Theta2 Orion

Star: Theta2 Orion 
Date & Time: November 18, 2000, 00:00 MET  
Seeing: --- <1-10 Seeing Scale (10 best)> 
Location of site: Annen, The Netherlands 
(53 N, 6 E) 
Site classification: Village-backyard 
Sky darkness: 4 <Limiting magnitude>  
Conditions: Some clouds 
Temperature: 5ºC 
Binocular: Swift Supreme 10x50 (on tripod) 
 		 A rather wide pair of bright young stars. Beautiful because they are embedded in the glow of M42. They sit next to the famous Trapezium (Theta-1). 

Their position in one of the most beautiful and interesting starfield in our sky, Orion's sword, makes this a real showstopper. 
In the same FOV we see, beside the nebulous glow of M42, several other doubles : 
Theta-1, The Trapezium, which cannot be separated with 10x. 
42+45 Ori, a very wide pair to the north of M42 and the most attractive one : 
Stuve 747, a nice little double near Iota Ori (south of M42).

 		 Still near the heart of the Orion nebula and lying about 2' SE of the trapezium is a row mag. 5.2, 6.5 at 52" and the fainter 8.4 at 1'17". Again this group is enhanced by its closeness to Theta 1+2 and the glowing white stars stand out like beacons in the 
sea of glowing star dust. 
 
Comments: Stopping down the 25X100 to 25X50 still reveals all three stars. No photograph is as sensitive as the human eye to capture the nuances of light and dark and subtle hints of colour generated in what for me is the most impressive field in the 
night sky.
