IC2948 by Matt Dieterich
Submitted August 3, 2020 by Matt Dieterich
Here is a view of an emission nebula in the constellation Centaurus known as the Running Chicken Nebula. The bright glowing red is hydrogen gas that is emitting red wavelengths of light after absorbing energy from nearby starlight. I used a CDK24 telescope and L-600 mount to capture 8 hours of images through LRGB filters from Observatorio El Sauce. I processed the images with PixInsight and Photoshop.
Centaurus A Galaxy by Matt Dieterich
Submitted August 3, 2020 by Matt Dieterich
I imaged the Centaurus A Galaxy from the pristine dark skies of Observatorio El Sauce in Chile. The galaxy is an estimated 10 to 16 million light years away. Amazing to think that the galaxy is also 60,000 light years across! So that means the light takes 60,000 years to travel from one end of the galaxy to the other end! Considering 1 light year is 5.8 trillion miles I can’t even fathom that scale! Imaged in collaboration with Nick Dunckel and his CDK24 and L-600 mount. I used 10 x 5 minute exposures through LRGB filters
NGC3579
Submitted August 3, 2020 by Matt Dieterich
Pictured here is over 26-hours of exposure on a beautiful nebula visible in the Southern Hemisphere known as NGC3579. I used a CDK24 and L-600 mount to capture images with the FLI Proline 16803 CCD camera from the dark night skies of Observatorio El Sauce. The camera collected wavelengths of hydrogen gas (greenish color), sulfur (brownish red color), and oxygen (bluish color). When combined and mapped to RGB channels, the resulting Hubble Pallette colors are shown. Needless to say I was blown away while processing this nebula!

47 Tucanae by Damian Peach
Submitted July 21, 2015 by Planewave Instruments
CDK20″ @ F4.5. FLI camera. RGB: 45mins.
Possibly the finest globular cluster in the entire sky. Visible to the naked eye alongside the Small Magellanic Cloud, the massive ball of stars is 16,700 light years away from our solar system and is 120 light years in diameter. Unlike Omega Centauri (the skies bright cluster of this type) 47 Tucanae is much denser toward the core giving the cluster a “3D” appearance in the telescope.
Cartwheel Galaxy by Damian Peach
Submitted July 21, 2015 by Planewave Instruments
CDK20″ with FLI-PL6303E camera. LRGB. L: 60mins. RGB: 5mins.
Located in the southern constellation Sculptor, this collisional ring galaxy was likely formed from a collision between two galaxies in the distant past. The blue ring of material is a region of active star formation dominated by hot blue stars. This ring of material is 150,000 light years in diameter which is larger than our own milky way galaxy. The Cartwheel Galaxy is 500 million light years away and glows at 15th magnitude.

This nebula gets its name from the fact that the main cloud is tri-sected by a dark nebula into three main sections. The beautiful red and blue colors come from the regions of the nebula where hydrogen is glowing (red) and reflecting starlight (blue). The red portion is excited to emission by the ultraviolet light coming from a triple star system embedded within. The distance to the Trifid is approximately 5200 light years, although there is a large disparity between various sources.
