Howdy all,

I currently use cooled CCD cameras and DSLR's for my astrophotography, but have recently been very curious about trying a 4x5 film camera for some widefield work. I have shot 35mm film and have some limited darkroom experience (many years ago), but I know nothing about the 4x5 format.

I am looking for any information about the step-by-step work flow of this format, and any particulars regarding its use in astrophotography (i.e. I have heard about vacuum backs to keep the film flat, etc.).

Any pointers and/or links to appropriate sites are greatly appreciated -- thanks!
