really happy with service and item

Used this in my SW BD 150mm Maksutov..thinking it would be used as a finder EP ONLY..WELL I was wrong its MUCH better than that so EASY to look through with glasses, and sharp aross near all the field at f13 with 2 inch diagonal . TWIST UP eyeguard.....very pleasing indeed..would give it 5 stars except some light fall of at edges..but 1.4 DEGREES IN A MAK..WOW..Who needs a finder!

I bought this eyepiece to work with a red dot finder on my 12" Dobsonian, and am happy to say that together they give the quickest, most hassle-free finding that I have ever used.
However, the eyepiece is not edge to edge sharp. More than about two thirds from the centre, stars are noticeably blurred. So if you are looking for crisp panoramic views of the milky way, unfortunately you may have to dig a bit deeper into you pocket!
