I first purchased this diagonal on my last combat deployment, and used it in conjunction with a 4" Mak. The difference in views I got with the William Optics Diagonal, compared to the diagonal that was supplied with the telescope were more than noticeably better.
For DSOs using an F/14 ratio Mak, I needed all the light I could get, and this diagonal helped out quite a bit. It turned the Orion Nebula into a real treat.
The input tube is threaded for a filter, which I found to be very time saving, and the lens objective retaining ring was great. It held all my lenses firmly in place without marring the barrels.
As soon as my company gets settled in Afghanistan, I plan on purchasing this diagonal again, to use with a 180mm Mak!

These are superb binoculars. With a 7.1mm exit pupil you best have young eyes, as well. As we age, pupil maximum opening at night is reduced. At my age of 82, it is about 3mm at best. So, look to 10X50 or 12x50 binoculars. If you are 60 years old, you may most likely have 4mm eyes..

A while back, I ordered the 40mm Swan, and was extremely surprised with the eyepiece. The craftsmanship is superb. When I looked through it in my 8" LX90, I was "wowed". I then ordered all the other 2" eyepieces, as well as the 1.25" eyepieces, and the binoviewer. The craftsmanship and quality in all of these products were superb. I, like alot of people, got the Televue bug. I sold all my William Optics accessories to fund the purchase of several Naglers and Panoptics. I had 7 of them. After a few months, I sold all the Televue's and replaced all the William Optics accessories I had before. To me, these are better than the big, clunky black eyepieces with green lettering. The optics were clearer, and craftsmanship is much better. William Optics makes a superb product, I wish I could afford one of their scopes. The Swan's are excellent eyepieces, and I'd like to see them make a higher powered 2" Swan, something under 20mm. Im a William Optics viewer for life.

When I ordered this OTA I was a little bit unsure (spending almost 4,000 site unseen), but I went ahead due to William Optics reputation and order the FLT-132. Once I recieved this OTA I was relieved and impressed. The case alone shows the company's dedication to quality. The optics in this OTA is great. The workmanship on every aspect of this telescope is excellent. The focuser's rotating end piece is a nice touch; so much better than loosening the knob holding the diagonal to rotate your diagonal. The fine focus knob works great and no scope should be without one.
The first night I used this OTA I was so pleased with it. When I had a night where seeing was very good this scope really shined. The Moon at high magnification was SPECTACULAR! I use a 4mm lens through a 2x Barlow and saw the Moon like never before. Craters so small peppered the surface of the moon and small rocks looking almost like suger grains through a microscope.
All I can say is this met and exceeded everyone o..

The SWAN 33mm eyepiece is part of the WO economy priced eyepieces. While not sharp to the edge of my Megrez 80FD field of view, it does provide about 4.25 degrees of sky that is sharp out to 2/3 of the viewing circle. The build quality is excellent, like all WO products, and it serves my purposes well as a wide field low power finder eyepiece until I save up for a 28mm UWAN to go with my other UWANs. For the money it is a good value, and the tapered barrel ensures smooth insertion and removal in my 2" compression diagonal.

Comparison of 35mm Panoptic to Williams Optics 40mm 72 degree widefield.
Physical comparisons:
Televue 35mm Panoptic:
Heavier than the Williams Optics 40mm, excellent machining on the eyepiece barrel, and sharp anodizing, well cut formed and fit rubber grip. The 2? end of the eyepiece seems to be stainless or chromed steel, perhaps accounting for part of the additional weight. According to the TV website the 35mm Pan has 6 optical elements in 4 groups. Coatings apparently of two types, both distinct green and magenta colorings both on and off axis, quality of coatings excellent. Rubber eyecup extends approximately ¼ inch very flexible and caps are well fitting. I prefer the fluorescent green lettering, which is done with great accuracy.
Williams Optics 40MM:
Excellent machining, the 2? end of the eyepiece seems to be an aluminum machining, also sharply anodized, and well machined on a par with the TV. Has dual rubber grip panels, both well cut and fitted. Slightly smaller..
