CraigT82 Posted February 7, 2020 Share Posted February 7, 2020 If you cant source any off the shelf OOUK will make tube rings in custom sizes. Not sure on cost though 1 Link to comment Share on other sites More sharing options...
johninderby Posted February 7, 2020 Share Posted February 7, 2020 (edited) Telescope Express does all kindsof tube rings including custom sizes. https://www.teleskop-express.de/shop/index.php/language/en/cat/c266_Rohrschellen.html The OO rolled tube rings are about £50.00 or £60.00 I think.

joe aguiar Posted February 7, 2020 Share Posted February 7, 2020 I think any dealer can order u this I did few different times. Just give them the size u need. They can see who sells best fit from celestron skywatcher or meade. Sometimes it may be 1mm off so just add bit more felt on rings Joejaguar 1 Link to comment Share on other sites More sharing options...

Carbon Brush Posted February 7, 2020 Share Posted February 7, 2020 If you have some rings that are just a bit over size, then you could look at 3D printing some reducers. HTH, David. Link to comment Share on other sites More sharing options...

RT65CB-SWL Posted February 7, 2020 Share Posted February 7, 2020 (edited) You could try Ray's Rings, (assuming he is still in business). He is/was based in/or around Peterborough. He made me a pair for my 're-modded' ETX105. They were 124mm, and I sold them on. However, if you want the cheapskate approach, you could always use a pair of Jubilee/hose rings which hold/secure the OTA to the dovetail bar in place and I now use, (image below). To prevent them scratching or marring the OTA, you will also need some and some strips of self-adhesive neoprene, cork or felt. Surprisingly it does work. The downside is you will not be able to rotate the OTA. edit: 17 hours ago, CraigT82 said: If you cant source any off the shelf OOUK will make tube rings in custom sizes. Not sure on cost though I did contact OOUK and was told that the smallest diameter they would be able to make was for 6"/150mm or above OTA's.
