This is my first time re-visiting the Rosette since my first "good" astrophoto, which was on the Rosette, back in February 2017. I've been doing H-alpha all month long in my backyard, and I just switched back over to my color camera, so I went ahead and processed the H-alpha data on the Rosette! Color data will be added next (when the California wildfire smoke clears!)
