These lenses outperform most spotting scopes and achromatic doublet telescopes of similar aperture, showing details which just aren't resolved with smaller apertures
This 2-element binocular offers huge light grasp and extremely high contrast thanks to an achromatic air-gap doublet lens design.
Imagine the light gathering power of two 4" spotting scopes - one for each eye! Use your favourite 1.25" astro eyepieces for daytime nature viewing, or lunar and deepsky observation. You can even use Altair 1.25" City Light Suppression CLS filters, which isn't possible with normal binoculars.
The included 18mm Ultra-flat eyepieces give a 65° field of view, and the overall brightness of the images is quite surprising compared with using binoviewers in a 100mm telescope with the same aperture, because each eye get's 100% of the light from 100mm aperture objective lens.
The 1.25" self-centering eyepiece holder focal position allows most eyepieces to come to focus including Altair Astro, Tele Vue Delos, Nagler, Panoptic, and the Docter 12.5 mm UWA. Of course you can also use standard 1.25" astronomy filters on the eyepieces to enhance viewing even more.
Every binocular has collimation checked before shipping.
Mounting the binoculars:
For terrestrial use and casual astronomical use we recommend a large video and or camera tripod. We recommend the Altair Sabre mount with vixen clamps and Heavy Duty L-Bracket for more serious or extended observation especially at higher powers. The ultimated solution would be the iOptron AZ PRO mount. Our optional single-arm binocular mount is also available. (Code: BINOMOUNT1).
