William Optics Binoviewer - a Good Choice
This is a great way to get started in binoviewing. These work fine with my Celestron-11 SCT. When properly connected the magnification is around 150X with the supplied 20mm eyepieces. So not wide field, but great for smaller DSOs like globulars as well as for the Moon and planets. This is a quality product. The only small negative is the included 1.6X OCS (optical correction system) that threads into the binoviewer nosepiece is slightly smaller in diameter than 1-1/4 inch (1.22 inches). Thus the supplied cap for the nosepiece falls off when the OCS is attached. Other than that litlle problem everything has met or exceeded my expectations. I highly recommend this binoviewer.
Excellent low cost binoviewers
I researched several different binoviewers before settling on the inexpensive pair from Williams Optics. They were well packaged and look to be well made. I had no issues whatsoever using them with my C11 SCT. Views of the moon, Jupiter, Saturn, M42 and M13 were all fantastic. Can’t wait to try them with some higher quality eyepieces.
William Optics Bino
First I received my Bino with scratches. I called them and they send me a new unit at the moment they have the proof by the carrier that I sent back the defect unit. I received it three days later and I am in Canada!
Better than Advertised
I ordered these after scouring the net for info on binoviewers......their pro and cons......and decided that at this price point, why not. They arrived on time enclosed in an attractive box that had cut-outs for the two Swan eyepieces and the Barlow. First light was tonight with moderate seeing, but WOW did they perform. I was so excited to try them that I did not give them time to adjust to the night air, but it did not seem to matter, they were crystal clear right out of the box. No collimating problems, no failure to merge, no problems tightening the eyepieces, nothing but the rings of Saturn filling both my eyes in 3D!! I could see its rings and the famous Cassini division, with no false color. In the background were stars that were sharp to the edge of the nearly 70 degree FOV,. I could go on, but I think I will go out again and have another look at them through my LX 90. If you are a newbie, or a seasoned amateur who would like to take a space walk in 3D and don't want to break the bank, buy these nocs. Thanks Vinnie and the rest of the crew over there at OPT for offering such a great deal.
this binoviewer is aboslutely fantastic. in the 18 months ive had this unit i have pushed it to the limits. in 18 months i have completed 5 astronomical league clubs. viewed a few mag 13 galaxy and viewed all carbon stars, seen all 6 stars of the trapizium and quite honestly viewing anything with both eyes is a real treat everyone should try. if you have the money and desire to stop squinting with one eye and see with both eyes wide open who knows you might just find that your jaw is wide open in awwe. my suggestion is get a set and enjoy in the view. happy stargazing Greg
the craftmanship is great, planetary views are jaw dropping,rings of saturn wow, belts on jupiter WOW the moon WOOOOOOW! deep sky object a bit challenging as you lose a full magnitude, mag 10 becomes 11 and so on. but still a great view. the supplied EP are OK if you have others high power great use them. I use the WO EP and they do a good job from my light polluted area! I would recommend these to anyone! they are well made and fun for the family.
