Re: [APML] Copygraph finished and hypering Q

["Brian Larmay" <astrobri@ameritech.net>]

Thanks Clay,

I tried it out on the moon tonight but I think I overexposed the tech pan
and Im not about to waste my HC-110
The shutter was open for about 4 secs.
I forgot how to determine the focal length though...this was mentioned to me
awhile back but I cant find the exact post in the archives.
It says 280mm f 1:4.5

Can you determine the correct exposure?
Im almost positive the TP is rated 125, but what about considering the
hypersensitization.
Hypering ups the speed right?

Thanks Brian
