#BigDipper must be the most famous #constellation ️ I choose to represent it entirely. It's made of #LedLights, a secondhand wooden #frame and pressed elder flowers and solanum

Evening constellation shot looking north, bracketed by trees.

Two asterisms are visible: the Big Dipper and the Little Dipper...which are part of the constellations Ursa Major and Ursa Minor.

https://en.wikipedia.org/wiki/Asterism_(astronomy)

I only wanted to capture a small number of stars so that the asterism patterns would not be lost in the clutter. Shooting in twilight makes fainter stars less detectable.

To make the stars more visible, especially on smaller screens (cell phones), I did the following image processing:

- blur (Gaussian)
- dilate filter
- blur
- dilate
- blur

The first blur operation was to smooth out the high spatial frequency noise.

Dilate filter expands the size of stars, but also makes them more square instead of round...so...

...you need another blur operation after every dilate operation.

Enjoy!

Another wand from last night's shift at the woodburner! This one has renditions of the Big and Little Dipper (not bad if I do say so myself). The runes are meant to say "True North," which is what the Dippers can help to find.

Polaris, the current North Star, can be found in the Little Dipper's handle.

How about we do a big dip into the Montana northern lights? Donna Fiveland (Red Lodge), Carla Meyer (Forsyth), and Gina Woody (Wilsall) sent beautiful photos of the northern lights AND the Big Dipper! Thank you, everyone!
