Re: [APML] First Tricolor in 9" Schmidt

Hi Richard,
 
You have a really nice picture of the NA and Pelican Nebulas.  I wonder, did you hyper the Tech Pan with a hard vacuum first?  Your film captured a lot, but from reading the archives, Tech Pan normally takes a lot longer to hyper if the initial vacuum is not in the militorr region, like 96 hours at 50°C.  Also with the longer hyper times, the development time is shortened, more like 10 minutes.  I'm the first to say "don't mess with success", but sometimes there's some improvement possible.
 
It's great to see you are getting such good results with your current setup.

Hi , here is my first successful Tricolor in the 9" Schmidt camera.
I really like how it picks up the faint nebulosity and the fine grain of course.
I am using a Schuler  R,Gc,Bc - 48mm glass filter set.
