I have a straight through 8 x 50 finder and a Telrad. I use the Telrad to get me in the right area and then use the finder. I use both eyes with the finder to centre what ever the target object is. Some of my friends have right angle finders but I would much prefer the straight through variety, as then you can use both eyes to centre the object.

I do have a portable scope that I take out in the field and it has an 8 x 50 straight through finder and a red dot finder that I use in a similar vane to the main scope in my observatory
