Beyond the Weird and Wonderful World of 8 Andromedae: Σ 2987, OΣΣ 244, and OΣ...
Our last trip concentrated on 8 Andromedae/BU 717 and the area immediately southeast of it, so this time we’ll wander a bit farther afield. But we’ll have to take care that our first leap into the...

The Weird and Wonderful World of 8 Andromedae: BU 717, ES 2725, and ARY 3

Now that we have the STT pairs in Lacerta wrapped up (here and here), we’ll finish this series by looking at four rather challenging STT objects in Cepheus. For the most part, these are going to...

STT Objects in Lacerta, Part 1: OΣ 475, OΣ 477, and OΣ 479
It’s rather ironic that I find myself back in Lacerta once again, which is the scene of the last post I wrote here several months ago. But this is an intriguing little constellation, dim though it is,...

Difficult Double Stars of the STT Variety
Back in the golden era of the late nineteenth and early twentieth centuries, when astronomy began to grow rapidly in the United States and Europe, communication with other astronomers was a slow...

It had been a long while since I last took a stroll through Lacerta, so I had to grab my well-worn copy of Sky and Telescope’s Pocket Sky Atlas and relocate the constellation’s dim outline between...

Sleuthing in Sight of Sadalmelik: OΣ 460, Σ 2862, and Σ 2855
If it seems like we’ve been here before, it’s because we have – just a month shy of a year ago, when we looked at “The Alpha-Beta-Gamma of Aquarius,” and discussed Homer-era Greek grammarians, urns of...

Another Way to Polar Align
If you’ve been reading this blog for a while, you probably realize I thread my way through the night sky by star hopping. There was a time when, like many other people, I used a Go-To mount and let...

A Closer Look at Eta (η) Lyrae, Including SHJ 289, HLM 19, and SEI 584
Relegated to a blue-white existence well beyond the Lyrae-ian framework, Eta (η) Lyrae beams its fourth magnitude photons at us from about seven degrees due east of Vega, the jewel in the...

From 68 Herculis (OΣ 328) to 72 Herculis and Beyond to H N 5
If you look at a star atlas (for example, chart number 52 of Sky & Telescope’s Pocket Sky Atlas), just a few degrees east of the Herculean keystone you’ll find a pair of fifth magnitude stars...

Beta (β) and Zeta (ζ) Lyrae: A Closer Look — and a TAR 3 Tale

A Stellar Stroll through Southern Lynx, Part 2: 38 Lyn, Σ 1338, and 10 UMa
When we last left Lynx, we were lingering over the mysterious tug-of-war taking place between the two components of Σ 1333. Ahead of us, just a degree and a half north of that pair, a consecutively...

A Stellar Stroll through Southern Lynx, Part 1: Alpha Lyn, HJ 2491, and Σ 1333
It’s long, it’s spread out, and it’s dim – all of which I suspect are reasons you never hear or read much about Lynx, as well as reasons most people don’t visit it. At any rate, it’s never been all...

Crowded Starlight in Leo: OΣ 215, OΣ 216, Σ 1417
For as large as Leo is, it’s a little light on double stars. That’s not surprising since it lies north of the plane of the Milky Way, but it also explains why it’s a rich hunting ground for galaxies....
