This study investigated the application of optical image enhancement techniques to improve astronomical photographs. The techniques tested were integration printing and spatial filtering. Each integration printing test combined several negatives of the galaxy M51 taken with the CMU 35-cm telescope into a single transparency, called the interpositive. As employed, the integration printing system required a unique design for the registration system which permitted the production of the interpositive without enlarging the image. Compared to direct integration printing, this system produces an integrated image that permits further image enhancement. The test results showed reduced grain noise, improved limiting magnitude and improved aesthetics. The spatial filtering tests used both the best interpositive of M51 and two commercial slides of galaxies. These tests were intended to enhance edges in the images. The results from the interpositive proved inconclusive due to insufficient detail, but the more detailed commercial slides yielded significant edge enhancements.
