Vince,

Thank you. I used a Minolta (obviously) Maxxum7 with a Minolta 500mm f/8 reflex lens. I setup on a tripod in an area with a clear field of view and took my first sighting by putting the moon in a corner. I then watched which direction the moon moved and adjusted the corner to start in to match the moon's motion. I put the camera in multiple exposure mode and took the M1 picture in the corner. I then used a watch to take a new photo ever 5 minutes. Two things that need to be kept in mind is to make sure you adjust exposure as the phase of the eclipse changes and to start a new frame when you reposition to the corner for the next series. Some of the other things I did was to shot an exposure every minute and I shot multiple exposures with my 50mm lens which I then switched back to the 500mm lens for the final exposure. The final experiment I tried was to put the camera on bulb and multiple exposure, lock the shutter open for 5 minutes, wait a minute, shot a new exposure, then lock the camera open in bulb again.

I got lucky, the one photo that has two moon shots overlayed on another two was an accident where I forget to restart the frame. It turned out kind of cool so I cropped and used it. I used 100 speed fuji film used the following guide for exposure. I found this guide on the internet and printed it the day of the eclipse but can't seem to find the link any more.

f/8 100 speed film:

full moon 1/250s
25% eclipse 1/125s
50% eclipse 1/60s
75% eclipse 1/30s
full eclipse depending on brightness ranges from 4 sec. to 1 minute.

I used both 4 and 6 second exposures at full eclipse. I also adjusted down a stop for a thin cloud cover early in the eclipse.

Robin,
These are exciting - what equipment and technique for time laps did you use?
