- Orion Premium Binoviewer
- night-vision loss
Easy to assemble and use. However, very little movement is needed to effect a large change in transmission, so it could be fiddly for some, especially with gloves. The first use was with the Orion Premium Binoviewer on a 7" Mak-Cass at the Moon. Wow - what a sight - and no more night-vision loss with this little gem. It does what it says, just as it should.
