The recent weather in California has been quite a stark contract to previous months. It's been smokeless and clear. I've been able to capture some serious nebula time, especially around the Cassiopeia constellation which is full of nebula and activity. Neighbors with my previous image, the Fishhead Nebula (IC 1795) is a rich region of gas and dust which has a lot of Ha which is common for nebula... but it's also bursting with OIII (blue) in the center region giving it some very nice contrast.
Image specifications below.
Chroma 3nm HA - 222x300s - 18.5 hours
Chroma 3nm OIII - 38x300s - 3.1 hours
Chroma 3nm SII - 38x300s - 3.1 hours
