Globular Clusters M-53 (lower left) and NGC-5053 (upper right) in Coma Berenices: These two
globulars offer a distinct contrast in both brightness and structure. M-53 is a relatively dense cluster
with a concentrated middle, while NGC-5053 has a very loose structure and no central condensation at
all. M-53 is a fairly distant cluster, lying almost 60,000 lightyears from Earth. Although NGC-5053 is
slightly nearer, at 53,000 light years, it appears much fainter, due to the fact that it has a very loose,
open structure with no central concentration. Also, it is composed of fainter stars. M-53, on the other
hand, is quite dense in structure and has slightly brighter stars. The two clusters are separated by an
angular distance in the sky of about 1 degree. NOTE: This image captured on the evening of June 11,
2013, and is an integration of fifteen 4minute exposures through the C-11 at f/2 using HyperStar and
the SXVR-H694C CCD imager, binned 2X2 for greater sensitivity (resulting in a monochrome image).
Captured and combinedusing Maxim DL 5 Pro. Post processed using Photoshop levels & curves,
Gradient X-terminator, and Carboni's Astro-tools.
Supernova in Galaxy M-74: This type II supernova was discovered on July 25th, 2013 by astronomers
at Lick Observatory. This image was captured on the morning of August 11th, 2013, and is a quick
exposure of only 1/2 hour through the 11-inch Celestron at f/2 using the Starlight Express SXVR-H694C
imager. Captured and combined using Maxim DL 5 Pro Post-processed in Photoshop levels & curves,
Gradient X-terminator and Astro-Tools. On the right is a Digital Sky Survey image, pre-supernova, for
NGC-7814: A precisely edge-on SA type galaxy in Pegasus, located about 2 degrees NW of 2nd magnitude
Algeneb (Gamma Pegasi). Visually, it is about 6 X 2 minutes of arc in size, and lies approximately 76 million
light years from Earth. It is bisected by a knife-edge thin equatorial dust lane which shows plainly in this
image, which is a 1-1/2 hour exposure (fifteen 6 minute subs) through the C-11 at f/2 using HyperStar and
the SXVR-H694C 1-shot color CCD imager. Captured and combined using Maxim DL 5.2. Post-processed
using Photoshop CS, levels, curves, and Gradient X-terminator.
M-45 (The Pleiades Cluster): Located in the constellation of Taurus, The Bull, the Pleiades
are one of the nearest open clusters to Earth, lying only about 400 light years distant. It is a
very young cluster, being only about 100 million years old (compare to our sun, which is 5
billion years old!). This cluster is dominated by hot, extremely luminous blue-white stars. The
cluster is enveloped in a vast cloud of interstellar dust which is not related to the formation of
the cluster, but which the main stars are currently passing through. The most famous part of
this dust cloud is the reflection nebula surrounding the star Merope, nearest the right center
of the image.
NOTE: This image was captured on the morning of November 8th, 2013, and is an integration
of eight 6-minute sub-exposures through the 11-inch Celestron using the HyperStar imaging
system and the Starlight Express SXVR-H694C 1-shot color CCD camera. The images were
captured and combined using Maxim DL 5 Pro. Post-processed in PhotoShop CS, using
levels, curves, color saturation and Gradient X-Terminator.
