M42 - THE GREAT ORION NEBULA AND RUNNING MAN - Jan 2021

Ok, this is my final version of this subject for this year. I added another 2 and a half hours of data, to make this a total final exposure of 5 hours.

This is an HDR image created by blending 3 different exposure lengths after stacking and initial processing in Photoshop. It is the first time I've really tried to complete a full HDR image and I think the core of M42 has turned out OK. You can still see detail in the bright Trapezium core region, as well as still seeing fainter details in the outer nebulosity.

I am super happy with the look of this final image, it's muted and has a slightly dreamy colour balance, some will say I've pushed the data too far, but I like it.

Thanks for looking and sharing, comments always welcomed.

Clear skies.

This, I am reliably informed by my software, is the cluster M34 aka NGC 1039, chillin' up there somewhere in Perseus. With some spikes of course, to make it a little less uninteresting. Charles Messier must have had bloody good eyesight!

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth. M57 is the glowing remains of a sun-like star. The star expelled a vast envelope of ionized gas before becoming a white dwarf.

When I first imaged The Nautilus Galaxy (NGC 772/ARP 78) I was fascinated by its shape, one spiral arm stretched outward from the center. This is probably and effect of being tugged on by a satellite galaxy designated as NGC 770 (see the labeled image below). NGC 772 is also listed as ARP 78 in the ARP Atlas of Peculiar Galaxies. This catalog was compiled by Dr. Halton C. Arp and it has 338 peculiar galaxies detailed in it.

It is estimated that NGC 772 is twice the size of our Milky Way Galaxy!

I photographed NGC 772 during three imaging sessions from November 2015 to January 2016. I used a Meade 12″ LX-90 telescope mounted on a Celestron CGEM-DX mount. At prime focus, I placed a Canon 6D DSLR camera right behind my trusty Antares focal reducer. Imaging was done using 20-second sub-frames using mixed ISO settings of 3200, 5000 and 6000. Images were stacked in DeepSkyStacker, stretched in ImagesPlus and final processing in Corel Paintshop Pro and Adobe Lightroom.

A picture of the galaxies M81, M82, and NGC3077 in Ursa Major created by stacking 29 30 second images taken by a Canon 400mm f/5.6 telephoto lens on a Canon 7D MKII dslr camera processed using DeepSkyStacker, Gimp, and Lightroom.

The Owl Nebula, a.k.a. Messier 97, is about 2,600 light-years away toward the bottom of the Big Dipper's bowl. Its round shape along with the placement of two large, dark "eyes" suggest the face of a staring owl.

The Owl Nebula is a planetary nebula, the glowing gaseous envelope shed by a dying sun-like star when it no longer has the hydrogen in its core to fuse into helium. In this state, the star cannot generate energy sufficient to offset the inward pull of its own gravity. The core contracts to an Earth-size mass, as the outer layers expand outwards to seed interstellar space with heavier elements such as the carbon, nitrogen and oxygen. This is one source of raw materials that can eventually be turned into living things, like people. In fact, the Owl Nebula offers an example of the fate of our Sun when it eventually runs out of fuel in another 5 billion years.

The Owl Nebula spans over 2 light-years in space; that's about 2,000 times the diameter of Neptune's orbit.

M30 (NGC 7099) is a bright globular cluster located in the southern constellation Capricornus. M30 is about 27,000 light-years from the Earth. I read an abstract titled “Accreted versus In Situ Milky Way Globular Clusters” by Duncan A. Forbes and Terry Bridges (January 2010) in which M30 is listed as a candidate globular cluster that was stolen from another galaxy at some point in time. The term “accreted” means “come or bring together under the influence of gravitation.”

This image is composed of 32 x 15 second images at ISO 3200 with additional dark and bias frames. Tech Info: Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on September 1, 2016.

About 9.5 hours of exposure over four days using a Tamron 150-600mm lens set to 300mm attached to a Canon EOS 50D(modified). Taken in strong Los Angeles light pollution under the hated light pole. I really need to invest in a light pollution filter but they're expensive...

Night shift today with my son Kevin. The green dot on the top right is the comet "Leonard". It passes the earth only every 80,000 years (!) and is visible this year from late November to early December. Unfortunately the weather is very cloudy, we have been watching the weather forecast for days and saw last night that this morning could be an opportunity with a lot of luck. So we got up at half past four and searched. After about 30 minutes we had found it. Then made a total of 120 pictures each 4 seconds and stacked them with DeepSkyStacker. Lens was the "bokeh master" Sigma 105/1.4.

For this image i wanted to find a workflow with a minimum number of processing steps. I used DeepSkyStacker with the auto white balance (raw) setting so the raw stack already looked good. In Pixinsight the autostretch was transferred to the histogram function followed by slight curves and green reduction with (0.8) SCNR (So no color calibration, no masking, no noise reduction etc.).

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms. (ref: Wikipedia and NASA)

A spiral galaxy in the constellation Camelopardalis.

It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.

Boring techie bit:

An nearby spiral galaxy, only 12 million light-years distant. The active nucleus harbors a supermassive black hole , estimated at 70 million times as massive as our Sun.

This was a test to see what this camera would show of deep-sky objects.
