This started out as a portrait camera. Then I got to thinking. ( trouble there  ) 210mm copy lens at f4.5. Until I can scrounge another Packard shutter, I'll just do long exposures and hat trick shots. The finder scope is to center the subject. It will be too dim on the ground glass in most cases. I've set the lens at infinity for now.   It's actually a deep navy blue. The Coolpix flash is a pain sometimes. |

Looks big enough to mount on wheels with hydraulic shocks to cushion the recoil. |

About 8" cubed. Weighs about 9 pounds. It will be on a tripod, so I don't have to carry it.  |

Will that have a true-motion drive? (Almost said a clockwork drive - stupid of me!)?

It can be used with my motorized barn door tracker.  |

Excellent!
Looks like an oven clock or washing machine timer drive. What will that give you? Even my 400mm with 2x extender only givesa smallish image of the moon,and can just make Jupiter out to be a small disc - although it's moons are bright and clear. Are you talking about the lens's aperture as being 210mm as opposed to it's focal length?

The focal length is 210mm. But being a 4X5, it will allow great enlargement without image sharpness loss.
The motor is from a time clock. It will track the stars at sidereal speed.
