SH2-311 in Hubble Palette

SH2-311v4HST image

Another narrowband image, this is SH2-311. It’s located in the constellation of Puppis, and about 20,000 light years away. It’s very low in our skies, below 30 degrees, and I usually don’t do anything lower than 40 degrees. It’s an attractive object with the Hubble Palette though, and these narrowband filters let me get this image with a bright moon. Taken over 4 nights, ending April 8, 2015, and seeing was below average, which added to the challenge of this object being close to the horizon. It’s a total of 7.5 hours of exposure, with mixed 10 and 20 minute sub-exposures. This is taken with my new STF8300m camera, which has a full set of narrowband filters.  Click on the image for a larger view.
