do you have a good recommendation for a model of magnifying finderscope to replace the small finder scope on a celestron 8se.
During my search for finderscopes I found several of acceptable price and quality. However, where the variations come in is the features that you're seeking. Do you want illuminated crosshairs? Do you want a reversed image view? Some people like right-angle viewfinders - they go well with dobs and newtonians. All these cost more.
I am happy with my reversed-image, illuminated crosshair 8 X 50 viewfinder. It's by Explore Scientific and cost $169 USD. You could get a much cheaper finder though, and this one would be rather big for an 8" scope.
On the other hand, the little 6 X 30 finder on my Takahashi refractor has nothing . . . except good optics. It costs $153. And though I love it, I would hesitate to recommend it to anyone, because it's just not the best value for your money.
