[APML] Stacking film images

["Bradley Hope" <bradley@thorngarden.net>]

Good morning;

I've a couple of questions concerning stacking images with film. I know
there are a couple of free stacking apps, Registax and AstroStack, which one
is better? How is the film exposed for stacking, are they fully exposed
images, or are they intentionally underexposed? Lastly, is there any real
advantage to be gained by stacking film images other than doing RGB
exposures and combining?

Thank you and clear skies
