IC 10 - Irregular Starburst Galaxy
Posted: Sun Jul 16, 2017 10:51 am
Hello,
The Local Group irregular starburst galaxy IC 10. I like the way the HII gas almost overwhelms the blue star burst regions. Data acquired by Phil Massey in 2001 with the Kitt Peak 4.0 meter telescope and made public but him at ftp://ftp.lowell.edu/pub/massey/lgsurve ... ease/IC10/. I’ve reprocessed the data and contacted Phil Massey of Lowell Observatory and asked if I could submit this image to APOD. He said I am welcome to process the data and use as I wish. All image processing from FITS files was done by me in PixInsight 1.8 and Photoshop 2015.0.1.
Blue: 60 seconds
Green: 60 seconds
Red: 50 seconds
HA: 300 seconds (combined as usual with Red to create a single layer)
If you choose to use, please give both of us credit:

The Puszta at Night
Copyright: György Soponyai
That night was an ideal one for some wide field astrophotography. The New Moon, the crystal-clear skies and the moderate light pollution led me out to this well near Kiskörös at the border of Kiskunság National Park. This kind of old draw well is the symbol of the Hungarian Plain, the Puszta.
2014.03.01. Kiskörös
Canon EOS 5D Mark II + Carl Zeiss Distagon 28/F2.8
20 sec, F2.8, ISO3200
Well..
This was the original story. I discovered that wonderful well more than three years ago and took the picture above on the night of discovery. Since then I have been roaming there many times: a silhouette as a perfect, strong foreground with low light pollution. However on my last trip I just realized that the owner of the area had demolished the well and cut down the tree!
By recutting and desaturating the photo I just would like this place not to be forgotten.

NGC 6715 / Messier 54
NGC 6715 / Messier 54 by Terry Robison, on Flickr
This dense and faint group of stars was the first extragalactic cluster ever discovered. It was given the name of M54 by the famous astronomer Charles Messier in 1778. It was also observed on Jun 2, 1826 by James Dunlop, and by John Herschel on July 31, 1834. This cluster is fairly easy to locate with a modest instrument. It can be observed with either binoculars or a small telescope. Expect to see a round and hazy patch of light. Even larger amateur telescopes cannot resolve it into individual stars. The best time of year to observe the cluster is during the months of June, July and August.
It is estimated to be around 90,000 light-years away. This is more than three times as far from Earth is to the galactic centre. It covers an area of 12 arc minutes, and has a true radius of 153 light years. It is also one of the denser globular clusters known, and has a density classification III.
In 1994, an exciting discovery was made that M54 was probably not a member of our Milky Way at all. It was a newly discovered dwarf galaxy. This galaxy is now called SagDEG, for Sagittarius Dwarf Elliptical Galaxy, and is one of the most recently discovered Local Group galaxies.
Currently, this globular cluster is now understood to lie outside the Milky Way, but it may actually become part of it in the future. The strong gravitational pull of our galaxy is slowly consuming the Sagittarius dwarf galaxy. In the end, it will eventually merge with the Milky Way, creating a much larger galaxy.
Blue hook stars were another interesting discovery within M54. They belong to a rare class of horizontal branch stars (stars with masses similar to the Sun’s in the stage of evolution immediately following the red giant branch) that go beyond the lower limit of the envelope mass of canonical horizontal-branch hot stars. Blue hook stars have been detected in very few galactic globulars. They have been observed in Omega Centauri, NGC 6273, NGC 2808 and NGC 6388.
Center (RA, Dec): (283.765, -30.481)
Center (RA, hms): 18h 55m 03.714s
Center (Dec, dms): -30° 28' 50.898"
Size: 45.3 x 30.1 arcmin
Radius: 0.460 deg
Pixel scale: 0.804 arcsec/pixel
