ATM Light traps for Dobsonians
Hi everyone !
Does anyone know what design criteria (Dimensions, light trap
depht, etc.) should be taken to build a light trap located on the opposite side
of the secondary mirror as seen from the focuser, like the one described in
January 2001 S&T's article "Stray Light in Telescopes" by Harold
Suiter ?. Thanks !
Best regards,
