Binocular sky window

Hi everyone,

I was just wondering if anyone has ever built a binocular sky window?

What I'm talking about can be seen at www.astro-engineering.com/Binocular%20Mo...rmountin.html#mirror and www.tricomachine.com/skywindow/ (there's a review at www.backyard-astro.com/equipment/skywindow.html ). I see ScopesnSkies in the UK sell a system called Binoflex but it seems to be out of stock at the moment.

I like the idea of being able to sit down with a pad to take notes. After considering a parallelogram mount I think there's merit to the sky window system.

I might source a front surface mirror from www.scientificmirrors.co.uk/Autocue-FSmirrors.html and have a bash at building something over the next few weeks.

All the best,

John

I have one John. When we meet up at Christmas you can have it. I wasn't mad about the optical quality to be honest.

Interesting piece of kit... daft-looking, but interesting.

There's a Belgan chap by the name of Rony on Cloudynights who reproduces his binocular sketches using a Trico Machine Sky Window , see here:

I would imagine that it's very comfortable on the neck. I have a parallelogram mount and looking at the zenith produces neck strain after a time. Lying down it's a pleasure though.
