This is mounted atop my CGEM 8" Edge HD with an SBIG SG-4 autoguider attached. Finally, it functions adequately but getting there was traumatic. The first scope arrived with shredded bags of parts and crushed internal packing (Celestron's not Adorama's). My guess is that it shipped from the factory inadequately packed. Concerned for hidden internal damage, I returned it, totally hassle free, to Adorama for a replacement. The replacement (my current scope) arrived with many fittings rusty, but observing season was going to waste so I kept it. The focuser is manufactured with such slop in it that even when fully locked down the autoguider is not stable enough to function properly. I disassembled the focuser and snugged it up by inserting four long glides made of surgical tape. It now works okay but my overall opinion is that at this price, Celestron just has no concern at all for what comes out of the plant in China. You get what you pay for. I paid for and got a cheap guidescope. If I had it to do over, I'd look at other options.
