This is a study, well made, high quality product. An amazing upgrade to the flimsy, overly touchy SW latitude base - worth every penny.
Solid upgrade for IOptron
Great build, nice to work. functions smoothly, looks great. It does not have the problem of original IOptron base, which shifts when one tightens the locking screws. It is a joy to operate. However, the angular ruler is off. I live on latitude 47N, but after accurate polar alignment with a well leveled tripod, the marker shows consistently 43 degrees. Not a deal breaker once you know it, but for the price I would expect the markers to be more accurate, so that I do not have to fiddle with the altitude *** once I know my latitude.
Smoothly functioning mechanisms will increase accuracy of polar alignment
The William Optics ***** Style Base Mount for SkyGuider Pro is a solidly built base, with smoothly functioning mechanisms that will help speed up polar alignment and facilitate a higher degree of accuracy than is possible with the OEM SkyGuider Pro mount. Although I think this base is overpriced and I can't say it's a great value since it's so expensive, it's a very useful piece of equipment.
Quality feel -- Quality performance
I purchased the William Optics (WO) base mount as an upgrade to the mount that came with my Skywatcher Star Adventurer (SA). I use the WO mount in conjunction with the ASIair Pro to dial in my polar alignment (PA). The combination of the two is simply a delight to work with. The WO mount provides much more control over the fine adjustments necessary to get a precise PA than the Star Adventurer mount ever could. The WO base mount is more expensive than the SA, but it is decidedly worth the price difference.
If you have an Ioptron StarGuider or the Star Adventurer than you need this! Do yourself a favor and make your life easier. Buy it!
