SW 9x50 finder

It is straight thru and awkward. Would be ideal if I could unscrew the straight thru EP, (it does unscrew) and put a RACI in there. I've looked but don't think any I have seen are suitable, are there any?

I am sure I saw a post where somebody had DIY'd one but cannot find it now....maybe I just toss it, can't use as is!

Thanks.

You would need to shorten the tube to accommodate the added optical path length of the Amici prism.  It's probably simpler and cheaper to sell the straight through finder on the classifieds and buy a new or used RACI.

What Louis said.... Just replace it.

Thanks for replies. Just hate being wasteful.

It won't be wasted since these things are great adapted into guiders, some imager will use it.

If you're using a refractor or CAT, then a right-angled finder will be much more pleasant to use than a straight through version. Some prefer a RACI for a correct view, but I just use a right-angled finder which gives me the same view as I get through my scope with a diagonal. Straight through finders are for tube mounting on reflectors and I am amazed at how few right-angled finders are actually produced. Come on Takahashi/Vixen guys, we need right-angled finders!!!!

Yes, I’ve always thought that a much better place for a straight through finder on a refractor or SCT is at the objective end of the tube, not the eyepiece end. It’s always seemed strange to see long refractors supplied with a straight through finder right next to the eyepiece. I have found right angled finders have their disadvantages too, in that you also need a red dot finder to orient yourself, whereas straight through finder you don’t.

Well somewhere down the line I fancy giving imaging a go. I will now search for how to adapt it! Thanks.
