OBSERVER'S CORNER

By Professor Hal Jandorf

Anza-Borrego desert is a stargazer’s paradise.

It’s a quiet, peaceful climate with crystal dark-blue daytime skies above and a spectacular night sky. The temperature at night allows comfortable shirtsleeve activity for observing and imaging.

In late summer/early autumn, the Milky Way spans from horizon to horizon, bright and detailed with galactic clusters and nebulae.

The photo was taken on September 27, 2019 with a Sony A7 camera, 28mm, f/4.5, ISO 1600 and 1 minute exposure. I used an iOptron Star Tracker to avoid star trails.

The image was taken from the Borrego Valley Inn patio outside of the room. Here, there are no obtrusive lights, just a dark sky. I recommend this Inn for reconnecting our inner selves with the magnificent Universe!

Late summer is a perfect time to observe the “Summer Triangle”, the three bright stars of Vega, Deneb and Altair that are at the zenith at 9 pm in mid-September.

The triangle which points South contains many celestial objects: two bright planetary nebulae, a supernova, an emission nebula, and asterism and a famous double star!

All can be seen with  4 inch diameter telescope in dark skies.

  1. M-57 Ring Nebula: A planetary nebula shows stellar death, a sphere of hydrogen and helium escaping from a white dwarf. 2000 Light Years distant, RA 18h54m Dec +33

  2. M-27 Dumbbell Nebula: Another planetary nebula. 1400 LY, RA20h00m     Dec +22.7

  3. Veil Nebula: (NGC6992)A supernova Remnant, best seen in very dark skies and a OIII nebula filter. 1400 LY, RA 20h56m dec +32

  4. North America Nebula: (NGC7000)Birth of stars, use a nebula filter and extremely low magnification. 1500 LY, RA 20h59m Dec +44

  5. The Coathanger asterism (Collinder 399) RA 19h25m Dec+20

  6. Albireo, the UCLA double star. What colors do you see? 386 LY, RA 19h31m Dec +28
