M-31

M-31 (NGC 224) Andromeda Galaxy - 1.5 hour exposure was taken on 103aD film by Bill Benton from the University of Southern California on the SRO 0.76m reflector in 1973.

In the 1920's, Edwin Hubble studied Cepheid variable stars in this galaxy while working at the Mount Wilson Observatory. It was his observations that enabled an accurate measurement of the distance from Earth to M-31.

 

 

 

 

M-33

This photograph of M-33 illustrates the full, un-vignetted, field of the 30-inch telescope to be just over 1 degree.

This image was made using a 4x5-inch camera mounted at the prime focus.

The 20-minute exposure was made on Oct 21, 1963 and represents one of the earliest pictures we have that was taken through the telescope.

 

 

 

 

 

 

 

 

 

NGC 3887
Located in the constellation Crater (the Cup), this galaxy is of a type called a "barred-spiral." A central bar appears to stretch across the center of the galaxy, with two predominent spiral arms attached to each end. Numerous bright areas in the spiral arms are clouds of hydrogen gas where new stars are formed.
This image was made from 9 1-minute exposures using the Stony Ridge 0.76-m f/6 telescope and Apogee AP8 camera during the Faint Object Follow Up program.

 

NGC 1055
Located in the constellation Cetus the Whale.
0.76-m f/6, ST6, 20 minutes (combination of four 5-minute integrations, V filter
