(Click on image for full size inverted version)


Description: This fascinating galactic cluster is thought to be approximately 1-1.5 billion light years distant.  Many small, faint galaxies are seen in this image.  beyond identifiable galaxies down to magnitude 18.7 there are many visible that are much fainter.  North is to the right.
Exposure Data: 5/23-24/2006.  48 x 10 min binned 1x1.   -25C, 0.58 arc-sec./pixel.
Processing: Acquired via CCDAutoPilot 3 and CCDSoft, reduced, aligned and combined in CCDStack, curves, levels and other processing in Photoshop.
Optical System: 14.5 Ritchey-Chretien @ F/9 w/FFC, IMG6303E/CFW-7 CCD camera, AstroDon filters, Paramount ME, dithered 3 pixels, off-axis guided.
Comments: This is probably the most distant object I have imaged.  The background is set high to preserve the faint objects.  Many objects were identified by image linking into TheSky6.  Average seeing was under 2.0 arc-sec.  Click on the inverted image, showing more of the fainter galaxies.
