I was trying to test my new Optolong L-Extreme filter with a full moon. Unfortunately, clouds rolled in at the 50 minute mark. I was going to scrap the data but ended up playing with it for a bit and ended up pulling out enough for an image.

I first processed it bringing out the reds a lot more but decided to make it a bit more subtle instead. Not bad for such minimal data.

Faint green circular light is surrounding the planetary nebula, though it may be of reflection optical ghost. There look three dark belts probably due to shadow of four vanes at the entrance of the reflector optical tube assembly. A band of shadow is missing. I will image the object again with a suitable APO refractor telescope.

Note: left side of the arc above central bright star WR134 is actually blue, but its very faint hue might be picked up only with O3 filters possibly!

M42, the Orion Nebula, probably the most photographed object in the sky!

It is approximately 1,350 light years away and is the closest large area of star formation to us.

Also in the image is De Mairan's Nebula, M43 and the Running Man Nebula, NGC1977.

It is also one of the few deep sky objects that is visible to the naked eye.

This image was made using a William Optics FLT91 telescope paired with an ASI2600MC Pro camera. 2 hours (240 x 30 second) exposures were stacked and processed using Pixinsight. This is a broadband colour image using an Optolong L-Pro filter.

(Added Ha signal)

Between 5000 and 8000 years ago a supernova exploded in the center of this region in the constellation Cygnus.

Observed from Prachinburi, Thailand.

This is an extremely difficult target for me as I live around 16 miles south of the UK's second largest airport London Gatwick, so battling light pollution from Gatwick and trying to bring out the faint dust is a huge challenge, but I like a challenge and I am extremely happy with the final result

A faint reflection nebula in the constellation of Scorpius..

Sharpless 1 (SH2-1) is a very faint reflection nebula. It is a reflection nebula because it does not emit any light of its own but reflects light from the nearby stars. The magnitude 2.9 Pi Scorpii (which is infact a triple star. Two of the triple stars are hot B type main sequence stars giving the bluish white colour. The distance is approximately 590 light years. The second blue star is 4 Scorpii, is also a bluish white star with a magnitude of 5.5 and distance of approximately 408 light years. Wikipedia says the nebula lies 650 light years from earth.

Not an easy target from Bortle 6 skies but I think quite beautiful.

M81 & M82; are two galaxies located about 12 million light-years away in the constellation Ursa Major. The last time we imaged these objects was over 5 years ago so they were due for a revisit. This image was made over two nights, both of which were curtailed by clouds.

Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy that harbors a 70 million solar mass black hole in its nucleus.

Messier 82 (also known as NGC 3034, Cigar Galaxy, or M82) is a starburst galaxy and is about five times more luminous than the Milky Way with its central region about one hundred times more luminous.

Sh2-91 depuis chez moi à Dounoux, Vosges, France

astrob.in/nzyiqm/C/

Wiki : C'est une nébuleuse en émission visible dans la constellation du Cygne1.

Malgré sa grande taille, Sh2-91 est très faible et son observation est extrêmement difficile, ainsi que sa récupération photographique, qui peut se faire grâce à l'utilisation de filtres spéciaux.

Sh2-91 constitue le filament méridional le plus étendu du résidu de supernova G65.2+5.7, situé à environ 800 pc (∼2 610 année lumière) du système solaire dans une région galactique riche en nuages moléculaires denses, sur laquelle se trouve le Grand Rift. G65.2+5.7 est en fait une superbulle étendue sur environ 180 pc (∼587 al) et située à environ 80 pc (∼261 al)

Cederblad 214 est une superbe et étendue nébuleuse par émission, située dans la constellation de Céphée.

Située à environ 3000 années-lumière, elle s’étend sur environ 150 années-lumière, d’où une taille apparente importante.

Il s’agit d’une zone active de création d’étoiles. Certaines de ces jeunes étoiles sont très lumineuses ; au sein de cette nébuleuse se trouve ainsi l’étoile la plus chaude découverte à moins de 1 kiloparsec (3600 années-lumière) de la Terre, BD+66 1673, dont la température de surface dépasse les 45 000 degrés et dont luminosité équivaut à 100 000 fois celle du Soleil.

Le rayonnement intense de cette étoile est en grande partie responsable de l’ionisation du nuage de gaz qui constitue la nébuleuse. Des dizaines d’autres étoiles contribuent cependant à illuminer le nuage alentour.

De nombreux amas ouverts sont ainsi visibles à proximité de NGC 7822, tels que Berkeley 59 (en haut à gauche de l’image), NGC 7762 (en haut vers le centre) ainsi que dans la région centrale de Sh2-171 (qui désigne plus spécifiquement la nébuleuse sur la droite de l’image).

La région Sh2-171 (ou Cederblad 214) contient de nombreuses nébuleuses obscures, ainsi que des “piliers” de gaz en effondrement, qui donnent naissance à de nombreuses étoiles ; très semblables aux fameux “piliers de la création” qu’il est possible d’observer dans la nébuleuse de l’Aigle (M16).

Flaming Star Nebula

Primi scatti di astrofotografia

Nella cintura di Orione possiamo trovare una delle zone più note e ricca di nebulose che ruotano intorno alla gigante blu Alnitak.

Una grande zona HII dove troviamo la Nebulosa Fiamma, siglata NGC 2024, che in realtà non è illuminata dalla stella Alnitak, come lascerebbe presupporre l’immagine, ma da un ammasso giovane di stelle. La Fiamma in realtà è posta quasi a metà strada tra noi e la Gigante Blu. Sulla destra si staglia una seconda imponente nebulosa siglata IC 434 caratterizzata da una vastissima area HII che mette in evidenza una nebulosa oscura che assume la forma tipica di una testa di cavallo. Questa formazione oscura di gas è siglata B33.

Tra la Testa di Cavallo e la Nebulosa Fiamma, sotto ad Alnitak, si staglia NGC 2023, una piccola nebulosa che brilla per riflessione grazie alla luce prodotta dalla stella HD 37903.

Nel complesso, dal nostro punto di vista, questo angolo di cielo rimane uno dei più affascinanti.

At the top center of the image is the open cluster M18. At the bottom, the red emission nebula is IC1284 and the small blue reflection nebula to its left are vdB118 & vdB119.

Comments

1. Would be better to attempt this as a narrow band target with a mono camera rather than with a OSC

2. am not sure if the focus was consistently good over multiple night- believe I didn't have an autofocuser at that time

IC 63 - The Ghost of Cassiopeia.

About 550 light-years away in the constellation of Cassiopeia lies IC 63, a stunning and slightly eerie nebula. Also known as "The Ghost of Cassiopeia", IC 63 is being shaped by radiation from a nearby unpredictably variable star, Gamma Cassiopeiae, which is slowly eroding away the ghostly cloud of dust and gas.

Shot on a ZWO ASI 2600 MC Duo with a TS Optics 90mm CF APO Refractor telescope. I used .030 welding wire stuck on the front of the lens to make the star spikes that are commonly associated with newtonian style reflectors.

This was imaged over multiple nights, resulting in 24hrs 45mins worth of integration time. For one of the nights I used my Optolong L-Extreme filter to gather more Ha data.

Thanks for looking!
