B35: A Deep, Dark Nebulae
Test your observing skill at low magnification

Appearing as a dark hole in the winter's sky, B35 is a dark nebulae with relatively high opacity.

How to find B35:
1. Look for the bright star Betelgeuse in the northeast corner of Orion.
2. 6º northwest of Betelgeuse is 3.4 magnitude Lambda Orionis, primary star of the "Orion's Head Nebula," also known as Collinder 69.
3. Midway between Betelgeuse and Lambda hides B 35.

How to view B35:
• Use a low magnification.
• Transparent, dark skies are a must.
• Must be able to distinguish small differences in contrast.
• View when no moon is present.
• Best seen near culmination.
