DEEP SKY DUO IN CEPHEUS:  NGC-6939 an open cluster (top left) and NGC-6946 a face-on Type Sc Spiral Galaxy (bottom right). This is a pleasing group when
viewed in moderate sized telescopes, and the image represents an astounding depth of field: The open cluster is in our Milky Way galaxy at a distance of about
5800 light years from Earth, whereas the galaxy NGC-6946 lies at a distance of
18 million light years!! Also, please notice, between the two bright stars just below the
cluster the small faint 15th mag. edge-on galaxy UGC-11583.  
Note:  This image captured on the evening of August 12th, 2015. It is a 1 hour 40 minute exposure
(ten 10-minute sub-exposures) through the C-11 @ f/2 using HyperStar and the Starlight Express SXVR-H694C color imaging camera. Guided and captured using
Maxim DL 5 Pro. Stacked and color converted in Maxim.  Post-processed using PhotoShop CS2, levels, curves, Gradient X-terminator and StarShrink.
M-74 (NGC-628): M-74 is a large face-on "Grand Design"(i.e; having two well-defined spiral arms) galaxy in the constellation of Pisces, about 1.5
degrees ENE of Eta Piscium. It was discovered in 1780 by Pierre Mechain and added to Messiers catalog the same year. Visually, it is about 9 arc
minutes in diameter, which corresponds to an actual diameter of 95,000 light years at its estimated distance of 32 million light years from Earth.
NOTE: This image captured on November 8, 2015. It is an integration of twelve 10 minute exposures for a total exposure time of 2 hours through
the C-11 at f/2 using HyperStar and the SXVR-H694C CCD imager. Guided, captured and combined using Maxim DL Pro v. 5.2. Post processed
using Photoshop CS2.  This image clearly shows the many H-II star forming regions within the two spiral arms of the galaxy.
NGC-1365: A large, face-on barred spiral galaxy located in the constellation of Fornax, the furnace, close to its border with the constellation of
Eridanus. NGC-1365 lies approximately 56 million light years from Earth. Visually it is approximately 11 arc minutes by 6 arc minutes in size,
which at this distance corresponds to an actual diameter of over 200,000 light years, making it almost twice the size of our own Milky Way galaxy. It is
the largest and brightest barred spiral galaxy in the northern sky. Also shown in this image are three other galaxies. Directly to the east, (right) is the oval
spiral galaxy NGC-1386, which lies just across the border in Eridanus. Just south of it is the smaller spiral galaxy, NGC-1369. Finally, just above
NGC-1365 (north) is the small 16th magnitude galaxy PGC-13131.
NOTE: This image was captured on the evening of January 13th, 2016, and is a 1-hour exposure through the Celestron 11" SCT at f/2, using the
HyperStar imaging system and the SXVR-H694C CCD imager. This image was guided, captured, and combined using Maxim DL Pro, v 5.2.
Post-processed using PhotoShop CS2, levels, curves, filters, and Gradient XTerminator.
M-42 (NGC-1976), The Great Nebula in Orion:  This is a wide field image, 1.2 X 1 degree, showing the Orion Nebula, M-42 and the smaller nebula M-43,
just to its left (east), as well as the "Running Man" reflection nebula (upper left center). This image captured at Land of Oz Observatory on November 8, 2015
using the C-11 at f/2. Total exposure time 76 minutes. This image is a composite of sub-exposures of varying length, with shorter exposures to capture the
inner details of the area around the "Trapezium" of stars at the heart of the nebula, and progressively longer exposures to capture the faint outer extensions
of M-42/43, as well as the fainter reflection nebula.  A total of 160 sub-exposures were integrated to create the above image.
Guided, captured, combined and processed using Maxim DL 5 Pro. Post processed in PhotoShop CS2, levels, curves, color balance & saturation and
differential stretching, Gradient X-Terminator and Croman's StarShrink.
SUPERNOVA 2016-cok IN GALAXY M-66: Discovered May 28, 2016 by the All-Sky Automated Search for Supernovae (ASAS-SN) of Ohio
State University, located on Mt. Haleakela in Hawai'ii. This exploding star erupted in the spiral galaxy M-66 in Leo, which lies over 35 million light years
from earth.  The explosion was caused by the collapse of a massive star some 8 to 50 times larger than our sun. The collapse and subsequent shock
wave caused a titanic outburst known as a type II supernova. When first discovered, it shone at approximately 16.7 magnitude, but had brightened
somewhat by the time this image was captured on the evening of June 4, using my Celestron 11 at f/2 using the HyperStar imaging system with a
StarlightExpress SXVR-H694C one-shot color CCD imager. This is an integration of 7 300 sec. exposures. Guided, captured combined and processed
using Maxim DL 5 Pro. Post-processed using PhotoShop CS2, levels, curves, color balance & saturation, Gradient X-Terminator and StarShrink.
The Fornax Galaxy Cluster: This is a group of over 15 galaxies located in the constellation of Fornax (The Furnace) near its
border with Eridanus. The cluster is anchored by a pair of massive elliptical galaxies, NGC-1399 and NGC-1404, and contains
both other ellipticals and spiral galaxies, such as NGC-1380, at the northern edge of the cluster. This group of galaxies lies at a
distance of about 62 million light years from Earth.
NOTE: This image is 1 hour of data (10 six-minute subs) through the Celestron 11" SCT at f/2, using HyperStar and the Starlight
Xpress SXVR- H694C color imager. Guided, captured and calibrated using Maxim DL5 Pro. Post-processed in PhotoShop CS2,
using levels, curves, color balance, Gradient X-Terminator and StarShrink.
SUPERNOVA 2017eaw IN SPIRAL GALAXY NGC-6946: This supernova was discovered on May 14, 2017 by
Patrick Wiggins. It is a type IIP (Plateau) supernova, caused by the collapse and subsequent explosion of a massive
star. This is the 10th supernovae to erupt in this galaxy in the last 100 years! This image was captured on the
morning of May 29th, at which time it was shining at 12.8 magnitude. This is one hour of data (10 six-minute
exposures) through the Celestron 11-inch SCT at f/2 using HyperStar and the SXVR H694C CCD color imager.
Guided, captured and combined using Maxim DL5. Post processed using PhotoShop CS2.
SUPERNOVA 2017ein in Galaxy NGC-3938: This supernova was discovered on May 25th, 2017, at which time it
was at 17th magnitude. NGC-3938 is a large face-on type Sc galaxy in Ursa Major and lies approximately 40 million
light years from Earth. Spectroscopy indicates that this is a type II supernova, caused by the collapse of a super
giant star. This image was captured on the evening of June 19th, 2017, when the supernova was at 15th magnitude.
48 minutes of data (8 six-minute subs) through the C-11 at f/2 using HyperStar and the SXVR-H694C 1-shot color
imager. Guided, captured & combined using Maxim DL5. Post processed using PhotoShop CS2, levels, curves,
Gradient XTerminator and StarShrink.
THE NORTH AMERICAN NEBULA (NGC-7000): This is the "FIRST LIGHT" image from the new ZWO ASI-071-MC CMOS-based imaging
camera.  The camera is a 16 mega-pixel 1-shot color camera. Using the HyperStar system at f/2 on the C-11, it has a resolution of 1.76 arc
seconds per pixel and a field of 145 X 95 arc minutes (almost 2.5 X 1.5 degrees). This allows for the imaging of larger deep sky objects such as
the nebula above, as well as large galaxies like M-31 and M-33.
NOTE: The above image was captured on the evening of October 17, 2017 and is an integration of twelve 360 second sub-exposures for a total
integration time of 72 minutes. The image was guided, captured and combined using Maxim DL 5 Pro. Post-processing was done in PhotoShop
CS2, using levels, curves, colorbalance & saturation, Gradient XTerminator and StarShrink.  This very first image shows that the new camera has
definite possibilities!
M-31 (THE ANDROMEDA GALAXY) AND COMPANIONS: This was the SECOND image captured with the new ZWO-ASI 071- MC
camera on the evening of October 17, 2017.  Nicely framed in the 2.5 X 1.5 degree frame are M-31, M-32  and NGC-205. The 1.76
arc second/pixel resolution of this camera captured nice detail in M-31, including lots of dust lane detail and many scattered star
clouds in the spiral arms, including the bright OB supergiant association NGC-206 (visible in the outer spiral arm at the upper right).
NOTE: This is an integration of ten 360-second exposures through the C-11 at f/2.
Guided, captured and combined using Maxim DL5 Pro. Post-processed using PhotoShop CS2, levels, curves, color balance and
saturation, Gradient XTerminator and StarShrink.

SUPERNOVA IN URSA MAJOR GALAXY
THE "DOUBLE CLUSTER" IN PERSEUS: The common name for the pair of open star clusters NGC-884 (left) and NGC-869
(right) which lie in the constellation of Perseus. This pair of clusters is visible to the naked eye as a faint misty patch east and
slightly south of the familiar "W" shape of the constellation Cassiopiea. They lie at a distance of approximately 7500 light
years from Earth. NGC-884 is distinguishable from its neighbor due to its more open structure and the presence of a number
of bright red supergiant stars.
NOTE: This is the THIRD image obtained with the new ZWO ASI071 MC wide-field color imager. It is an integration of six 360
second exposures for a total integration time of 36 minutes. Guided, captured and combined using Maxim DL5. Post
processed using PhotoShop CS2. This image was captured on the evening of 12/18/2017.
NGC-147 (RIGHT) AND NGC-185 (LEFT): A pair of dwarf elliptical galaxies located in the constellation of Cassiopiea,
about 7 degrees north of M-31, the Great Andromeda Galaxy. This pair of small faint galaxies are gravitationally bound
to the larger M-31, and lie at a similar distance.
NOTE: This is the FOURTH image obtained with the new ZWO ASI071 MC wide-field color imager. It is an integration of
three 360 second exposures for a total integration time of 18 minutes. Guided, captured and combined using Maxim DL5.
Post processed using PhotoShop CS2. This image was captured on the evening of 12/18/2017.
THE PLEIADES (M-45): An open star cluster and nebulosity located in the shoulder of Taurus the Bull. This large bright
star cluster lies only 400 light years from Earth. It is a relatively young cluster and contains young, hot, super luminous B-type
stars that have formed in just the last 100 million years. The dust which forms the nebulosity that surrounds the brightest
members was once thought to be left over from their formation, but is now known to be an unrelated dust cloud in the
interstellar medium through which these stars are currently passing.
NOTE: This is the FIFTH image obtained using the new ZWO ASI071 MC wide-field color imager.  It is an integration of ten
360 second exposures for a total exposure time of 1 hour. Guided, captured and combined using Maxim DL5.
