Re: (IAAC) Eye vs CCD
Hello, Nick - hope your holiday was a good one!
Please forgive my reposting your message to -announce without permission, by
the way... I expect public response will be quite positive though!
I think this would be an extremely interesting project to pursue... It really
would require some dedication however, as using any sort of light source
(including LEDs) in between observations might invalidate results.
In compensation though, spending a whole hour on the same deeply detailed
object may prove a breakthrough observing experience for many of us!
As for objects, I might actually suggest a galaxy field, if the experiment is
to be performed in Spring or Fall: the advantage would be several objects in
the same FOV, revealing a wide range of details; also a fainter group might
still represent a challenge after an hour. In early Summer sky, Abell 2151 in
Hercules might be suitable for a test with a larger instrument.
At the opposite extreme (and perhaps more humane for an hour-long observing
run!), would be an extremely bright object, such as M8, M31, or M17. Logging
the details of each observation might prove the hardest part of the experiment
however: not everyone is as skilled at sketching as you! Also, it must be near
impossible to sketch at the eyepiece without any light source. Perhaps a
standard verbal logging scheme could be adopted for tape recording?
