Testing with the new Optolong L-synergy filter

a 7nm dual-band S2 O3 filter

which allows you to combine shots with the classic HA O3 dual-band filters and create a composition in the Hubble Palette using an OSC color camera.

The Heart Nebula IC1805, taken with the L-synergy filter, was also truly impressed with the amount of O3 present and its clarity. The filter is free of halos and gradients, making post-processing very easy.

Thanks to Optolong Astronomy Filter for giving me the opportunity to test this filter.

I could enjoy imaging of the SNR with my old telescope and another duo-narrowband filter. STC Astro Duo-Narrowband filter has a bit wider 7-12nm bandwidth compared to Optolong L-ultimate filter 3nm, but result was not so much different. Both were nice.

After preprocessing in Nebulosity and initial registration and stacking in PixInsight, I combined the RGB channels first. This at least brought out some color before I started layering in the luminosity channel. Continued processing in PixInsight and final touches in Photoshop. I feel like I need to go back and add some H-alpha when I get a chance.

The first image of 2023, and because Orion is already setting relatively early, it made sense to revisit M42, The Orion Nebula. This shot is a composite image made from three different exposures and stacked separately. The lower exposure images were then blended with the higher exposure image to reduce the overexposed regions to just The Trapezium Cluster (the asterism of six very bright, young stars in the central region).

[Summarised From Wikipedia] The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated approximately 1,344 light-years away in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky. M42 is the closest region of massive star formation to Earth and is estimated to be 24 light-years across.

The Orion Nebula is visible with the naked eye and is seen as the middle "star" in the "sword" of Orion, which are the three stars located south of Orion's Belt. The "star" appears fuzzy to sharp-eyed observers, and the nebulosity is obvious through binoculars or a small telescope.

Just as The Trapezium Cluster is a component of the much larger Orion Nebula, so the Orion Nebula is in turn surrounded by the much larger Orion molecular cloud complex which is hundreds of light years across, spanning the whole Orion Constellation.

L'amas de la Chouette ou « E.T. Cluster » (NGC 457 ou Caldwell 13), est un très jeune amas ouvert situé dans la constellation septentrionale de Cassiopée. Cet amas d'étoiles a été découvert par William Herschel en 1787. Il renferme quelque quatre-vingts étoiles et sa distance au Soleil est estimée à ∼7 920 années-lumière. Les dernières estimations donnent un âge de 21 millions d'années à cet amas. Sa taille apparente est de 20,0 minutes d'arc, ce qui, compte tenu de la distance, donne une taille réelle maximale d'environ 46 années-lumière.

NGC 2264 Christmas Tree Cluster/Cone Nebula

NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster. Two other objects are within this designation but not officially included, the Snowflake Cluster, and the Fox Fur Nebula.

All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2,600 light-years from Earth. NGC 2264 is sometimes referred to as the Christmas Tree Cluster and the Cone Nebula. However, the designation of NGC 2264 in the New General Catalogue refers to both objects and not the cluster alone. (Wikipedia.org)

In the Cepheus constellation there are vast nebulae complexes, some of them of dark nature, and this one - LDN (Lynds Dark Nebula) 1235 - is quite well known due to its resemblance to a shark.

These dark nebulae are opaque clouds of dust and gas blocking the light of the stars behind. But some of this dust has some bright due to photoluminescence, a phenomenon in which the dust and gas are hit by high energy radiation and exhibit glow due to it.

In addition, two reflexion nebulas can be seen - van den Bergh 149 (vdB 149) and vdB150. These are the two blue areas near the center and its color arises from the two hot stars nearby which illuminates the dust around them.

This image is my first case where data from two different years was used. In 2021 some RGB data was collected but I didn’t feel it was enough for a good image but I had no opportunity to shoot again back then. This year I took some luminance data to complete it and take it out my WIP list… :D

These 12 images were shot on 2022-07-15 from 0941 through 1011 UT; all data taken with a Celestron Edge HD 925 with a ZWO ASI120MM and Optolong RGB CCD filters; image scale is 0.078" per pixel

Images compiled from SER files with R, G, and B filters; best 35% from each file were stacked in AutoStakkert with 2.0x resample option; the resulting mono images were sharpened in PixInsight, then rotated and cropped in Photoshop; video rendered in Photoshop. Images were not derotated in WinJupos as I wanted to see what would happen if I just stacked the channels.

The effect you get with Io brightening dramatically is due, I think, to the fact that Jupiter's limb is facing at an angle to us while we are still getting the full reflectivity of the side of Io facing the Earth.

So, da ist es nun, mein erstes "besseres" Astrofoto mit meinem Teleskop.

Ich muss mich natürlich erstmal noch ein wenig in die Bearbeitung von Astrofotos reinfummeln. Aber fürs erste denke ich "nicht schlecht". Vermutlich werde ich in 2-3 Jahren das Bild sehen, die Hände über dem Kopf zusammenschlagen und denken "ach Du sch...". Aber ich finde, ganz vergeigt hab ich es nicht.

Das Bild zeigt den Elefantenrüsselnebel IC 1396 A, ein Sternenstehungsgebiet in 2400 Lichtjahren Entfernung.

Also das was man da auf dem Bild sieht ist der Zustand des Nebels vor 2400 Jahren, 375 Jahre vor Christi Geburt.

Das muss man sich mal reinziehen. Obwohl es gibt natürlich Motive die deutlich weiter weg sind...

Sh2-129 is a large emission nebula visible in the constellation Cepheus. It is also known as the Flying Bat Nebula. Its distance has been estimated at around 1,300 light-years. The Squid Nebula, cataloged as Ou4, is barely visible—a truly difficult subject! The image shows the faint emission from the oxygen III atom it is composed of.

The perspective makes them appear very close, but they are very distant. To their right is the Seahorse Nebula, a dark nebula immersed in the dust of Cepheus.

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.
