My Hadley Telescope has a basic finder that is 3D printed. It works ok but it lacks the ability to be fine tuned.
I decided to upgrade and get a professional finder – The Celestron Starpointer.
This finder can do the following:
- Adjust left and right
- Adjust up and down
- Project a laser image retical with circle
The retical is not a dot, it’s a circle. This is useful since a dot would block the star you are trying to see. With a circle, you can point the telescope to the center and still see what you are looking at.
I designed and printed out a mount that work with the Hadely.
You can download it here.
There are no supports needed but you may need to scale it down. I increased the size to work with my printer and my telescope.
Mount Attachment To The Hadley
Insert #10 nuts into the two slots and then thread in #10 machine screws. The length should be around 1″
What I liked About It
I love the micro fine up and down adjustment. This made the whole process easy. You can adjust as necessary on a bigger object like Jupiter, then you can find smaller objects like Saturn easier than ever before.
What Could Be Improved
There is a switch on the side that turns the laser on. It also increases or decreases the brightness. I find myself forgetting to turn the laser off. There is no auto off feature. If left unchecked, it will drain the batteries if you forget as I did.
