Harry Siebert BinoViewer 2"

Being the first to person get this two inch Bino-Viewer, all I can say is ammazing views. The views on the double cluster were out standing, but I'm still lost for words. M13 last night in the 9" APO was like I've never seen before. The flat field of view and seeing M13 with both eyes was WOW!!. Using this bino-viewer I've noticed that M2 and M13 resolved at lower powers than when using a single eyepice. The outer region's of M2 were resolved using the Siebert 32mm Ultra Pluse two inchers at a power of 88x in the 9" APO. At 201x the view was just mind shattering. M13 at high power ( 320x ) was resolved like I've never see in my 30+ years of observing globular clusters. The dark lanes that I've seen before in the resolved core was seen more easily and in more contrast. The chain star that run up through the core to the outer regions, stood out in 3D form. The view of M8 was jaw dropping. Nebulosity regions were seen easily and had more contrast than with a single eyepiece. I only hope that Bino-Viewer #2 that Todd Gross will get to review is as good as mine.
note: Two inch Bino-Viewers are a big step up from 1 1/4" ones, that mainly work great on the planets. These two inch bino-viewers so far have worked flawlessly on everything from Neb's, Open Clusters and Globular Clusters. As soon as the gas gaints are up all night, I'll be getting no sleep at all.

I would like to make some remarks to my post above. I do not want anyone to feel that I'm trying to say that 1 1/4" bino-viewers are only good for planetary observing. I have tried my Tele Vue units on deep sky objects, and find that they do good on brighter deep sky objects. But they have only 26mm optics, where as, the Siebert two inch Bino-Viewer unit has 40mm optics. Because of the 40mm optics I see much brighter objects and more sharper images with more contrast, on objects of 8th mag. and fainter. A more indepth review well be posted soon. I've used the two inch unit in a 9"APO, 6"APO, 6" Archromat, 10" SCT, 8" SCT, and a 16" SCT. I only put up this short review to let everyone know how the unit is working so far.
