Messier 95 & 96

M95 (NGC 3351) & M96 (NGC 3368) are spiral galaxies in the constellation Leo. At magnitudes 9.7 and 9.2, respectfully, they cannot be seen by naked eye. See their location below.

M95 & M96

My first attempt on March 24th was too cloudy. I increased the exposure time and waited for a more clear night and less moon on 04/14/2023.

North (toward Polaris) is up in the photo. The picture was taken with a fully modified Canon Rebel camera (this is my one shot color camera) on a TEC 140 telescope in the Alpenglow-Torrey House Observatory in the dark sky community of Torrey, Utah (Bortle 2-3). The ten best of 14 120-second sub-frames were used and stacked in Deep Sky Stacker = twenty minute photo. Unguided, binned 2X2 (to make smaller files for remote transfer), no calibration frames. Processed in Photoshop (CS5).

Messier 31

M31 (NGC 224) is a spiral galaxy in Andromeda and is our closest galaxy neighbor– the Andromeda Galaxy.

Most of M31 is in the frame below.

The picture was taken by a modified Canon Rebel on a TEC 140 in the Alpenglow Torrey House Observatory in the dark sky community of Torrey on September 25th 2022. Continue reading

Galaxy Season (and why is the night dark?)

M86 and Galaxies

M86 and galaxies, 4/11-12/2021 (click image for technical info).

Spring is galaxy season. The Milky Way winds low around the horizon leaving the thin part of the galaxy overhead making the best time to look up and out through our galaxy to other galaxies millions of light years away. The larger galaxies in this image range from 15 million to 40 million light years away. Our galaxy is estimated to be between 150,000 to 200,000 light-years in diameter making these galaxies well beyond the stars and objects inside the neighborhood of our Milky Way.

The two brightest, fuzzy objects in the right center of the screen are the elliptical galaxies M86 and M84. The two galaxies in the upper left are known as “The Eyes.”

Speaking of eyes, in 1823 Wilhelm Olbers used his to look up at night and wondered why it is dark at all.
