A truly beautiful telescope. The overall build quality & finish is impossible to fault (as you’d expect from any WO product). Although I’ve only used this scope twice since purchase, I’ve immediately realised the optics are razor sharp & superior to both my previous refractors (both were doublets). This telescope really is monster sized. The focus tube is also monster sized & clearly designed for ultra stable imaging. I bought the rack & pinion focuser version & it works beautifully with a ZWO EAF. This focuser required me to set my auto-focuser direction to reverse in the software settings. I also purchased the 0.72 reducer/ flattener & although the flattener price may appear expensive, you will see why when you purchase one as the flattener is also monster sized. It’s nearly as big as a Christmas pudding !
I bought the telescope to permanently fit into a medium sized observatory (6’ x 6’) & the telescope with imaging system attached only just fits with an inch clearance behind the main camera. My pier centreline is distanced 26” from the north wall so please check you’ve got enough room for this scope
I don’t know if I’d recommend this sized scope for regular setting up in your garden due to it’s size & weight.
My EQ6 R Pro can handle & guide this scope perfectly. I’ve fitted a 3rd 5kg counter weight to avoid use of the extension bar
Overall, I’m 100% delighted with this scope & sure to purchase the other x1 field flattener soon to boost the focal length for planetary & galaxy work

This is an exceptional piece of kit. I was already familiar with a previous incarnation we bought for a school observatory, and all of the changes made to the new version make the users experience easier. This means more time is spent viewing and photographing. In Britain viewing quality is rarely better than 1", similar to the limit of resolution of this telescope, particularly with the addition of a full frame DSLR. Like much of the product range sold to amateur astronomers the instructions and manuals are written for experienced users,. New innovations such as the Lens cap with the focussing mask are often missing instructional details such as access to the mask was unscrewing part of the lid to gain access to it rather than pull apart. This is not unique to Williams Optics but they do rely too much on a collection of less than satisfactory on line users for help.. So excellent product showing a superior set of innovations that makes experience of astronomy easier and simpler, but the experience could be better if this innovation was documented better. Certainly overall it is excellent value for money.
