hi guys,
anyone have any experience with the UWA eyepieces?
they are the cheapest 82 degree EPs we have here in SA, but you get what you pay for in this hobby...

If you are talking about the Uwan series I had a 7mm and found it to be on par with a 7mm T6 Nagler or pretty darned close to it's performance.I preferred the Nagler because of it's ergonomics and the fact that at the time I was building a Nagler collection.

I owned the 28 and 16mm UWANs and they are great eyepieces. Some people have complained about the flat top but once you are used to it it's not an issue. Best bang for the buck ultra wides imo.

I have the set and find them to be very high quality. I use the 3 higher powers in my refractor and the 28 is a good match for my SCT. As mentioned earlier some people do not like the push up eyecups but I do not mind them at all, they seem to fit me very well. Some people have even changed the cups out for rubber eye cups without much trouble. I would highly reccomend them.

My 7mm UWAN gives great views of globs, galaxies, and is the perfect Jupiter ep for my scope. No complaints here,a welcome addition to my collection. I like large FOV's for using averted vision as you can look away easier.

One thing you may want to consider is that there has been strong speculation from several sources that the 7 mm UWAN is actually an 8 mm eyepiece.

I was wondering why the views of my 9mm and 7mm looked very close, Lawrence. Now I got that ep yahtzee game feeling.

I have the 16mm UWAN, I bought it to see if they were as good as I hear. I am going to order the other three, and that should answer the question how good I think they are. Unfortunately there are only four in the series and that's been the case since they were released.
Only downside (if you consider it as such) is that you won't get cheers and pats on the shoulder from all the TV fanboys on this board when you buy one, but if you can live with that it's nagler quality at 2/3 the price.

I see several byas's on this board. I will describe them as I see them.
First is the Televue Snob's - These people seem to believe that televue is the gospel. To own anything but Televue is to be unclean. They preach that we must all repent and convert to the one true optics diety, Al.
Second, the any premium but Televue crowd - These people will hype all premium brands of equipment as being just as good or better than Televue. These people are the cast outs from the church of Televue and preach that a step down the path of Televue is a path to the dark side with no hope of redemption once that path has been tread upon.
Third, the budget aware crowd - These people will be quite happy with any eyepiece that gives them 80-90% of the premium performance with half the cost. They search for the best bang for buck. Most people fall into this catagory. Some in this crowd curse those in the Televue crowd for their wanton spending habits. Many wish to join one of the religions, to either worship at the Televue alter or to worship from the anti-televue alter but their thriftyness keeps them from taking that next step into the wide field light.
Fourth, The questers for the zero glass eyepiece - These people believe that no matter how narrow the field of view or how little eye relief the eyepiece has it is worth it to get less glass in the optical path. Any amount of glass more than nothing is hampering the view so they must have the least amount of glass possible. Strangely, many of these people will curse an extra lens in the eyepiece but drool over an extra lens in their objective, especially if it's an expensive type of glass in a triplet objective. They quest for ever higher powers for planetary observation by using antiquated eyepiece designs but bulk at the thought of a long focal length objective to elliminate spurious color because by simply adding another glass to the recipe for the objective they can achieve the same performance in a shorter tube.
So what is the one true path?
Is there a way to avoid the pitfalls that await us in the quest for the perfect eyepiece?
No one knows... The paths the astronomer treads down are indeed full of as much mystery, wonder, and danger as is the universe the astronomer seeks to understand.
I wish you luck on your quest for the perfect eyepiece.

Hey Daren, perhaps you posted to the wrong thread. All I've read here so far are positive assessments for the UWANs.

It's a pity they never came out with more eps in the series though. The four focal lengths are spread a bit thin for most to be happy. Just two or three more fl's would be great (say 5, 10, 21 or so).

Yup, I've felt the same way for a long time. If I recall, when they came out with the line they were going to see how it did before adding more fls. It has done extremely well but there have sadly been no additions.

My theory is that the profit margin on these eyepieces is very slim and that William Optics consider them something of a status product ("look what we can do"-type of thing). I have no evidence to back that up, but since they seem to have done well, I can't think of another reason why they wouldn't have released more of them if they were really making them good money.
