- corrector plate
- Edge HD
- learning curve
I wish Celestron would have thought of this
These screws make collimating my Edge HD 8 easy peesy. They are easy to install and easy to use. I really like the idea that I don't have a pointy, Phillips screwdriver any where near my corrector plate!
I ordered the wrong ones of course, but they sent me a return # and I ordered knew ones. They promptly refunded me for the wrong ones. They are still a bit harder to get a hold of but much easier than a screwdriver.
