Good, works well.
Its a no frills polar scope, nothing more nothing less. Why it is not aligned in the factory is beyond me, it is an absolute PAIN to mess with the little hex key set screws that align the scope to your RA axis. Major downer. Also the lack of illumination makes it next to impossible to see the reticle in the dark. Had to shine a flashlight into the from just to see where to put Polaris. Have the same issue with the polar scope on my AVX mount I own now. Wish there was an aftermarket solution to these Celestron polar scopes.
I bought the Celestron Polar Alignment Scope a couple weeks ago and I had it installed within 30 minutes. Aligning the scope to the rotation axis is very important and that only took ten minutes. It has made a big difference in the reliability of my polar alignment and the results of my astrophotography in the field.
Easy to install but not to align. Celestron's instructions are simply inadequate.
Easy to install, this would be a good piece of equipment if you could see the etching in the dark. Needs to be illuminated.
