I am selling a 4" F/15 single red lens scope that is powder coated white. I have $2300 into, but will let it go for $800. It would be a nice addition to an observatory with a H-alpha filter or a science project. It comes with a homemade PVC case. Note the H-alpha filter, tripod, and dove tail and rings has been sold. Thank you, Richard

Re: 4" single red lens F/15 solar scope
Red lens? An ERF I suppose?
I bet the color correction is really good. That long focal ratio should see to that. I already have a 4" F10 refractor. If not for that I would consider this one. I do like classic scopes like this.
