I've always used straight-through finders and just cannot get used to right angle jobs, mind you mine are not corrected but that isn't the problem. With a straight-through you can look at the sky with both eyes, one naked eye and the other at the finder. After a bit of practice you will merge the images and perceive the cross hairs in the finder projected onto the sky at zero power. That gets you close to the object (often very close) and then you close one eye and use the finder alone. You can't get that convenience with a right-angle finder. Then there is the whole image flip issue to deal with.
I used to do that with my old 10" f/8 on a eq mount where the finder was a long way off the ground. I was also much younger then and could bend and twist into strange positions (not all of them in parked cars
). Now with shorter scopes on dobs mounts and being older and less flexible that isn't viable for me. I'm just pointing out the possibility because many people aren't aware of the technique and so may not know to even try it.
