RE: [APML] The faintest object
I was able to reach mag 20.5 with tech pan and an hour exposure with my 12.5
inch f/5 in the past. With CCD, its two mags fainter for the same exposure.

Subject: [APML] The faintest object
I read in another ML a thread about the limit magnitude with amatorial
scopes and CCD.
But with the film?
With amatorial scopes as a 20/25 cm newtonian and a film like Kodak TP2415
Hyper what is the limite magnitude I can reach?
I know that the sky is very important but, for example, in a dark sky with
naked eye magnitude 6,5?
Clear skies
