A menacing cloud of gas and dust looms in the southern constellation of Ara, seemingly depicting a scene of two dragons fighting above a glowing egg. This is NGC 6188, an emission nebula also known as the Rim Nebula, and NGC 6164, a bipolar nebula. This image was shot in Ha, as clouds came in during Oiii data acquisition.
Captured in Singapore under class 8 skies.
My first Jupiter image built from separate R, G, and B channels. Imaged with a Celestron Edge HD with 2x Barlow, ZWO EFW filter wheel, ZWO ASI120MM camera, and Optolong RGB filters. Recorded in SharpCap 3.2, then stacked in AutoStakkert 3. Initial wavelets in PixInsight, then channel derotation and combination in WinJUPOS. Brought the resulting RGB image back into PixInsight for some sharpening and color correction, then some final touches in Photoshop.
Stacks were shot from about 2:00am to 2:35am local time. Jupiter was at a distance of about 612 million km (34.0 light minutes). It was at an altitude of about 43° from my backyard in Long Beach, CA.
This image is centered on Alnitak, a very bright star in Orion’s ‘belt’ 1,260 light-years from earth.

ear the well known Dumbbell Nebula, in the constellation Vulpecula (the Little Fox), lies a lesser known emission nebula named Sh2-86, listed in the Sharpless catalogue. This area is an active star formation location, which can be seen by the young cluster (NGC 6823) within the bluish oxygen rich nebula near the center and, nearby, small black clouds called Bok globules are the material from which a star may emerge.
This image is a cropped and rescaled version of my previous image of this area, focusing in the brighter and smaller details. Secondary effects of lack of new data... 😊

The incandescence of the Eagle Nebula is laced with intricate dark lanes, globules, and huge clouds of dust which shroud ongoing star formation from direct view. The most prominent dark structures are the so-called “Pillars of Creation”, three long fingers of gas and dark dust nearly ten light years long. The Pillars are a field laboratory for the study of star formation and have been examined intensely by astronomers at visible, infrared, and ultraviolet wavelengths. Within the Pillars are much smaller, warmer, and denser regions called evaporating gaseous globules (EGGs), some of which contain just a few solar masses. The EGGs are ground zero for star formation, though it’s difficult to catch these new stars in the act of igniting because they remain obscured by cloaks of dark dust. EGGs located near bright stars are elongated by winds of light and charged particles into what look like schools of celestial tadpoles.
The stars within the Eagle Nebula appear to be in an intermediate state. Stars within the Pillars and other dusty regions remain obscured, while a cluster of some 400 new stars clearly appears in a more transparent section of the nebula. The largest of these stars has a mass some 80 times that of our Sun and the luminosity of perhaps a million Suns. The cluster formed just 2 to 5 million years ago. The nebula itself is only slightly older.
The light we see from the Eagle Nebula and its associated stars left some 7,000 years ago, but some astronomers suspect the Pillars of Creation may have already been obliterated when a massive young star within the nebula detonated as a supernova. The Spitzer Space Telescope detected evidence of a patch of hot gas near the Pillars which may have been caused by such an event about 8,000 years ago.

Messier 106 and Friends
Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole. NGC 4217 is a possible companion galaxy of Messier 106.

Tarantula Nebula is an impressive cosmic object, it lies in Great Magellanic Cloud, a nearby galaxy of our local group. This nebula is very rich in hydrogen, in this image we can see many complex clouds of ionized gas. NGC 2070 is a jewel for southern astrophotographers and I'm feeling so happy with this work. It's always a challenge to get this nebula because it is high on sky in rainy season here in Brazil.
Besides that, it was a great pleasure to do this work because there was a cooperation between Rick Stevenson and me sharing our h-alpha images to improve exposure time.

Recently, I sent a set of remote equipment to Yunnan province. Before my new telescope arrived, I borrowed a 130 f/2.8 HNT from SharpStar and tested it with my new QHY268M camera and Optolong LRGB filters.
The six-panel is the result of the test photography in February.
Top left: the famous Orion Nebula M42/43, located below the belt of the hunter, about 1350 light-years from Earth, the nearest star-forming region.
Upper center: the Witch's Head Nebula IC 2118, located to the lower right of Orion, about 900 light-years from Earth, a patch of dust illuminated by Rigel.
Upper right: the Seagull Nebula IC 2177, about 3,700 light-years from Earth, with a wingspan of more than 100 light-years, soaring between the constellations Monoceros and Canis Major, consisting of a large cloud of hydrogen and dust, containing a large number of newborn stars.
Lower left: The Black Eye galaxy M64 in the constellation Coma Berenices, about 24 million light-years from Earth, slightly smaller than the Milky Way, is the result of the merger of two galaxies; the surrounding faint nebula is the dust in the Milky Way.
Lower middle: DIR 198+32, an indescribable faint cloud in Cancer, even can't find much information, it should also be the molecular cloud in the Milky Way.
Lower right: A small patch of the Virgo cluster contains a number of galaxies, notably M100 on the upper left, NGC 430/4298 on the left, M99 on the left of center, M98 on the right, and NGC4216 on the lower, all more than 40 million light-years from Earth. The largest, M100, is 55 million light-years away and has a diameter of more than 100,000 light-years. It is about the size of our own Milky Way and is one of the largest and brightest members of the Virgo-Coma Cluster. The bright star right in the center, with a good number, HD 106888.
Now my new telescope is in place, with a 10-inch aperture and 1-meter focal length, it's time to start another round of testing.
Stay tuned!

Kemble’s Cascade, also known as Kemble 1, is an asterism in the constellation Camelopardis named after Lucien Kemble, a friar who spotted it with its binoculars. It is formed by about 20 stars in a straight line with a length of 3 arcseconds (about the same as 5 times the Full Moon apparent diameter); on one end the open cluster NGC 1502 can be seen. These stars are not related and their alignment happens by coincidence.

Caldwell 9 Diffuse Nebula in the Constellation Cepheus
Sh2-155 (also designated Caldwell 9, Sharpless 155 or S155) is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. It is widely known as the Cave Nebula, though that name was applied earlier to Ced 201, a different nebula in Cepheus. Sh2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 725 parsecs (2400 light-years) from Earth. (Wikipedia.org)

Processing some lost data from last year! This is IC 59 and IC 63 and are found in the constellation Cassiopeia very near the bright star Gamma Cassiopeia. This set of objects is also known as the Ghost of Cassiopeia. Gamma Cassiopeia also has the informal nickname of Navi. The “IC” designation comes from a group of objects discovered between 1888 and 1907, most made possible by photography, and known as the Index Catalog.
These nebulae are a combination of emission and reflection, they are located about 610 light years from Earth and are about 10 light years across. Gamma Cassiopeia provides the radiation to light up this area of dust and gas, eventually dissipating in the area.

Description: This image of the Elephant’s Trunk Nebula IC 1396 was developed from 37x300s subs or 3.08 hours of total exposure time. A dual bandpass integrated image was first separated into Starless and Stars only images. The Starless image was split into its RGB components, which were individually boosted as appropriate, followed by the application of appropriate weighting factors to the individual RGB channels, further followed by LRGB Combination. The resulting image was then recombined with the Stars only image the result of which was post processed with various color masks using Curves Transformation to generate a final image.

Taken with my new portable setup: AM5 mount, Radian Raptor 61, EAF, AsiAir plus, ZWO2600mm and optolong filters. Mostly from bortle 1-2, with about 20 hydrogen frames from Phoenix, bortle 9. After seeing other shots, I really liked bringing out the wispy hydrogen clouds in the foreground. I really pushed the stretching to get this far on it. 15 hr 14 min integration time.
SH2-115 is a large emission nebula found in the northern regions of the constellation Cygnus, about 2° northwest of the bright star Deneb. Located about 7,500 light-years away, this extensive HII region is broken into two basic parts - one being roundish and associated with a bright cluster known as Berkley 90- which is shown in this SHO rendering to be a mix of blue and red colors. The other section is a long linear feature that is shown in red in this rendering.
Also in this view is Abell 71 (Pk 85+04.1). This is recorded as a faint planetary nebula with a magnitude of 18.9 central star.
The Leo Triplet (M65, M66, and NGC 3628) is a small group of interacting galaxies about 35 million light-years away in the constellation Leo.

Popularly known as the Dolphin Head nebula, SH2-308 in Canis Majoris is an expanding shell of hot gas expelled by its central star. The nebula does show some red light from hydrogen ions but it is dominated by the blue emission of oxygen ions.
This widefield shot also shows red hydrogen emission nebulae in the Dolphin Head's neighbourhood.
This image is a stack of over 6 hours of data taken on an IR-modified Canon 700D camera with a William Optics Redcat51 telescope. I used an Optolong L-eXtreme dual band filter to improve the contrast of the hydrogen and oxygen ion emissions. All post-processing was carried out in PixInsight.
Observed from Prachinburi, Thailand.
