Re: Problem with broken base of ETX125 finder
|
Good evening, The RDF is fixed again with QuickSteel epoxy paste! It was easy. After a good kneading, it heats up. It's time to glue. I aimed at a minaret clearly identifiable by its green lighting at about 1 km that I placed in the center of the ETX field and I tightened the mount fully. I applied the paste around the broken base of the RDF, I applied it well against the tube and a few minutes later, I placed the red dot on the minaret and held in place with rolled fabric. After 20 minutes the paste is hard as metal and the RDF is very well glued to the tube.
Success! Here are photos, before and after black nail polish... Best and thanks for help?! Sylvain

So when did they start fitting that kind of finder?? I have one
of the very early models when it came with a dreadful tripod but?
a very nice right-angled finder that sits right beside the main
eyepiece.? I can almost look through one with one eye and the
other with the other eye.
I hope you managed to get yours mended, Sylvain.

Hello,
I'm looking for ideas ...
As you can see in the photo, the base of the finder
broke.
I had previously managed to glue it back together and
align it correctly using a good dose of hot glue. I had done
the alignment during the rather long cooling time.
Everything was fine until a very hot day when the ETX was in
the sun ... The hot glue softened completely and the finder
came off again.
So I can't use this glue with such a low melting point.
I spent a lot of time to successfully remove the glue! I
needed a cutter by bending the blade, my fingers, a cloth, a
wire brush ...
Do you have any ideas for making a more solid repair
taking into account that the rough alignment is not easy but
must be quite correct all the same from the start to be able
to use the two fine alignment screws ...
Thanks,
Sylvain
