Re: (meteorobs) Re: Holographic acetate grating spectroscopy.



Anyone know where I can get a 4X5
Negaflat cheap?  

I am not sure but how is the camera used ?
If in open air
Watch out for temperature drops and moist the plate film will plop !!!
(even on 35mm film this is a problem)
Heat the camera AND the film
