The telescope that came with the Citizen CATE Experiment (2017 solar imaging project in conjunction with the National Solar Observatory) did not have a finder scope, though it did have a solar finder as part of the equipment.
The lack of a nighttime finder made the scope barely useful for night sky observation.
I contacted Daystar (the manufacturer of the scope) about this but received a useless response, as if someone didn't bother to read my email.
I wanted something like a Telrad finder but the footprint of that finder was far too large for the body of the Daystar scope.
So after doing some internet searching I found the Rigel Systems Quick Finder 1X Finder R-CRS.
It comes with two bases so that one can have a base on two different telescopes and move the finder from one telescope to another without a problem.
It is "tall" which means it is easier to get your head in a good position to see through the finder and locate the object of your choice.
The LED "heads up" display has two concentric circles and a knob that you can use to adjust the brightness of them. There is another knob that allows you to control the "flashing" rate of the circles, it gets them out of the way briefly so you can see your target easier.
The three white knobs are to adjust the angle of the circles to your scope.
The process is an easy one:
* find some object far away that you can see easily with your scope (I used the Moon)
* turn on the finder.
* adjust the brightness and flashing rate.
* then using the three knobs bring the circles to center on your object.
Done!
By the way, ALWAYS turn off the finder to preserve the replaceable internal battery of the finder.
It is a good idea to keep a few of the 3 volt button batteries on hand (found at almost all stores).
