Photo by Laurence Mohr. The Bubble Nebula (Caldwell 11) located ca. 10,000 light years away in the constellation Cassiopeia. The affect of the hot central star on the surrounding hydrogen gas is clearly visible – causing the gas to glow like a neon sign and forming it into a bubble with its stellar wind. 36 exposures at 10 min each; ISO 800; EdgeHD 1100; f/7; taken in Brooklyn, Wisconsin.

The Whirlpool Galaxy (Messier 51) is a spiral galaxy located 27 million light years from us in the constellation Canes. It is interacting with a much smaller galaxy, NGC 5195. The bright blue knots visible spread along the spiral arms are regions of rapid star formation, while the dark filaments are zones of dust obscuring the light from the galaxy’s stars.

Those with sharp eyes might be able to spot at least four other spiral galaxies (most edge-on) in this image.

The Dearborn Telescope has been in the collection of the Adler Planetarium and Astronomy Museum since 1930. Considered the largest in the world when it was built, the telescope has significant historical importance to both Chicago and astronomy. This presentation will examine the telescope’s history, condition examination, and original surface recovery treatment.

Craig Deller is a Fellow of the American Institute for Conservation of Historic & Artistic Works and on the faculty of the School of the Art Institute of Chicago’s “Interior Surfaces Conservation Lab...
