Yesterday evening was ideal for slowly panning through the rich starfields of Cygnus, Lyra and Casseopiea with the homemade binocular mirror-mount. Attached to the mount was the SKYMASTER 25X70 binocular.
The SKYMASTER range are not premium binoculars ( the aperture is stopped down to 63mm at the prisms on the 70mm ), but they render bright, sharp, views of the starry sky. The image is reversed in the mirror-mount, which is no big handicap, considering image inversion in a Newtonian reflector.
The advantage of the mirror-mount is the sheer comfort of use. We can sit and effortlessly wander through the night sky, free of having a stiff neck and vibrations.
There were several stellar chains in the Cygnus and Lyra regions that mimicked Kemble's Cascade. The celebrated Alberio double glowed golden yellow and blue, like contrasting gemstones. Vega blazed gloriously and the Ring Nebula was discernible as a little grey smudge.

Sounds like a good night, Brian.

I've noticed the Kemble-like asterisms in this region, trails of stars.
