Re: [APML] Old Kodak E100S Found

It may be ok.   It may not.

Here is how to calculate whether or not to use it:

1. Your level of experience... are you just going to be using it to debug 
your setup, test your focusing skills maybe, test tracking, learn the 
craft?  Then use it.

2. If you are at advanced level, or if you are traveling hundreds or 
thousands of miles to a true dark sky site, then do NOT use it.

3. If you think you have a really good chance at getting some really good 
pictures, and you think you are going to spend 15 hours of exposure time on 
it, then you would be crazy to use it.

4. Count the number of hours of your time you already have invested in 
learning your astrophotographic skills.

Count the amount of money you have invested in your telescope, 
astrophotographic and computer equipment.

Count the number of hours you will spend traveling to a dark site.

Count the number of hours you will spend setting up, focusing, and guiding 
the photos.

Count the number of hours you will spend processing the shot images on your 
computer.

Multiply these total hours by how much you make an hour at your day job.

Now, compare that number you come up with to the cost of a new roll of film 
and processing.  Maybe $20 total.

Ask yourself if your total investment, or even just your specific 
investment for that night is worth saving $20 for new film. For instance, 
how much will you spend just in gas getting there?

5. Ask yourself if your pictures don't come out at all, and you had the 
chance to go back and get them to come out, would you spend $20 for that?

Personally, except for number one, I think it is extremely foolish 
economics to use questionable film when film is just about the single 
cheapest thing involved in the hobby!
