Analog Sky debuted the beta prototype of its Drifter 200mm binoculars at Oregon Star Party 2019. Attendees were excited by its features during the day and stunned by the images at night.

Read the OSP report at https://analogsky.co...d-beta-drifter/ and get to know some of the new features of the Drifter, like 10 second eyepiece and filter swapping, intuitive IPD adjustment, 2.2 degree wide fields, 60 second setup, compact form factor, custom mount and pier, and zero collimation protocol.

Hi Ricky, the retail is still being determined over the next couple months while mount/pier components are being finalized. There will be an opportunity for beta testers to buy in at an attractive discount that will be announced with the crowdfunding campaign.

Hi Garret, here's a closeup on the tertiary mirror mount:

The primary and secondary collimation don't move, so any image merging issues are resolved here under the eyepiece. Bruce Sayre as far as I know was the first person to put a kinematic mount under one tertiary mirror for this purpose. I found it helps a lot to have one under each tertiary so each side can adjust a bit to meet the other in the middle. This way, you're not moving one tertiary so far that collimation suffers.
