Marmot Posted April 29, 2021 Share Posted April 29, 2021 Hi i wasn’t sure where to put this post, but I feel this section is as good as the other alternatives. It’s my first attempt to attach a couple of photos so I hope it works! I have only been involved with this interest for a few short months, but I thought the following information may be of interest to other people new to the game who experience the same issue as I did and the solution I found. I am the proud owner of a Skywatcher ST 120 which, for the time being, does everything I want. However, soon after acquiring it I became a little disappointed with the way in which the diagonal attached to the drawtube using a basic thumbscrew. This applied to the 2” adapter (attached directly to the drawtube) and the 2” to 1.25” adapter. A quick search on the Net revealed a direct replacement from Baader using their “Click-Lock” attachment method. This seemed ideal, but reviews revealed it to be a little more bulky than the original and therefore using up a little of the focus movement. I set my scope up using the diagonal and eyepieces I thought would use up the most light path to see how much focus was left. The result showed that I only had a few mm left. For this reason I decided against the Baader Click-Lock feeling it would be a close call to achieving focus in certain situations. i then came across the Astro Essentials 2” compression ring M56 threaded replacement supplied by FLO. It was advertised as a direct replacement and being slightly lower profile than the original. It was also only slightly over half the price of the Baader Click-Lock. i purchased it without hesitation. The swap was easy. And it does indeed give a couple more mm inward focus travel. i was then fortunate enough to find a Baader 2” to 1.25” compression ring adapter on eBay for a good price. hopefully the attached pics show the result. I now feel that anything attached to the focuser is held in a safe secure manner and that there Will be sufficient ‘in focus’ to cope with any combination of my existing diagonal/eyepieces etc. 2 Quote Link to comment Share on other sites More sharing options...
