Full moon at f/6.3 (using a focal
reducer) on Mitsubishi ISO 100 film. Exposure time is 1/250th second.
The moon is upside down (too lazy
to correct the image).
Crescent moon at f/10 (prime focus)
on Mitsubishi ISO 100 film. Exposure time is 1/125th second.
The actual picture is much nicer.
Crater Theophilus (big one at lower
right with a hill in the middle) and Cyrillus (adjacent to Theophilus with
two hills in the middle of it)
at f/80 using eyepiece projection (using a 7mm UO ortho) on Mitsubishi
ISO
100 film. Exposure time is
1 second. Subsequent pictures were also taken with exposures
of 2-10 seconds
and all were fuzzier with decreasing
resolution with increasing exposure time. Because of this, I suspect
that focus is not the reason for
the fuzziness (as my wife does), but atmoshperic turbulence is the culprit
.
I would like to try more pictures
with faster film to see if the resolution is increased. The angular
distance
between the two hills in the crater
Cyrillus is about 5 arc seconds. Ideally, the scope can resolve 0.465".
I dont expect to ever get this
in practice, but increasing the resolution to 1 or 2 " should be attainable.

Aurora in Tucson! The bright
sun-like-object is actually a very overexposed crescent moon.
The
constellation in this picture is
Auriga. The center of the picture is directed to the Northwest, right
is north
and left is looking more west.
This picture was taken with a 50mm lens at f/2.8 with an exposure time
of
45 seconds on Mitsubishi ISO 100
film. If more Aurora occured in Tucson I would reduce the exposure
time on subsequent pictures!
