Haven't used them yet
I was hesitant at first after reading some of the comments. Once I received it I followed the supplied instructions and it only took about 15 mikes to install and align it with my AVX mount. It wasn't as bad as it was put out there to be. That night I had no issues polar aligning. No...it doesn't have a light but you can't beat it for the price. Just have patience. Keep looking up.
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. Wish there was an aftermarket solution to these Celestron polar scopes. Thankfully I only use it for a rough polar alignment. Then I complete my polar align using either SharpCap or the All-Star Polar Align in my Hand Controller.
Seems to be a very good quality item which adapted well to my homebuilt mount and arrived very quickly.
This finder makes polar alignment a breeze. While the CGEM mount is quite capable in this by itself the addition of the scope pretty much guarantees it. Packaging and shipment was right on and ease of set up and use really simple. I have not needed a lit etching for the location of Polaris as the star is quite bright through it, even before it's full dark.Great product, OPT!
Aligning the reticle was a nightmare with the hex screws. I swapped them out with thumb screws and it literally takes less than 5 minutes to align now. It's a shame they didn't think about the end user in this regard, the hex screws really are not enough when adjusting to keep the reticle from falling in the scope housing, easier to keep tension on the reticle with thumbscrews so that you can tighten as you loosen. But, the scope does what it was designed to do, polar alignment is easy as pie wit this little guy--once it has been aligned, that is.
