Finderscope Extender

I built this because I was finding that particularly at certain angles (pointing straight up for example), there was not enough room between telescope and finderscope to be able to get my eye to it properly, and an inch or two taller helps a lot.

Also since I'm into astrophotography and have a guidescope mounted on top of my main scope which peers through between the focuser tube and the finderscope, that putting in a 15 degree tilt to the extender gives the guidescope a lot more viewing room
