I'm curious about this eyepiece. Is there any way to remove the twist top  so that it doesn't sit there overly LARGE for your eye socket?

 

I'm thinking that it can be removed because the twist top of the 28mm WO UWAN can be removed.

 

Anybody know?

Looks the same as APM XWA. If you mean the rubber eyeguard, they are removable on APM's revealing some threads.

They are much different. The 9mm William Optics has a very different eye cup.

Maybe because they felt the ONE EXTRA degree was not worth it ?

Just got back from a short drive. I picked up a 9mm William Optics 101 degree eyepiece. Feels comfortable to the eye actually, which I did not expect. Eye relief feels very good and even longer than my 13mm APM 100 degree.

William Optics seems to like to add 1 or 2 to everything.. 

 

This a good example... I don't like it, it has caused me to distrust them and I've pretty much crossed them off my list.. I really like my ~2004 80 mm F/7 Megrez ll FD but even then it was misleading. The objective cell has Fluorite written on it but it's actually FPL-53.

 

I knew that when I bought it but not every one did..

The eyepiece WO made is exactly the same as the Skywatcher Myriad. I didn't care if it said "101 degree" on the side, because I knew it would be exactly like the Myriad.

 

I picked it up and I am glad I did instead of having to wait longer for the APM stock, which may not be here at anytime soon.

 

The bonus of buying the WO version was that the eye lens is flush with the top which gives it just a bit more eye relief than the APM's. I then removed the twist up rubber eye cup and it's even more immersive now.

 

Excellent grab IMO.

The ER feels a tad longer then both my 20mm and 13mm APM's.

 

So, big BONUS there. waytogo.gif

After using my Baader Morpheus eyepieces, and going back to the 100 degree ones, it was really noticeable how BIG the apparent field of view was in my 100's. I still have the 6.5mm Baader Morpheus, which I use on Jupiter, and will also for Mars.

 

The 9mm WO did good on Saturn because it isn't as bright as Jupiter. I barlowed the 9mm William Optics 100 degree and it worked great on Saturn at 240x with the added drift time.

I just dislike gimmicks and misrepresentation.  Yes, it's a small thing and I would buy one if there was a used one locally and the price was right.

 

But they do it with their refractors, add a mm to the aperture.. it's a bad habit.. It's not like what they did 15 years ago, calling a FPL-53 Doublet Fluorite, but I am disappointed in them, they can do better.
