Description

The picture was taken from the center of Rome, in an area of the sky where Antares was the only visible star due to strong light pollution. I could not believe to my eyes when I understood that CCD could take a good picture!

M95 a Barred Spiral Galaxy located in the constellation Leo (next to Mars now). It has a peculiar core of strings of clusters and currently several days ago a Super Nova has developed marked, Presently shines at magnitude 13 and is exspected to brighten more. Light reflections spikes due to Mars being close 1/2 deg. effected the image the inset is before without the SN. Same Equipment on both images and author.

Date

Four nights between August 26 and September 1, 2011.

Equipment

Telescope: PlaneWave Instruments CDK17, with a focal reducer at f/4.5. Mount: Paramount ME. Camera: SBIG STL-4020M. Image capture: TheSkyX, MaxIm DL, and FocusMax. Exposures: 300 minutes luminance (unbinned), 100 minutes in each of red, green and blue (2x2 binning). Ten-minute subframes in all channels. Image scale: 27' on a side, 0.78" unbinned pixel size. Image Processing: PixInsight with CCDInspector.

Description

This is a new image: although the frames were shot last summer, I could only recently complete the image processing. I was drawn to the Cave by its wide expanse of dark nebulae, the deep colors of its emission and reflection nebulae, and the vivid assortment of stars splashed across the field. I set up the shot so that a small grouping of colorful stars would spill into the corner of the frame, as if they were jewels falling out of the entrance to the cave. Over 16 hours were shot, with only the best 10 hours kept for processing.

Description

Here is a picture of spiral galaxy M94. This is a spiral galaxy about 16 million light years away in the constellation of Canes Venatici. It is notable for having two ring structures. The inner ring is a site of strong star formation known as the starburst ring. The outer ring is a complex structure of spiral arms.
