First, to ask for excuses for my limited English. I am Spanish and I it do not dominate too much good. When I decided to change of erecting prism of 1,25 " to 2 ", immediately I decided for WO 2? 45º erecting prism. The reasons for this decision, it is based that on having had a few ocular heavy (LVW) with almost 500 grs, needed a erecting prism robustly and of quality (bak 4). WO offered me this possibility. Besides, it had an adapter of 2 " to 1,25 " with what I did not need to acquire it separately. As for the functioning, to say that I am totally satisfied.. So much in terrestrial as astronomic use, chord works to its characteristics. Nothing of reflexes and estimates notable decrease of the luminosity. The inconvenient only one that I it see is that, due to its great size, with some telescopes and eyepieces, it will give problems of approach. Besides this disadvantage, I do not see any any more. It is in the line of the products WO (optical good and mechanical quality and excellent aesthetics). Sincerely, I recommend it, especially for terrestrial use. Congratulation for the accessory.
