Last nebula of the season

Here I have the California Nebula in HA-RGB taken over several nights in December.

A Hubble palette image created using data from 3 narrowband filters, Sulfur assigned to red, Hydrogen alpha to green, and Oxygen to blue, AKA a false color image

….1470 light-years from Earth!

Messier 97, a planetary nebula in the constellation Ursa Major.

The Pleiades also known as the Seven Sisters and Messier 45

M78 belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. 

15 hours in total, 6 hours of HA, 9 hours of OIII

3 hours and forty minutes on this so far.
