This was the first proper astrophotography outing for my 100mm. Seeing Andromeda is 2.5 million light years away I am pretty happy with the results. I'd like it to have more light-gathering capability. Chuffed to have captured M32 - a local orbiting galaxy - I bet they are posting better pictures on their version of Flickr.
About 45 minutes of 5 min exposures stacked in deep sky stacker and cleaned up in Ps.

This is my first test with iOptron SkyTracker. Photo was done in NYC.
Light pollution in the New York City is crazy; by naked eyes you can see only some brightest stars (see for example my previous NYC photo on the Flickr). I don’t expect that will be able to get such details of the Orion Nebula.
Original idea was tested tracking of iOptron SkyTracker. For this photo I used Canon 60Da with Canon Telephoto Lens EF 200mm f2.8 L II USM. For 15 second with this lens and fixed tripod I got star tracks. So I decided for testing use exposure 15 second. For this exposure and with such light pollution (and 3 / 4 Moon near Orion) I choose small ISO-320.
Total number of shots was 204 (total time 51 min). I stacked images using DeepSkyStacker, and for post-processing used Photoshop. iOptron SkyTracker pretty much can handle Canon 60Da with 200mm lens and result not even expected for such extreme astrophotography conditions.
Finally got a couple of clear nights :-)
This object is far to the south, and I only have a short time to image it between obstructions, hence the short exposures and high ISO.

The well known nebulosity in Orion's Sword lies 1350 light years away from our solar neighborhood . This huge area of star formation is consisting mostly by hydrogen while the glow of the gas is caused from the energetic stars in the central region, the "Trapezium".
Almost 8.5 years after, I returned back to reprocess one of my very favorite deep sky objects. 52 exposures with different exposure times were combined in order to preserve as many details as possible due to the extended dynamic range. Nonetheless the famous "Trapezium" is unfortunately not distinguishable at this image.
Alignment and stacking took place in DeepSkyStacker and there was a lot of work then as usual in Photoshop.

The diffuse dark Horsehead Nebula (for the astronomers known as Barnard 33), and the 4 light-years wide bright blue reflection nebula NGC 2023 to its lower left, lie both 1500 light years away from Earth. They are part of the Orion Molecular Cloud Complex.
The Horsehead is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gas which is similar to that of a horse’s head when viewed from Earth. The dark molecular cloud is visible only because its obscuring dust is silhouetted against the bright emission nebula IC 434 which is illuminated by the nearby bright hot blue star Sigma Orionis.
The darkness of the Horsehead is caused mostly by thick dust and gas, but also by the complex blocking the light of stars behind it. The heavy concentrations of dust in the nebula results in alternating sections of nearly complete opacity and transparency.

In my view of the Draco Trio you see a close grouping of three very different looking galaxies. There is a spiral galaxy on the top, NGC 5985, the elliptical galaxy NGC 5982, and on the bottom is the edge-on spiral galaxy designated as NGC 5981. All are part of a large group of galaxies called the NGC 5982 cluster. This image is about four hours of collected data.

Galáxia Espiral Barrada M 95
[English Below]
Das poucas galáxias que registrei até o momento, esta é a de menor tamanho aparente. Além de se tratar de um objeto sem grande brilho e tamanho aparentes (visto da Terra), infelizmente a poluição luminosa estava bastante acentuada na direção inicial (e em grande parte do caminho) do alvo, o que prejudicou o registro, dificultando o processamento. Também tentarei fazer mais frames para revelar melhores detalhes em uma próxima oportunidade. Vale o exercício. Este registro contém 2 horas e 36 minutos de exposição.
Messier 95 (NGC 3351) é uma galáxia espiral barrada, com braços quase circulares, localizada a cerca de trinta e oito milhões de anos-luz de distância na direção da constelação de Leão. É uma das galáxias menos brilhantes no catálogo Messier. Fonte: Wikipedia (adaptado).
====================================
Of the few galaxies I have recorded so far, this is the one with smallest apparent size. In addition to being an object without great brightness and apparent size (seen from the Earth), unfortunately light pollution was quite accentuated in the initial direction (and in most of the path) of the target, which impaired the registration, making processing difficult. I will also try to make more frames to reveal better details in the next opportunity. Worth the exercise. This record contains 2 hours and 36 minutes of exposure.
Messier 95 (NGC 3351) is a barred spiral galaxy, with almost circular arms, located about thirty-eight million light years away in the direction of the Leo constellation. It is one of the least bright galaxies in the Messier catalog. Source: Wikipedia (adapted).

The heart nebula, IC1805, is a beautiful object in the northern hemisphere's sky for moderate magnification. Coincidentally, it is actually rather well visible around Valentine's Day, although this specific image was acquired a few weeks earlier (you never know how the weather will turn out...).
The image was taken using the newly-installed William Optics Redcat 71 at the Volkssternwarte München, with an ASI 294 MC Pro camera and IDAS NBZ-II duo-narrowband filter.

So, I’ve been putting off autoguiding for a long time now, after a lot of research, reading and asking a bunch of noob questions I decided to dive into autoguiding this week. I recently purchased a ZWO ASI290MC camera for planetary and moon photography and decided it would make an awesome guide camera when not in use. At the time of purchase, I also grabbed the Canon EOS adapter, why not. The next step was deciding to either go with an off axis guider (OAG) or a separate guide scope. I almost purchased a Celestron OAG and at the last minute decided to try out my Canon 400mm f/5.6 lens as a guide scope.
I had a piggy-back camera attachment for my Meade 12” LX90 and used that to mount the ASI camera and Canon lens to the Meade telescope. I installed PHD Guiding v1.14.2 by Stark Labs (www.stark-labs.com) for the first trial run. I kept all the default setting and was thrilled with the initial results!
I’ve never been able to take longer than 15-second exposures unguided. During this initial run with default settings, I was taking 60-second exposures at ISO 3200 using my Canon 6D DSLR, below is the first light image of the galaxy M82 (28-minutes total exposure taken on February 20, 2017) in the constellation Ursa Major, also known as the cigar galaxy.
Needless to say I can’t wait to image again.
The second run will be using PHD2 Guiding 2.6.3 and possibly using a Canon 100mm f/2.8 lens for guiding. My thoughts are the f/2.8 lens may bring in additional guide stars and also take a little weight off the mount (that I can use for other attachments, lol).
My goal with framing this shot was to include the Dumbbell Nebula (tiny, but bright, on the left), the asterism Brocchi's Cluster (lower right, AKA Coathanger) and some of the well-defined dark nebulae in the region (upper right). Emission nebulae are also fairly prominent near the center.

The NEOWISE pics I've posted so far have been taken via a lens or small telescope on a static tripod, which limited exposure length. With the comet now visible against darker skies as the Moon wanes, I've used a star tracker here to allow longer exposures and therefore to bring out the comet's ion tail, seen here pointing towards the 12 o'clock position. (The thin line to the right of the comet is a satellite track that was on one frame).

Very sad. Missed a couple of clear nights and the forecast isn't looking great so I find myself faffing with old data. Doing that with a CLUSTER suggests that all is not well :)
But then again, ya can't beat a good ol' ultra-colourful, ultra-spiky open cluster :)
Also known as NGC 7822, The Teddy Bear Nebula. Found in the constellation of Cepheus and lies about 2,500 - 3,000 light years away.
Can you see the 3D?
Stare at the middle of the image and try to go cross eyed. You should see a third image start to appear in between the two, whilst going ALMOST cross eyed, try to focus on the middle image.
Any luck?
Still struggling to see it?

This is a planetary nebula in the constellation of Lyra. Planetary nebula are so named because, they are small, round and look like planets.
A planetary nebula is a star entering the final phases of it's life cycle. The more massive stars go out in spectacular style as a supernova. The smaller stars, like that of our Sun. Enter their penultimate phase, that of a white dwarf star, with a little less pazzazz. Though they are no less beautiful.

I was hoping to shoot Comet 12P/Pons-Brooks before it fell below the horizon, but I was overly optimistic. By the time I arrived at my imaging site, the comet was sitting on the western horizon. I had all my gear and nearly clear skies and hadn't imaged in well over a year, so rather than head home, I decided to image something. I chose the Pinwheel Galaxy on a whim. I was able to squeeze the Whirlpool Galaxy into the frame as well.
Instead of using Astro Pixel Processor for gradient removal (my license expired), I used GraXpert for the first time. It worked well, especially considering the cost (free!).

First light with my new Starlight Xpress Trius SX-694 Mono 5 X 600 secs subs in H-alpha 7nm no bias or darks. Clear skies for the first 3 exposures then clouded over for the last 2. Really impressed with just how more sensitive this mono is compared to my one shot colour ccd.

After spending some time on M5 I thought it would be fun to try some widefield Milkyway shots. I had to rebalance and go through the alignment procedure for my scope. I switched the 500mm for a more modest 35mm f/1.4 lens. I decided to shoot it at f/2.8 so it wasn't just wide open and trust my mount that had been polar aligned with SharpCap to do it's thing. I wanted a bright star to help define the area of the sky, so I chose Altair which can be seen in the middle right of this frame and let the gear do it's thing. Images stacked in DeepSkyStacker and processed in Photoshop.
