Maybe... this is the last test observation of the "veranda obs." this winter.
This winter, I was testing FCT-100, FCT-125, e-180, RC10 inch and 10 inch NEWT.
The "Veranda Obs." have so many pros and cons.
poor seeing is the worst condition... and others are not so bad.
Most of all, I'll try to test observation at every (clear) night.
This winter(Dec. 2021~Feb. 2022), I was 27 nights observation at veranda. Wow~~
Reducer, flattener BFL optimization, and Camera+filter wheel matching... and Optical collimation!!! ... etc.
Spring will come... Let's go to the field!!!
