Thanks guys. The film is history. What slide film is recommended for piggy-back astrophotography?
My films of choice are Ektachrome 100 and Ektachrome 400.
Also, should a shoot a roll of film in the daytime just to get used to the camera? I don't know that you need to have any film in the camera just to practice using its various functions.
I'm not familiar with the OM-2. If it has a "T" setting on the shutter speed you can get away with most any cable release (click the cable release once to start the exposure and once to end it). But if all you have is a "B" setting you will need to use a _locking_ cable release. It's also handy if you can lock the OM-2's internal mirror into the "out of the way" position before starting the exposure (that helps to avoid some vibration). Chuck's warning about airplanes is all too true. However, an approaching airplane need not ruin or shorten the exposure. As the plane approaches the camera's field of view just put a black sheet of paper in front of (but not touching) the lens. Once the plane is gone pull the paper out of the way. I've used this trick many times. Works great. Patrick
