It was over one year ago I started trumpeting the unnoticed treasures in our night skies, double stars. Along the way, I emphasised that you can observe them any time, anywhere, regardless of location, Moon light, or city light pollution.
Here's a short selection of doubles which I find interesting and impressive.
| star | also known as | alternate catalogue(s) |
|---|---|---|
| N Hya * | H 3 96 (Herschel), HD 100287 | HIP 56280, SAO 179968 |
| 54 Leo | Σ1487, HR 4259, HD 94601 | HIP 53417, SAO 81583 |
| τ (tau) Leo | 84 Leonis, STF I 19 | HIP 55945, SAO 118875 |
| α (alpha) UMa | β1077 (Burnham), Dubhe | HIP 54061, SAO 15384 |
| 35 Sex | Struve 1466 | HIP 52452, SAO 118449 |
* There's something odd about N Hydrae. Online resources say this is 17 Crateris. But this suggestion I followed from Sky & Telescope does indeed show a neat pair at 11h 32m 16.40s, -29° 15' 39.7".
Consider adding these to your observing list. Doubles are fun! I look forward to hearing how you make out. Holler if you have any questions.
