Ced 51 is an interesting juxtaposition of dark and light, containing dense dark nebula in the foreground abs curing portions of the greater hydrogen nebula flowing in red. Right in the middle is an active star forming region birthing new bright blue stars. Part of the greater lambda orionis ring (head of orion), this nebula complex is approximately 5000 light years from earth in the constellation of Orion, the hunter.

Technically, this was a challenge as to do the area justice, we shot a 4 panel mosaic to frame it right.

NGC 4517 is a spiral galaxy located in the constellation of Virgo. This field is rich in galaxies and if you take the time to peer around you will find many lurking about in the background. The main galaxy in the image displays a quite noticeable dust lane down the center and blue areas which are most likely groupings of young hot stars. NGC 4517 is about 40 million light years from Earth. The galaxy across to the right between 3 and 4 o'clock is NGC 4517A. NGC 4517 in the center of the image is an edge on spiral and NGC 4517A across to the right is a face on spiral galaxy. The two of them make for a fine display.Technical Details:Title: NGC4517 in VirgoObject: NGC4517Photographer: Rodney WattersTelescope/Lens: Tak TSA120 @ F5.6Camera: QSI683 WS8Filters: Astronomik R, G & BExposure: R = 53 x 600” ; G = 33 x 600” ; B = 31 x 600”Total Exposure: 19.5 hoursImage acquisition: Sequence Generator ProProcessing: Pixinsight 1.8.8-5

The Tadpoles Nebula (IC410) and Flaming Star Nebula in the Constellation of Auriga.I took this HaSHO image last week on a very rare almost clear night. In fact it was the clearest night in northern Vermont since last July!. Rather than completing some earlier projects I thought I’d shoot something entirely new, and go for these subjects as they (almost) fit on the same frame at 620mm focal length..The Tadpoles Nebula is so called due to the two light colored tadpole shaped dust and gas clouds that look like they are swimming upwards to the center of the nebula. These are star forming regions, similar to the famous “Pillars of creation” imaged by Hubble in the Eagle Nebula.To get an idea of scale each tadpole is 10 light years long!, more than twice the distance the earth is from its nearest stellar neighbor, Proxima Centauri.To the left is the Flaming Star nebula ( IC 405) which surrounds the variable star AE Aurigae. AE Aurigae is a “runaway” star ejected from gravitational perturbations in the Orion Nebula more than 2 million years ago.Its interesting to note that although these two nebulae appear close together the flaming star is 1500 Light years distant, whereas the Tadpoles Nebula is 12,000 lightyears away and over 100 light years across.This image is processed in the “Hubble Palette where red is aligned with Sulphur emissions, Green with Hydrogen , and Blue with Oxygen .Tech Data : Celestron RASA 11”, CGX Mount, ZWO ASI 6200MMPro cooled (Mono) camera.Ha 12 x 5min, OIII 18 x 5 mins, SII 9 x 5 mins, darks, flats, bias framesSoftware: Stacked in DSS, Processed in Pixinsight and PS 2021

Pythagoras Crater is at the center of this field of view and is a prominent impact crater located near the northwestern limb of the Moon. It has a diameter of 80 miles and is 16,400 feet deep. The prominent central peak rises just over 4,200 feet and is casting a very long shadow that appears to just be touching the western wall of the crater. The rim is well-preserved and the terraced walls are quite apparent. Captured Jan 26 during a full terminator imaging session at 20:28 during the 97.3 % waxing phase.

The complex cloud displays an unusual combination of both red emission and blue reflection areas as well as numerous intricate dark patterns. The nebula is located 9000 light years away in the direction towards the galactic centre. The entire area is sprinkled with thousands of stars and fainter dusty and nebulous areas throughout. A separate prominent dark cloud appears dramatically silhouetted against the starry background to the right.A curious example of gas evaporation can bee seen near the core of the Trifid itself. Here a dense stalk, 8 light years from the centre, is emerging from the edge of the bubble surrounding the central cluster, and in the other direction a powerful stellar jet from a young star, HH 399 embedded in the gas, is shooting out in an upwards direction. The bright young stars in the central cluster emit strong radiation which eats away the surrounding gas and dust. The stalk only appears because a denser region lies at its very tip and protects a thin strip of the cloud from this interstellar erosion. The Hubble Space Telescope has imaged this fascinating area in high resolution: http://imgsrc.hubblesite.org/.../hs-2004-17-a-print.jpg. Throughout the nebula lies countless young T Tauri stars just having emerged from their birthplaces inside the gas and dust. These are typically rather faint and reddish, though they are more easily visible in this image of another stellar nursery near AntaresImage details: Date: May - September 2020Exposure: HaLRGB: 270:916:190:190:195 mins, total 29 hours 21 mins @ -25CTelescope: Homebuilt 12.5" f/4 Serrurier Truss NewtonianCamera: QSI 683wsg with Lodestar guiderFilters: Astrodon LRGB E-Series Gen 2 and 3nm H-AlphaTaken from my observatory in Auckland, New Zealand See Less

This image is a blend of 9 images taken on 9 days from 25.12.2020 to 02.01.2021. This shows how the sunspot AR12794 and AR12795 moves along the solsr disk due to Sun’s rotation. Also noticable is the change in thr apparent size of the sunspots where AR12795 ultimately becomes a faculae. The photo was taken with Nikon D5600, Sigma 150-600c and Thousand Oaks Solar Filter (white light). Post-processed via PIPP, Adobe Camera Raw and Photoshop.

Image Description and Details :

I'm very proud to present this photo in L-HOO which required a total exposure of 27 hours per 20 minutes per photo, spread over 7 nights of the month of May, not counting the 10 hours of image calibration. At a magnitude of 14.74, it is very little luminous, which makes it difficult to image it.

It is located in the constellation Cepheus at a distance of 980 light-years.
Sh2-174 is one of the oldest planetary nebulae that is more unusual because the white dwarf is not in the center of the nebula. This asymmetry is due to the interaction of the planetary nebula with the surrounding interstellar medium.

This image shows the rising Seagull Nebula soaring high above Mt. Druesberg in central Switzerland.

The Seagull Nebula is an emission nebula on the borders of the constellations of Monoceros and Canis Major. Its location 10 degrees below the celestial equator puts it rather low for northern hemisphere observers, which may be the reason why it is not as famous as other nebula that rise higher during the night.

For deepscapes however, a deep space object needs to hug the horizon, which makes the Seagull Nebula a perfect target.

Despite careful planning, the resulting image contains a big surprise: The Seagull Nebula is not that splendid bird with a bright body and wispy wings and tail you can see in this deep image. I didn't even know that these structures exist. What is known as the Seagull Nebula is just the bright body part that remotely resembles a soaring bird on its own - it is the bird in a much bigger, more detailed bird! How awesome!

Another bright planetary nebula to capture during a full moon.
NGC 1501 is a complex planetary nebula in the constellation Camelopardalis.
It's progenitor star is a pulsating star, meaning that its brightness varies regularly and periodically. In the case of NGC 1501’s progenitor star, this is incredibly fast, with the star’s brightness changing significantly in just half an hour.

This portion of the Milky Way in the southern hemisphere is very rich in nebulae and some star clusters, my favorite constellation "The southern cross" with its beautiful stars (Acrux, Mimosa, Gacrux and Imai) are the 4 main stars that they form this constellation which serves to find the south cardinal point by moving the central axis of the "cross" 3 and a half times.

We can also see the nebula of the keel or eta carina and below the cross the sack of coal or head of the "Choique" as the Mapuches knew it.

While taking these photos I was able to observe the passage of the International Space Station next to some Russian polar orbit satellites in the province of Rio Negro.
