So 2 topics here:
I have this scope:
https://www.teleskop-express.de/shop/pr ... actor.html
That I use for night time and white light. It has a 3.7" focuser which can handle a lot of weight but the clamping system that takes the diagonal is really poorly designed. So much so that it just dropped my 2" Herschel wedge and eyepiece, and that's before I even had the binoviewers on top of that.
Amazingly the herschel wedge "survived" the fall, none of the lenses inside broke, however the ceramic heatsink at the back popped off and seemed to have sheared off the screws with it. Any thoughts about repairing this or should I just get a new one ? (the smudge you see on the lens is where my finger touched it to confirm it's still there, no damage)

Re: Dropped my Herschel Wedge
Would a thermal heatsink glue work to put the sink back on the wedge?

That's a good idea. I do have some two part thermal cement that could workDeepSolar64 wrote: ↑Mon May 29, 2023 10:11 pm Would a thermal heatsink glue work to put the sink back on the wedge?

Research it first and make sure it will work. I am not sure how hot the wedge will heat it. It probably depends on the scope's aperture.

Re: Dropped my Herschel Wedge
You don't need to replace the wedge.
Extract the sheared off bolts and replace them with new ones. If you can't do this, use a high temperature epoxy and glue the heat sink back in place and you be good to go.

Re: Dropped my Herschel Wedge
Definitely don't need to replace it. Do you have a screw / bolt extracting tool? Get the sheared bolts out and replace them,
