Frank C. Posted April 2, 2022 Share Posted April 2, 2022 My name is Frank. Recently retired, dusting off myself and two EX 125's. I could use a little advice regarding a focuser upgrade. Would a 2" DIagonal work well with my 125mm scope? I believe I need to have a SCT visual back adapter to make this work,correct? Many thanks!

Nightspore Posted April 2, 2022 Share Posted April 2, 2022 Welcome to the Yard Frank. Apparently the south east coast is the sunniest part of England. Although I suppose it depends which south east you're talking about lol. Not sure about your Meade. Does this help? Quote Link to comment Share on other sites More sharing options...

I've wondered about a 2" visual back for my Synta 127mm Mak'. I know some are sold with one. Although to be honest I'm not sure what the advantages are for me.

GazAstro Posted April 3, 2022 Share Posted April 3, 2022 Welcome Frank ... 2 ETX 125s, I can feel a monster binocular build coming 😄 Quote Link to comment Share on other sites More sharing options...
Frank C. Posted April 3, 2022 Author Share Posted April 3, 2022 I just completed a total teardown of my first ETX 125. The drive motors put on a wonderful smoke show shortly after I purchased it many years ago. I removed the OTA and trashed all but the tripod. I later found a mint condition 125 and adapted it to a standard tripod. Great optics and very well cared for. I recently had too much time on my hands so the original scope went on the operating table for bypass surgery. The plastic back was removed and I put a draw tube on. Removed primary and cleaned it along with the secondary. Colimation wasn't too difficult as the screws were indexed. My intention is to keep it as a backup but it will have limitations. The newer ETX I intend to use visually and want it to be spot-on. Now to the question in my rather lengthy post..... apologies to all. Will a 2" focuser with SCT adapter provide good imaging without a focal reducer? If so, what focal length should I use. I will be upgrading to 2" eyepieces. Many thanks.
