This image uses data provided by Dr. Philip Massey as distributed by the NOAO Science Archive. NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under a cooperative agreement with the National Science Foundation. Observers: K. Olsen, C. Smith

 

Data for this image was obtained with the Blanco 4-m Telescope at the Cerro Tololo Inter-American Observatory in Chile and is publicly available from the NOAO Science Archive.

 

The 4-m telescope is able to resolve individual stars. Please zoom in for an up close look!

 

This image is a blend of narrow band data gathered with Ha, SII and OIII filters. Each of the original frames was a 2x4 mosaic with a total of 8675x8775 pixels. The view presented here is a crop of the full frame that has been reduced to half the original resolution. Still the largest image provided here is 3200x2400 pixels and it shows lots of detail.
