Re: Thoughts on wide-field film astrophotography

LT,
Thanks for your thoughts. That was kind of what I was after. For wide field astrophotography medium format film blows away digital for color representation and resolution. Perhaps DSLR's have great resolution for other forms of photography, including prime focus astrophotography, but my main focus was on wide-field astro work. I can't find photos on the net taken with DSLR's that surpass what I and others have done with p67 (or other MF equipment) and wide angle to short telephoto lenses, ie 55mm, 75mm, 90mm, 105mm, 165mm, 200mm......
That is why I have gone down the medium format film path. The work of Thomas "Wade" Earle, Dave Kodama, and others have convinced me of films prowess. They have built a path for others to follow and I like where it goes!
I to like the looks of a transparency, but a "properly" exposed image will look a little washed out if your exposing and processing for best performance on the scanner. I expose 40 minutes at f/4 or longer and then push 2 stops. This method pulls all the detail I can out of film. Such transparencies are not very good to look at by eye however.
Thanks again.
Jim
