I was having problems with the focuser on my Williams Optics Zenithstar 66 SD and decided to splurge and put a Moonlite focuser on it. The focuser cost more than I paid for the telescope, but it is really nice and high quality! I now also have a standard 2 inch focuser rather then the strange SCT threads on the old focuser.
I tried many times to adjust the old focuser and was never sure if there was something wrong with it or just my poor abilities. Whatever was going on with it, the new focuser is in a entirely different league, which you would expect given the cost.
I know this is about refractors, but the point is, it’s not overkill to want quality workmanship and fine accessories on your telescope. Case in point...I have a Orion XT8 Plus with a MoonLite CR tri-knob focuser with shift lock. When I tallied up the additional extras on the focuser and the Universal Install Kit, the total came to close to $350. Now that doesn’t seem too bad, but installing it on a telescope that cost $550 would seem insane to some. Putting an accessory that costs 2/3 or so the price of the scope would seem like a waste of money better spent on an eyepiece or another few accessories.
However, please remember this...this is NOT their scope, it is YOURS! YOU choose to do what YOU want to do to YOUR scope. I will argue to the bitter end that wanting a fine quality focuser over the stock mediocre one is money well spent, regardless how much the focuser costs compared to the telescope in question. The sheer quality and buttery smoothness of both coarse and fine focuser knobs is total luxury and the MoonLite with its universal install kit is actually lighter by a very small margin than the GSO stock focuser. The MoonLite outperforms the GSO stock focuser in pure workmanship, tight tolerances, smoothness of travel and even the color brings a nice aesthetically pleasing look to the scope now. No such thing as overkill...but there is such a thing mediocre or bad performance. Congrats and enjoy your beautiful MoonLite focuser!
