the scope. You can see now the alignment is pretty good. 🙂 It was not difficult at all, just a few minutes fiddling with the screws - two at a time. 1 Link to comment Share on other sites More sharing options...
RT65CB-SWL Posted December 13, 2022 Share Posted December 13, 2022 I would say that is 'spot-on'... pun intented! 🤣 Link to comment Share on other sites More sharing options...
happy-kat Posted December 14, 2022 Share Posted December 14, 2022 All's collimation aid is a great tool for checking concentric circle alignment, your C70 is much more aligned than mine and perhaps the camera needs to be totally square to know if alignment is true, I'll use a webcam with the tool to check mine.

Herb H Posted December 16, 2022 Share Posted December 16, 2022 You lost me there ... What is "All's collimation aid" ? Link to comment Share on other sites More sharing options...
happy-kat Posted December 16, 2022 Share Posted December 16, 2022 (edited) it is a small windows program (not by Microsoft) which helps with lining things up Edited December 16, 2022 by happy-kat Link to comment Share on other sites More sharing options...
