Image Details:

The North America (NGC7000) and Penguin Nebulae (IC5070) high in the indian-summer sky from Joppa, Texas, taken 2021-09-05 06:30 UT. These are both parts of the same nebula. The apparent division is caused by a dark nebula (L935). This dark nebula also obscures the ultra hot bright UV star that energizes the emission nebulae.

The summer of 2021 has had the 3rd highest number of rainy days in the recorded history of central Texas. Last Saturday was not one! I've shot both of these individually and am now pleased to have them in one image.
