Deep sky astrophotography using EAA live stacking and short exposure techniques just right for high-resolution lucky imaging
Welcome - to work out details from deep sky objects and to do high resolution astrophotography with long focal lengths, that's my thing. My telescope is a Celestron C14. Here you will find results of my work. Most of my astrophotography time is spend on deep sky imaging using lucky imaging techniques. This means exposures in the range of 250 ms to 2 seconds per sub. With lucky imaging you do not need an expensive mount, also autoguiding is not needed. ...go to short exposure and lucky imaging techniques
The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a starburst planetary nebula approximately 2,030 light years away in the northern constellation Ursa Major. Taken with my Celestron C14 at about 2462 mm focal length. I used my lucky imaging method, 1 second exposure time, stacked in Autostakkert, usage rate approx. 60 % of images, approx. 180 min exposure time.
The Eskimo Nebula (NGC 2392), also known as the Clown-faced Nebula is a bipolar double-shell planetary nebula (PN). The formation resembles a person's head surrounded by a parka hood. NGC 2392 lies about 6500 light-years away in the constellation of Gemini. Taken with my Celestron C14 at about 3912 mm (F11) maximum focal length. I used my lucky imaging method, 1 second exposure time, stacked in Autostakkert, usage rate approx. 60 % of images.
NGC 2261 (also known as Hubble's Variable Nebula or Caldwell 46) is a variable nebula located in the constellation Monoceros. The nebula is illuminated by the star R Monocerotis (R Mon), which is not directly visible itself, taken with my Celestron C14 at about 2620 mm focal length and the lucky imaging method.
Andromedas Parachute or J014709+463037 is a very interesting deep sky object, a Quadruply Lensed Quasar at z=2.377, 11 billion light years away, taken with my Celestron C14 at about 2620 mm focal length and the lucky imaging method. Cool, the same quasar is shown 4 times by gravitational lensing. The story of the creation of this image you can find it on youtube Andromedas Parachute - through my Celestron C14 telescope maybe you want to watch it. More infos Article regarding discovery
The Einstein Cross (Q2237+030 or QSO 2237+0305) is a gravitationally lensed quasar that sits directly behind the centre of the galaxy ZW 2237+030, called Huchra's Lens. Four images of the same distant quasar (plus one in the centre, too dim to see) appear in the middle of the foreground galaxy due to strong gravitational lensing. Distant quasar Q2237+030 sits directly behind galaxy PGC69457 creating four images of the background quasar due to strong gravitational lensing. The quasar is 8 billion ly away, taken with my Celestron C14 at about 2620 mm focal length and the lucky imaging method. Deep dive CASTLES Survey
The Little Dumbbell Nebula, also known as Messier 76, NGC 650/651, is a planetary nebula in northern constellation Perseus. The special, HST has detected that the central star, a white dwarf named WD 0139+513, is double. For amateur astrophotographer the stars are extremely difficult to separate, at least on my image the pair of stars appears elongated. The second component is slightly fainter than the main star and has a distance of 1.4 arcsec from it, taken with my Celestron C14 at about 2620 mm focal length and the lucky imaging method.

NGC 2857 (also known as Arp 1 and PGC 26666) is a spiral galaxy in the constellation Ursa Major. It was discovered on January 9, 1856 by R. J. Mitchell. NGC 2857 is the first object in Halton Arp's Atlas of Peculiar Galaxies,
and one of six Arp objects in the 'Low Surface Brightness Galaxies' section. Arp 285 below to the right is an interacting pair of galaxies. Both are spirals. NGC2854 is quite a bit larger (65000 Ly) compared to NGC2856 (35000 Ly).
The image was made with ZWO ASI533MC and Celestron RASA 8 f/2.0, taken with my short exposure method 22x 60x 10 s.

M 95 - NGC 3351 found in the constellation Leo, is a beautiful barred spiral galaxy. The central regions of barred galaxies like M 95 (NGC 3351) often include
distinct morphological features in the form of small rings and secondary bars. The rings, known as nuclear rings because of their proximity to the nucleus well inside
the ends of the primary bar, are sites of some of the most spectacular starbursts, shown here in inset. The image was made with ASI533MC and Celestron RASA 8 f/2.0,
taken with my short exposure method 20x 60x 10 s.

Abell 2218 is a cluster of galaxies about 2 billion light-years away in the constellation Draco. Acting as a powerful lens, it magnifies and distorts all galaxies lying behind the cluster core into long arcs.
There are two arcs, z = 1.03 corresponds approx. to 6 billion light-years, z = 0.7 corresponds approx to 6.5 billion light-years. A Redshift Lookup Table for our Universe
The image was made with ASI533MC and Celestron RASA 8 f/2.0, taken with my short exposure method 2340 x 10 s.

NGC 2623/Arp 243 is an interacting galaxy located in the constellation Cancer. NGC 2623 is the result of two spiral galaxies that have merged. Due to NGC 2623
being in the late stage of merging, the compression of the gas within the galaxy has led to a large amount of star formation, and to its unique structure
of a bright core with two extending tidal tails. The image was taken with my RASA 8.

NGC 2685 (also known as the Helix Galaxy) is a lenticular and polar ring Seyfert Type 2 galaxy in the constellation Ursa Major.
It is about 50,000 light-years across and about 42 million light-years away from Earth. It is an object of great scientific interest,
because polar-ring galaxies are very rare galaxies, the image was taken with my RASA 8. The inset is from Hubble Space Telescope (HST).

Arp 322 is a small group of galaxies with a size of 2.1 arc minutes and a magnitude of 14.7 mag, a faint fuzzy. Arp 322 is an interacting group of galaxies in the constellation Usar Major. A four-way interaction going on with a dusty spiral disk onlooker apparently far
enough away from the activity not to be disturbed much by it. This group sits just south of the magnificent NGC 3718. The image was taken with my RASA 8. The inset is from Hubble Space Telescope (HST).
Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies,
compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. The image was taken with my 8" RASA, a 8" Rowe-Ackermann Schmidt Astrograph.
Arp 104, also known as Keenan's system, is entry 104 in Halton Arp's Atlas of Peculiar Galaxies catalog for spiral galaxy NGC 5216 and globular galaxy NGC 5218.
The two galaxies are joined by a bridge of galactic material spanning 22.000 light years. The image was taken with my 8" RASA, a 8" Rowe-Ackermann Schmidt Astrograph.
Arp 224 or NGC 3921 is a interacting galaxy in the northern constellation of Ursa Major. Estimates using redshift put the galaxy at about 59 million light years (18 megaparsecs) away.
It was discovered on 14 April 1789 by William Herschel, and it was described as "pretty faint, small, round" by John Louis Emil Dreyer, size 2.1 × 1.3 arcsec, 13.10 mag. The image was taken with my 8" RASA,
a 8" Rowe-Ackermann Schmidt Astrograph.
Mayall's Object, VV32 (also classified under the Atlas of Peculiar Galaxies as Arp 148) is the result of two colliding galaxies located 500 million light years away within the constellation of Ursa Major. It was discovered by American astronomer Nicholas U. Mayall of the
Lick Observatory on 13 March 1940, size 0.6 x 0.5 arcsec, 15.0 mag. The image was taken with my 8" RASA, a 8" Rowe-Ackermann Schmidt Astrograph.
Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo. One of the most massive galaxies in the local universe.
The core contains a supermassive black hole (SMBH). The jet of matter is ejected from M87 at nearly the speed of light, and stretches 1.5 kpc (5000 ly) from the galactic core.
Messier 82 (also known as NGC 3034, Cigar Galaxy, M82 or Arp 337) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. A member of the M81 Group, it is about five times more luminous than the whole Milky Way and has a center one hundred times more luminous than our galaxy's center.
The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81.
