finder scope for a dob

[bomberbaz]

As the title suggests I am looking at a finders, spec7fically I want a right angle version. The skywatcher version seems cheapest which is corrected for users of sct's . Upight and reversed.

Hope this isntva silly question but do the manufacterers do a version that is corrected for how you view the sky or am I missing something?

I use the Altair Astro RACI and so far pretty happy with it. The Explore Scientific version is corrected http://www.explorescientific.co.uk/en/Optical-accessories/Explore-Scientific-8x50-90-PolarFinder-Amici-Prism.html

Hi Steve,

The Skywatcher RACI presents the sky orientated as viewed naked eye.

Here's a link:- http://www.rothervalleyoptics.co.uk/skywatcher-right-angled-magnified-finderscopes.html you have the choice I use the 9 x 50 Right Angled Erect Image together with a Telrad mounted on a 4" riser.

Cheers fellas. Wasnt sure if raci was what I wanted, thanks

Yup - my dob has a RACI and a Telrad (on 2" riser) - both very useful. I just can't switch scope movements in my head for traditional finder optics - don't much want to either lol.

Actually just to clarify, the non erect8r version gives you the view as seen through the dob then, yes?

Hi steve,

i use the skywatcher raci which i think i got from flo. I think the shoe is extra though and flo seems to be the cheapest for these as well.

cheers

There are 2 versions, the RACI one which is as we see with our eyes and an RA one which is right angle, up and down corrected but left and right reversed, which is the refractor / SCT / mak-cass view. I currently use a Rigel Quikfinder RDF and a 9x50 RACI optical on my dob but I have used the other type of RA optical too. I prefer the optical finder to mirror the view my eyes see and the RDF sees but others may have alternative preferences.
