[APML] Stacking the right negatives

[Alan Voetsch <critter12952@yahoo.com>]

Hi all,

Later tonight, or tomorrow I will be attempting my
first stack, yep still a virgin. :-)

I know with an obnject like M42 it's wise to have a
wide range of exposures in your negs, 2 minutes, 5
minutes, 45 minutes as an example. With the typical
DSO, say the HH, would this strategy be entirely
different? Would 2 two hour shots be preferable to a 1
hour and a 3 hour shot? These are just examples, but
you get my drift. Are we better off with 2 of about
the same exposure, or two that are somewhat different?
Why, or why not?

Thanks,
Alan
