M31 Andromeda Galaxy Ultraportable 2

The Andromeda Galaxy is the closest galaxy to our Milky Way at 2.5 million LY distance and it contains about a trillion stars. Visible to the naked eye from dark sites, it requires a small telescope or binoculars to be spotted from typical suburbs.

 

First light for a focal reducer/flattener specific to my Borg 55FL lens as part of my exploration of ultraportable systems for urban astronomy.
