William Optics Dielectric 1,25'

Review by Mik on 22.01.2014 15:27:06

My current Diagonal from Celestron crack at the eyepiece which I was a little disgusted about but it was quite old. Any how I bought this one. Delivery was spot on time with UPS. I took it out of the box and was very happy to find how heavy it felt. It is extremely well made and the optics also match the build quality.
I look forward to trying this out, if for any reason there is a problem I will add to this review.
So far worth every cent.
