Great Lakes Star Gaze in Gladwin Michigan: September 2023
I've had the honor of meeting some fantastic guys from MI thanks to Doug Bock who hosted online imaging sessions that I joined up with in 2019. Doug, Awni, Tony, and Steven invited me into their FB Messenger group. I've been able to share a few days with them at GLSG in September the last three years. They really are fantastic guys. The GLSG offers Bortle 3 skies, which is very dark.

The Dark Shark Nebula (LDN 1235)
Last year I blew the effort to get this amazing Shark, I ended up with the wrong rotation and cut off his head. 😬
This year, I'm delighted with the effort.

I just love this asterism of stars! This was my first view through a telescope back in my early 20s. I have been hooked on astronomy ever since.
Commonly called the Pleiades or Seven Sisters, M45 is known as an open star cluster. It contains over a thousand stars that are loosely bound by gravity, but it is visually dominated by a handful of its brightest members. Reference NASA
The light from the blue star reflects off the surface of 'pitch-black clouds of cold gas laced with dust.' This produces a reflection nebula.
Luminance
Some of my favorite objects to image are dark or dusty nebulae. Whenever I come to GLSG, I always avail myself of the dark sky to shoot these objects I can't shoot from home very well.
LDN (Lynds’ Dark Nebulae) 673 is a highly fractured and very dense dark cloud complex of about 7 light-years across, located in the center of the Aquila Rift, some 300 – 600 light-years from Earth in the northern constellation of Aquila (the Eagle).
