The Garden Astronomer website is an online diary of personal astronomical observations from suburban light polluted skies. It contains popular objects viewable without a large investment in equipments as most the targets can be seen using small to moderate-sized telescopes. This page also includes reflections from Wayne McGraw on his return to observing during the COVID-19 pandemic.

Exploring Black Hole Cygnus X-1 and Its Companion Star
In my article on Cygnus X-1, I cover the black hole and its massive companion star, HDE 226868, along with how they interact through stellar winds. I’ve also included my own photos and clear illustrations to show exactly where the system is located in Cygnus. It’s a mix of science, observation, and practical stargazing guidance.
NGC 6871: A Simple Sparkling Cluster in Cygnus
Explore the open cluster NGC 6871 in Cygnus with my observing notes, sketch, and Seestar photo. I also highlight the fascinating Wolf–Rayet star WR 133.
Marsic (Kappa Herculis): A Garnet and Topaz Double Star
Learn about Marsic (Kappa Herculis) and see how it looks through an 8-inch SCT scope when viewed from a suburban location. Marsic is an optical double star in the constellation Hercules and best viewed in summer.
T Coronae Borealis (The Blaze Star): Observing Before Explosion in 2024
The binary star T Coronae Borealis is expected to go nova in 2024. To prepare for this stellar event, I share why it’s special and share how the star appears before it explodes using an astrophoto and a sketch taken from my backyard in Seattle in June 2024. The binary is also registered as T CrB, SAO 84129, HR 5958, HD 143454, HIP 78322.
The Iris Nebula: A Flower Blooming in the Dark
Explore the stunning Iris Nebula (NGC 7023 or Caldwell 4), a breathtaking reflection nebula in Cepheus. Discover how the central star illuminates its dust and gas, creating a glowing blue celestial flower. See my sketch and Seestar S50 image to visualize what you can expect to see. Learn about its history, distance (1,300 light-years), and why astrophotographers cherish this beautiful autumn target.
Struve 730: Double Star in Taurus
Get a close look at STF 730, a nearly equal double star perfect for winter observing. This article includes my own telescope sketch and notes on the subtle color contrast between the faintly blue primary and white secondary. Ideal for double star enthusiasts building their observing lists.
Struve 3116: A Tight Double Star in Canis Major
Learn about the tight double star Struve 3116—its close 3.9″ separation, blue-white components, and observing tips. This article also includes my personal sketch so you can see how the pair appears through the eyepiece. Known as SAO 151401, HD 44458.
