Heart Nebula (IC 1805)

Heart Nebula (IC1805)

About the Heart Nebula

Popular Name Heart  Nebula
Catalogue Name IC 1805
Constellation Cassiopeia
Distance (Light Years) 7500
Additional Information Heart Nebula is diffuse emission nebula that , when viewed from Earth, happens to take the shape of a heart. It is quite large as seen from Earth, taking up more space than 2 Full Moons laid end-to-end.
Photographic Information
Exposure L-8x10min each for 2 panes, RGB-5x10min each for 2 panesTotal Integration Time: 7hrs and 40min
Equipment SBIG ST-8300m, Atlas EQ-G, Astro-Tech 111mm refractor,
Processing Deep Sky Stacker, Pixinsight
Imaging Location Lake San Antonio, CA

 

Notes: This was our first attempt at a mosaic with our CCD, and certain upgrades, such as a new Moonlite stepper focuser have helped us out tremendously. We are very pleased with the mosaic, especially as it necessitated that we learn many new processsing techniques in Pixinisght like Star Alignment and Gradient Merge Mosaic. There is still room for improvement though–maybe we will add narrowband data or another few panes to show all of the nebulosity in that region.

Triangulum Galaxy (M33)

M33

 

About the Triangulum Galaxy

Popular Name Triangulum Galaxy
Catalogue Name M33
Constellation Andromeda
Distance (Light Years) 2 million
Additional Information The Triangulum Galaxy is a close companion to the Milky Way, and is a part of the Local Group of galaxies. It is the farthest permanent object visible without a telescope, but can only be seen under the darkest of skies. Its many nebulous H-alpha regions even have NGC designations, the brightest four being NGC 588, NGC 592, NGC 595 and NGC 604.
Photographic Information
Exposures L-7x10min 4x5min, RGB-2x10min 2x5min

Total Integration Time: 3hrs

Equipment SBIG ST-8300m, Atlas EQ-G, Astro-Tech 111mm refractor,
Processing Deep Sky Stacker, Pixinsight
Imaging Location Lake San Antonio, CA

Notes: This was our first object taken with our new SBIG ST-8300 camera. Considering the meager integration time for LRGB, we are very impressed with the results. Although processing CCD images at first seems harder, the results are certainly worth the effort!

Witch Head Nebula (IC 2118)

WitchesHeadOrion

About the Witches Head Nebula
Popular Name Witch Head Nebula
Catalogue Name IC 2118
Constellation Orion
Distance (Light Years) 1000
Additional Information The Witch Head Nebula is a supernova remnant cloud in the constellation of Orion. It, by coincidence, has the unmistakable look of a witch’s head. The nebula glows blueish because it reflects light off of Rigel, a bright star nearby.
Photographic Information
Exposure 10×300 second

Total Integration Time: 50min

Equipment Canon 60d unmodified, Canon 300mm f4.0 lens, Astrotrac mount
Processing Deep Sky Stacker, Pixinsight
Imaging Location Death Valley, CA

Notes: This is our first attempt at using the Astrotrac mount with our 300mm lens. Although the lens itself had some optical aberrations (we did not step it down) the tracking of the mount, even without autoguiding was superb, allowing us to take 5 minute exposures without guiding. This is definitely an object we hope to attempt a mosaic with our AT 111mm on.
