The exposure times listed here should be used as a starting point. Always
make exposures that are longer and shorter than the recommended time.
Also, try bracketing your exposures, taking a few photos at each shutter
speed. This will ensure that you will get a good photo.
If using black and white film, try a yellow filter to reduce the light intensity
and to increase contrast.
Keep accurate records of your exposures. This information is useful if you
want to repeat your results or if you want to submit some of your photos to
various astronomy magazines for possible publication!
This technique is also used for photographing the Sun with the proper
Celestron solar filter.
