The images on this page were taken with the camera setup at the focuser and a 3.5" secondary mirror. The truss
tubes were shortened approximately 8 inches, resulting in a loss of over half the light from the 25" Galaxy Optics mirror.
NGC 4565 20 minute exposure
M1 Crab Nebula
Problem with collimation.
M74 10 minute exposure
M81 1 hour exposure
Overexposed. I'm told this image would have improved dramatically if I had used a "Flat Field".
Taken with Nikon F100 Camera.
Kodak Bright Sun 100 Film.
My knowledge of post processing is next to nothing. Guess the images can only improve from here on!
