Test of a new 295mm D-ERF.

Post by Valery »

Hi folks,

These images were taken yesterday's morning, April 25 2017 when I performed a third test
of a recently finished 295mm D-ERF for our Hong Kong based customer Raymond Tse.

Telescope C11 280mm F/10 SCT equipped with DS etalons. Camera Basler 1920-155.

Seeing was quite unstable and variable. However I was lucky to catch two moments of
some seeing improvements.

Hope you like these pictures.


Valery

Hi Valery...

Excellent resolution on those images...very sharp indeed :bow

Could you please expand a little on the optical setup here? What are you using as amplification optics, or is it native f10 SCT focus?

Thanks,
Brian
