ST-4000XCM, 1200s total exposure 6/14/12 Monte Bello Open Space Preserve, CA
Our first image of an emission nebula with the ST-4K!
Starshoot DSCI, 110 exposures, 10s each 9/27/08 Lake San Antonio, CA
The focus here is not ideal - also it was very low in the sky. More than one image scaling is needed to show both the hourglass feature in the brightest part of the nebula, and the fainter structure that fills the rest of the image.
