The Big and Little Dipper

 This time of year the two asterisms known as the Big Dipper and Little Dipper stand high in the northern sky.  These two star patterns are part of the formal constellations Ursa Major and Ursa Minor.

Little Dipper.  Hoya Softon filter.


Sony A7iii + Laowa 15mm f/2 + Sparkle-6x filter.  ISO 1600, 30 s.

Little Dipper.  Hoya Sparkle-6x filter.

I like both of these two filters.  The Softon filter gives the stars a more natural appearance.  The Sparkle-6 filter results in a more artistic flair.

For those not familiar with these star patterns, here is a finder chart:

The sky brightness when these images were obtained was sqml=21.69 mpsas.  See the previous post for an explanation of this number.
