I wanted to go after the Wizard Nebula (NGC 7380) again. My first attempt was four months ago. Now equipped with a new telescope and better post-processing techniques, I thought it would be worth it to try again. I much prefer this result over my old one. I used all three narrowband filters. I also added OIII to the California Nebula. Here is more info:
