The Cave Nebula… through the smoke 💨🔥💀
We have so many started projects from before the California wildfires, but that are impossible to finish due to the California wildfires... In this image of the Cave Nebula, the OIII and SII were shot through thin layers of smoke... Luckily, We already had a bunch of HA from before all these crazy fires started. I’ll probably wait for the skies to clear up before finishing the other project, and will reshoot this one if possible.
