Imaging with Large
Format Camera's
.Imaging with a 35mm camera is inexpensive, and very
rewarding, however the negative size is small One way of increasing
the size of the Sky you can cover,and maintain resolution is to
use a larger format. There have been many a camera made from old
aerial reconnaissance lenses, and many years ago I made one using
an old Rank Taylor Hobson lens. I was still at school, but it
did seem to work very well. I used it for meteor work with TRI
X, and Royal X Pan. No that shows my age doesn't it. Id mange
some quite pleasing results though I do not appear to have the
pictures now.
Here is the beast complete
with Polaroid land film back. The is intended to aid colour correction,
but I only used it the twilight whilst chasing Fireballs - unsuccessfully
I might add.
I have a new project
- semi back burnered at present to build something similar using
a lens I acquired from the US. Combining this with a bit of engineering
- Are you paying attention Dave Rose?, I hope to create a small
wide field imaging system.

I have acquired an
old Meade LX10 fork system and hope to mount the completed camera
in that. It would be nice to get some colour transparency shots
from a dark sky of the milky way, but we shall see.
