This page details images that I've made with my new astrophotography camera, the ZWO ASI294MC PRO.  

The Sony IMX294CJK is the first internal imaging sensor for astronomical cameras to support the Type 4/3 format, producing the pixel output necessary for 4K at 120 frame/s (in ADC 10-bit output mode, the ASI294MC can run up to 25 fps at 4K format base on USB3.0 bandwidth). Additionally, the ASI294MC Pro uses large pixels to achieve SNR1s of 0.14 1x* which is comparable to the ASI224's (0.13 1x*) value.

This camera can cool the sensor up to 35 Deg C below ambient, and is much much more sensitive and noise free than my Canon 60da DSLR.


6/1/2018 My latest image tonight is Messier 81 (also known as NGC 3031 or Bode’s Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to it’s proximity to Earth, large size, and active galactic nucleus (which harbors a supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy’s large size and relatively high brightness also make it a popular target for amateur astronomers. (Wikipedia)

This image was made using my new astrophotography camera and is composed of 29×60 second images. This camera is much more sensitive and the sensor tonight was cooled to 32 degrees F.  I still have a lot to learn about using this camera and Astro Photography Tool software.  These images were made with a camera gain set to 200 then the best 75% were stacked in DSS (Deep Space Stacker) along with 10 dark frames.  I didn't use flat or bias frames.

7/24/18 Last night I imaged NGC 6888. This image is composed of 297 x 15 second which yields 74 minutes of data. I processed it in DSS and Photo Shop.

From NASA: NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. NGC 6888's central star is classified as a Wolf-Rayet star(WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. The nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

9/25-27/2018 Here is M27, the Dumbbell Nebula, imaged over three nights with a total of 5 hours 24 minutes.  This is the first image set taken in the observatory.

Here is another take on the same data:

11/10/2018 Here the Orion nebula (Messier 42) which I've imaged over the last few nights. This represents the best 80% of 9 1/2 hours of imaging. The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula. (Wikipedia)

11/16/18 This is Messier 33 or the Triangulum Galaxy. I've been imaging this galaxy over the last several days and have accumulated over 17 hours of images. This picture represents data post-processed from the best 30% of those images.
The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.

12/4/2018 This I Messier 34 is about 1500 light years away and spans 7.5 light years. This image was taken on 11/20/2018 and incudes 7 hours of imaging.
