viewed The 37 (Blue Mountains)

Tried to view the 37 Cluster. Up in the arm of Orion.

3:04 AM. I found it was tiny! Tele Vue 'scope made it look tiny. In the C14, I spotted a double star in it.

SkyTools shows HD 41943 aka Σ848 as a multi-star system that is the whole 37 Cluster! Nutty. The star at the top of the 3, closest to the 7, is the primary star, A. Letters up to Q and R. Impressive! The AB pair is about 2 or 3 arc-seconds apart. [ed: Haas refers to this, as Struve 848, but only notes the AB pair.]

Yawned. Tired. Long day...

3:12. Rob was packing up. Looked like he was leaving; I thought he was staying.

Bill started packing up. Showed me Messier 1 (M1) in his SCT. And the Orion Nebula (Messier 42 or M42).

I tried to find a planetary nebula. NGC 2022. Without success.

Bill and I discussed a night-cap. I closed the roof and parked the 'scope. Done.
