Fintan Posted June 6 Share Posted June 6 Hi all, I’ve tried to see if this is answered elsewhere, apologies if it has. I bought a a Sky-Watcher 9x50 right angled finder scope to replace the red dot finder that came with my Heritage 150p Virtuouso GTI. I assumed it would be possible to connect to the same mount as the red-dot finder but now understand that might not be possible. Are there any solutions that don’t involve drilling as the thought of drilling holes in my telescope fills me with dread. Any suggestions welcome Link to comment Share on other sites More sharing options...

Took the primary out (I marked the orientation of the collar with masking tape so I could replace the cell the same way, hoping to reduce the re-collimation. It hardly needed more than a tweak .) swathed the secondary in j cloths & a plastic bag plus more masking tape, obviously with the front section opened out. Marked the holes needed on yet more masking tape, drilled with a brand new metal bit - it was my first go drilling anything metal - turned out to be easy. In order to decide where to place the RACI I temporarily fixed the shoe on the 'scope tube with double sided foam glue strips - the sort of thing used to stick number plates on cars. I cleaned the surface with isopropyl alcohol first, and the strips held so firmly the shoe took the weight of the RACI easily with just a little give (because of the elasticity of the foam) . The location I chose worked well, and the foam pads were so good that I left them doing their job for a few months while I worked up the nerve to drill.

Heather Thanks for the response, I might do the same and try the glue strips first. Link to comment Share on other sites More sharing options...
Tiny Clanger Posted June 6 Share Posted June 6 I've had a look through the photos I've uploaded before, here are some showing where I put the finder this angle shows the RACI is located so it parks neatly between the RDF and focuser when the 'scope is closed. If I can find the package I'll let you know what brand I bought. 1 1 Link to comment Share on other sites More sharing options...
