Description

Data captured on 10/06/2021, 10/07/2021, 10/09/2021, and 10/17/2021. I had to throw out a large chunk of data as I was battling dew and didn't have a dew heater at this point, but I'm pretty happy with how it turned out anyway.

This is a busy and interesting region of the sky with all sorts of different things going on. 

The Lobster Claw Nebula (Sh2-157) is a bright emission nebula at an estimated distance between 8,000 and 17,000 light years from Earth. It's a large region spanning about a degree in our sky.

The Bubble Nebula (NGC 7635) is an H II emission nebula and is located between 7,000 and 11,000 light years from Earth. The bubble is 7 light years across - about 1.5x the distance to our nearest star and is created by the stellar wind of its hot central O-type star that is 45 times more massive than our sun.

The Northern Lagoon Nebula ❨NGC 7538❩ is an emission and reflection nebula located about 9,100 light years from Earth. Within in lies the largest discovered protostar (a young star that is still gathering mass from its surrounding molecular cloud) at over 300 times the size of our solar system. It is a region of active star formation.

Sh2-159 is an H II region located approximately 10,000 light years from Earth that contains a compact source of radio waves surrounding its class O9 V star that causes most of the nebula's ionization.

NGC 7510 is an open star cluster (a cluster of a few thousand stars formed from the same giant molecular cloud) located 11,400 light years away. The stars in this region are very young, at only about 10 million years old.
