Converting 9x50 raci finderscope to a guidescope

[AstroNebulee]

Hi

I've seen before an article on converting a finderscope into a guidescope I have a sw 9x50 raci one and how to connect it via an adapter to use my zwo asi120mc-s for guiding if this is possible. Any help will be greatly appreciated or is it simpler to see if there are any  lightweight guidescopes for sale on the used market. 

Kind regards

Lee,

It's possible to convert the SW 9 x 50 into a finderscope.  You have to remove the "eyepiece" section from the tube and fit an adaptor in its place to suit your camera.  I use an old QHY5 that has a standard (C or T) mount adaptor thread so used one of these adaptors https://www.rothervalleyoptics.co.uk/finderscope-c-or-t-adaptors.html to connect the camera to the finder.  Not 100% sure it would work with out an extension on a RACI version as the focal point may be behind the camera.

There are plenty of small guidescopes available, including packages deals with cameras  https://www.rothervalleyoptics.co.uk/telescope-guidescopes.html?scroll=1513

It works with RACI but you need to provide 40mm T2 extension between above adapter and camera (it is pointed out on FLO product page)

Thanks for the replies, sorry I haven't replied before but had no notification. I have since contacted FLO and they have suggested the two parts needed to guide with my 9x50 fs, a adapter and the extension tube then I can fit my zwo asi120mc-s, thanks again 👍 clear skies
