This is Sh2-132 - The Lion Nebula - taken with the Optolong 2" L-eXtreme Filter! This is a dual band filter and I have to say I have been very satisfied of the result I had! After the calibration the colors were quite good and it was not necessary to calibrate them a lot.

Reprocess with a couple extra exposures added to the stack. editing in PS, stacked in deepskystacker 3.4 same kit as before. managed to bring more of the brown/golden dust and blue reflection nebula out as well as the main nebula itself. quite happy with this one i think. :P
This was the first time I'd tried shooting an astronomical object from my back yard in Bend, OR. We're in a neighborhood that has street lights, houses, and a nearby downtown. So I wasn't expecting much when I targeted M42 and its surroundings given all that light pollution. But I was pleasantly surprised.
This was shot with a 90mm f/6 triplet refractor fitted with a field flattener and mounted on an Orion Siriuis EQ-G mount, which was guided with a ZWO ASI120mm Mini Autoguider. I used a modified Canon 6D; no external dual-band or narrowband filter was used. It is only 78 minutes of exposure time (26x180s), yet still revealed a ton of detail. I did take some 10-second exposures to mask into the blown-out core of M42 to reveal the Trapezium stars, but have not yet processed them.
I have acquired another 102 minutes of exposure, which I will add to the data in this image. That should provide a less noisy final composite and bring out even more detail and color.
A first attempt at the well-known triangle of galaxies known as the Leo Triplet.
On the top, NGC3628 aka the Hamburger galaxy; below, M66 and M65.
I'm particularly pleased to have got 3 extra bonus galaxies in the frame: right up in the top-left the tiny fuzzy IC2782, with IC2776 just below and IC2763 in the middle of the left edge of the frame.
Nearly two hours' data, Altair 26C at gain 100 with Neodymium filter, 3-minute subs, and plenty darks+flats+bias calibrations as well.
Another night of clear skies, another DSO. :)
I had already photographed this phenomenal emission nebula a while ago, but with a unmoded Canon SL1. Now I'm revisiting with a Canon T6i astromoded and a light polution filter.
This nebula is AMAZING. The Bok globules (Also known as Thackeray's Globules) are finaly visible.

About M42, the Great Nebula in Orion:
M42 (NGC 1976) is a diffuse nebula situated in the Milky Way Galaxy, 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 located at a distance of 1,344 light-years from Earth, and is the closest region of massive star formation.
Why I like to "play around" with scientific data:
This Feynman quote sums it up...
"Feynman, that's pretty interesting, but what's the importance of it? Why are you doing it?'' ``Hah!'' I say. ``There's no importance whatsoever. I'm just doing it for the fun of it.'' - "Surely you're joking, Mr. Feynman'', by Richard P Feynman.

I mount my Nikon lens and camera on top of my optical tube at the moment. There was a constant wind of ~5mph last night when I took my images. I did 33 light frames and used the best 90% for 30 frames. I polar aligned with SharpCap and began guiding. The graph looked good so I started imaging. The stars seemed to stay in focus so I upped my exposure to 212 seconds and let it go to work. After stacking the files in DeepSkyStacker I pulled the TIFF file into Photoshop and mostly followed along to AstroBackyard's Rosette Nebula tutorial, making some of my own adjustments where they were needed. I'm still struggling with color of the surrounding stars. My WB was set to automatic, that might be why the color is a bit hard to manage. The Moon did rise while I was imaging and I can see a difference in my light frames, I'm sure I can do better and might try again during a new moon. But for my first time trying M101 and autoguiding I'm pretty happy!
Bubble nebula , a favourite of mine, tried several times to capture this well, but only recently managed to improve on it by using longer exposures with the new mount. :) cropped to hide field curvature :P

Data collected in Bazaleti, Georgia on October 5, 2016
An attempt at narrowband imaging. The meade DSI is a bit too old and noisy to take 15 minute exposures that are needed for this nebula's faint outer 'wings' - also my sketchy alignment done manually in photoshop has caused the stars to have strange colour edges. But overall i think its my best m27 to date, quite pleased to have picked up some of the faint wings. Really hope to get a better camera for this kind of work. :)

NGC 1499 a.k.a. California Nebula
...........................................................
Discovered in 1884, NGC1499 is a hydrogen emission nebula which can be found at about 1500 light-years from Earth, in the constellation Perseus, on the Orion arm of the Milky Way. Stretching over a length of 80-100 light years, the California nebula received this name under which it is best known for its shape that more or less resembles the American state of California. The California Nebula is an extremely popular target in terms of astrophotography, images with this target being easy to take with relatively simple equipment. Being an emission nebula, the use of a narrowband filter is highly recommended for better results.

So, that's finally my last capture before I get my DSLR modified for astrophotography.
Of course, my ideia is to shot an emission nebula hard to capture with a stock camera.
If everything ends right, soon I'll post a version of this same target, with some quite similar exposure, but with an astromoded Canon T6i.
Wish me luck!
Well... what a hard target for a Bortle 6 skies and a stock DSLR. Almost 3 hours of exposure and I hardly got some nebulosity. I hope it will change soon, as soon my camera come back and my Optolong L-Pro arrive.
This is an open cluster, close to the Eta Carina nebula. It is already beautiful to the naked eye, showing stars of different colors. But through long exposures, it looks spectacular!
I really think this is one of the most beautiful open clusters in the night sky. The residual nebula that glows in H-Alpha brings an incredible complexity to this DSO.
By the way, I was very happy to be able to record this surrounding nebula. It is much darker than the other nebulae that I am used to photograph, and the heap of stars around it makes it even more difficult.

For some scary summer fun, and with a nod to it being Shark Week on Discovery Network, I shot the Shark Nebula (LDN 1235) in Cepheus. It was first light with my new ASI2600MC Pro cooled astro camera, used with an Orion ED80T (f/6) carbon fiber triplet refractor right from my back yard in Bend, OR. I did not use any filters for this image. The image consists of 123 exposures of 5 minutes each, for a total of 10.25 hrs of integration (this thing is faint)! Light frames and calibration frames were stacked in Deep Sky Stacker, and the combined image was processed using Photoshop and Topaz Denoise AI, and a few of Annie's Actions. This is a first swipe at processing Celestial Jaws. He needs work, but I'll save that for another day.
Prints, cards and more are available via the website: shiny.photo/photo/Sh2-132-The-Lion-Nebula--Cepheus-20c162...
Sh2-132, also known as the "Lion Nebula", is an emission nebula located in the constellation Cepheus. Part of the Sharpless catalog, a list ofH II regions - clouds of glowing gas where star formation occurs.
About 10,000ly distant and 250ly across, Sh2-132 is situated in the Perseus arm of the Milky Way.
The most prominent sources of ionization in Sh2-132 are two Wolf-Rayet stars, which are extremely hot and massive stars nearing the end of their lives. These stars emit intense stellar winds shaping the surrounding gas into intricate structures.
Another of those occasions where one tries to match the DSS image of the Ha emission pattern resembling a lion with how the data looks. Make the OIII too bright a blue and it becomes a cut-'n'-shut with the front and rear ends too separate... It's also about the fine veins and blobs of dark nebulae - lanes of dust in the foreground.
4hr35min total integration with the IDAS NBZ dual-narrowband (Ha + OIII) filter, from which I extracted the Ha & OIII data separately using APP and recombined in PI.

Messier 33 a.k.a. Triangulum Galaxy
..............................................................
As part of the local group of galaxies, along with the Milky Way, Andromeda and several other smaller galaxies, M33 is about 2.7 million light-years away from Earth and can be seen in the constellation Triangulum, a constellation that gave the galaxy its name.
Compared to our galaxy, Triangulum Galaxy is almost 2 times smaller than the Milky Way, with a diameter of about 60,000 light-years, and hosts "only" 40 billion stars, compared to almost 400 billion stars of the Milky Way.
Triangulum Galaxy, according to those passionate about astronomical observations, can be seen with the naked eye (I really couldn’t see it, not even from a Bortle 2 location), but using a small / medium telescope, this galaxy can be seen very well during the last months of the year.

NGC6914 -
If i have this right, this image is a L(Ha+R)GB image. That is, i used .Luminance and RGB filters with a bit of hydrogen alpha mixed with the red channel.
I have wanted to image this area again ever since i first did with my old 350D and the last two clear nights (with no full moon) were the perfect opportunity for me to give it a shot.
It's a nice reflection nebula (blue) in the center of some emission nebulosity in Cygnus.
Used my ED80 - QHY163M - Optolong filters and processed in photoshop.
I'm quite happy with the result, although several different versions of it are on my laptop, some better than others and this one happens to be my favourite for the moment, but that will quickly change :D

M16 come la precedente ma elaborata in HOO.
M16 like the previous one but processed in HOO.
A misty moonlit night was a poor time to try RGB, imaging but without any nebulae in my part of the sky at that time i decided to give it a shot, i chose a star cluster for 2 reasons - bright enough to show up in short exposures, and wouldn't require much stretching during post-processing.

Blue Horsehead Nebula - IC 4592
This is a rarely imaged nebula, located about 400 light years from us, visible in the constellation Scorpio. IC 4592 is a true reflection nebula, being formed of cosmic dust, the central part appearing blue due to the energy released by Jabbah, the star whose light makes this nebula visible. The popular name of this nebula, Blue Horsehead, is given by the more or less obvious resemblance to a horse's head and, as most astronomy enthusiasts know, this is not the only "horsehead" visible in the night sky. Practically every night of the year a "horsehead" nebula can be seen, regardless of whether it is "blue" or "dark". As an additional note, the above statement is valid for the latitude where I am (44 degrees North).

This is my last picture taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY).
This is M64 acquired with Optolong LRGB filters. Small galaxy for my equipment - The photo had been cropped.
I am happy of this result and I hope you like it!!!
Clear skies!

遠眺獵戶
獵戶座是秋冬百看不厭的星座，也蘊藏著不少的深空天體，幾乎每年均會多次拍攝，以測試每次轉變了的器材。今次拍攝遇上了是次冬天最寒冷的天氣，山上溫度曾達到負四度，再加上四五級的大風吹襲，感覺就在零下二十多度的環境中，實在有點吃不消，也只能拍攝廣角深空以對抗寒風。
在嚴寒低溫的環境下，電池的穩定性十分重要，幸好相機及追星儀也用上大容量的外置電池，以應付一整晚的自動拍攝。唯一擔心的是寒風將相機吹倒，所以將腳架的三腳盡量拉開一點，讓她長時間可以陪伴著獵戶。

Nella porzione di Via Lattea che attraversa la Costellazione della Volpetta si trova questo gruppo di nebulose dove spicca Sh2-88 (anche LBN139): si tratta, per lo più, di regioni h-alfa di forte formazione stellare.
Molto elusive, è stata necessaria un'integrazione di 21 ore con pose guidate da 10 minuti con filtro dualband Antlia ALP-T 5nm per la nebulosa mentre per le stelle sono una ventina di minuti di pose da 60 secondi senza filtri. Telescopio newton 150/600 con correttore Tecnosky 0.95x, camera Tecnosky Vision 571C, montatura Eq6-R Pro, elaborazione Pixinsight.
This group of nebulae, Sh2-88 (also LBN139), is located in the portion of the Milky Way that passes through the constellation Vulpecula. These are mostly Hii regions of intense star formation.
Optically very elusive, a 21-hour integration was required with 10-minute guided exposures using an Antlia ALP-T 5nm dual-band filter for the nebula, while the stars required about twenty minutes of 60-second exposures without filters. A 150/600 Newtonian telescope with a Tecnosky 0.95x corrector, a Tecnosky Vision 571C camera, an Eq6-R Pro mount, and Pixinsight processing.
First narrowband mosaic for me.
