Description

It sorta looks like California, tipped over with North to the left... This is made with the Epsilon 180ED scope (180mm f/2.8) and STL-11000xm camera from home in Sacramento. This version has 100 minutes of H-alpha and 60 minutes of Sulphur II. The Ha was mapped to G and B, and the SII to Red. It was processed in CCDStack and combined and finished in Photoshop. The Ha was grabbed in early February when it was well-up in the sky, while the SII was had in mid-March, with the nebula only about 30 degrees above the western horizon when the last SII image was made.
