Setting Up The Finder on an EQ Mount
Aligning the Finder on an Equatorial Mount
When setting up your telescope on your equatorial mount, aligning the Finder is an important step. (Here is a separate article on aligning the finder).
I mention this topic separately here, in the equatorial article, in order to add this advice:
Aligning your finder is much easier if you point at an object that is not moving. A distant building, telephone pole, or mountain is great in daylight. At night, Polaris is great for aligning the finder since it doesn't move.
However, it's quite difficult to get a polar-aligned equatorial mount to point the telescope at Polaris. Not impossible, just hard work. (Try it once and you'll understand.)
So, I eventually realized that if I'm setting up at night, it makes much more sense to point the telescope at Polaris and align the finder before I do the polar alignment. I start with the mount deliberately not polar aligned -- like 30 degrees off or more. Then it is easy to point at Polaris and align the finder. Then I move the mount and do the polar alignment.
