M15 Globular star cluster.

 

First discovered in 1746 by an Italian named Jean-Dominique Maraldi. It's approximately 33,600 light years away in the constellation of Pegasus. M15 is one of the densest clusters yet discovered with many very hot blue stars and many of the cooler orange stars becoming more concentrated towards the core.

 

It was the first of only four globular clusters found to be hosting a planetary nebula. The one in M56 is named Pease 1, after it's discoverer Francis G. Pease in 1928.

It's also thought to contain a black hole at it's core, estimated to be 4,000 times the mass of our Sun.

 

I also had a little play with the 3D module in StarTools. It looks great using the cross eyed method, but when I save it then try loading to Facebook, it doesn't come out very well sadly.

 

Took the image with a Skywatcher 8" quattro and a Canon 1100D. Along with some other bits n bobs and lots of images stacked together. Processed everything together with DeepSkyStacker & StarTools.

- Deneb, from Cygnus constellation (bottom left)

- Altair, from Aquila constellation (middle right)

 

This picture has been obtained stacking 5 images of 5 minutes exposure each. Of course, an equatorial mount was used to offset the Earth rotating motion.

 

A 18-55 mm kit lens mounted on a Canon 600D camera were also used.

Had a session on M42 the other night whilst testing the guiding on the QHY5 I've just acquired (works), and having done M42, and done it again, and again, I thought I'd drizzle into this. Only 19 subs before it disappeared behind a tree, so very noisy, but colourful nonetheless :) I really need a longer focal length, and a lot more subs, to do this justice.

 

Designated NGC 1973, 1975 and 1977 (the seventies), but more commonly known as The Running Man Nebula, this is just north of M42 in Orion.

The Rosette Nebula is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of some 5,200 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. (Wikipedia)

I've always been fascinated how the Andromeda Galaxy M31 and the Triangulum Galaxy M33 form an almost straight line with the bright star Mirach (beta Andromedae), which also lies nearly symmetrically in the middle between these galaxies of our local group.

 

I choose this motif to try out my newly acquired (though used...) Canon 50 mm f/1.4 - something I didn't have in my lens collection so far. I'm quite happy about both the brightness of the image, and about the good star rendering until about 80% radius from the image center. Outside, there's some coma, but not too bad, and stopping down a little to f/2.2 helped a lot (and is still rather fast!).

 

I was surprised how much detail of the galaxies is already rendered by a 50 mm lens. If you look carefully, you can even spot the dwarf galaxy Mirach's Ghost (NGC 404) next to a diffraction spike of Mirach approximately at the 4 o'clock position.

A target I've been wanting to image for a long time, never had enough focal length until I recently had access to a 400 2.8 from Canon.

 

Shot using stock Canon 6D, EF 400mm 2.8 IS III and Skywatcher EQ6R Pro (unguided)

 

Imaging with stock cameras isn't ideal, thermal noise is a real problem after the exposure times needed. The longer exposures needed to get a reasonable signal really heats up the uncooled sensor. Mine during these summer months has hit 35-40c regularly which creates awful noise.

 

Getting as much data as possible helps lower these issues, but doesn't eliminate it. However, shooting with modern DSLRs does result in achieving star colour relatively easier compared to 12 and 14bit astro cameras.

 

This image is comprised of 21x600s Ha and 24x60s RGB exposures.

This is part of the area designated IC 1396 in Cepheus, which includes The Elephant's Trunk Nebula, at the bottom, looking a tiny bit like an elephant's trunk :)

 

Long time since I did a collaboration with my frozen northern buddy Dave Williams. This is 5 hours of 300 second subs @iso 800 for the RGB (mainly R!) and Ha kindly provided by Dave and used as luminance.

 

A little noisy in places - the DSLR RGB input provides that, so not a lot I can do about it until the next kit upgrade on 12th Never. :)

I went back out for a third time this week to re-attempt an equatorial alignment, bearing in mind some lessons learned and settling for a shorter camera lens focal length rather than the full 1350 mm of the telescope, but still struggled with tracking errors. Not really sure what I'm doing wrong, maybe the equipment I have just isn't up to the task. I shot this with 90-second exposures, at 180 mm, and recorded 30 frames, but only 10 proved usable. The rest had varying amounts of trailing, and even most of the 10 had a small amount. Longer exposures were faring even worse. Bit annoyed to only get 15 mintues of data from 45 mintues of recording, but with some enthusiastic processing in DeepSkyStacker and Lightroom, I managed to make something of it anyway! Thanks to the extra-dark West Texas skies and the tracking mount I was finally able to get a half-decent image of the Heart and Soul Nebula(e). This was 10 frames at 90 seconds, f/3.5, 180 mm, ISO 2000.

An unguided image of the Double Cluster in Perseus taken last night through a Canon 400mm f/5.6 L lens using a Canon 7D MKII dslr camera mounted on a Celestron AVX mount. Ten 30 second images and four dark frames were stacked using DeepSkyStacker and then enhanced with Adobe Lightroom.

 

I added another half hour of imagery to what I already had, so this image consists of 65 minutes of data. After shooting it this latest time, I realized that I hadn't been balancing my tracker correctly when shooting south, so when I image it again this fall, I hope to be more efficient with getting non-star-trailed 60-second subs.

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. It is sometimes incorrectly called the "North American Nebula".

Messier 12 (M12 or NGC 6218 in the New General Catalog) is a globular cluster in the constellation Ophiuchus. It is also referred to as the “Gumball Globular”. It was discovered in 1764 by the French astronomer Charles Messier who described it as a “nebula without stars”. M12 is approximately 15,700 light-years distant. You will definitely need binoculars or a small telescope to see this cluster. This cluster contains about 200,000 stars, the brightest of them are about 12th magnitude.

Here is an image I took on the evening of December 27, 2016 of this large, but faint galaxy called the Sculptor Galaxy (also known as NGC 253, Silver Coin or Silver Dollar Galaxy). This was my first time imaging this galaxy and I couldn’t believe how large it was, nearly filling the camera view (I’ve been imaging planetary nebula, so left the focal reducer off). With the high winds and clouds rolling in, this is what I ended up with.

Tech Specs: This image is composed of 68 x 15 second images at ISO 5,000 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on December 27, 2016 from Weatherly, Pennsylvania.

Working on the assumption that I'm unlikely to add to this in 2012, these are my efforts for the last 12 months :)

 

2012 was not a good year weather wise, even by UK standards. I struggled to find 12 images to go in this, but that could be down to the fact that I tend to spend more time on each image these days. Anyway, thanks for all your kind comments and faves over the last year, and I wish you all a peaceful Christmas, and a multitude of clear skies in 2013 :)

Andromeda galaxy shot from my driveway on a dark autumn evening. This is the only benefit I see from changing the clocks back... earlier night sky viewing. 5 images (300mm - 30 seconds each) on an iOptron SkyTracker stacked in DeepSkyStacker to reduce noise.

Another collaboration with my northern buddy, Dave Williams, who once again kindly provided the Ha, which was used as luminance. I also layered in the M42 I did earlier this year to improve the colour. This again demonstrates just how much the ED80 leaves the 200p in its wake :)

There's a few galaxies in this. Apart from all the chunky ones, there are loads of little fuzzy ones as well. Cool. Not quite Hubble Ultra Deep Field, but not bad from my back garden :)

 

This is part of the Virgo Supercluster of galaxies, which comprises as many as 2000 galaxies. Our Local Group, which includes us (the Milky Way) and Andromeda, is in the suburbs of the Virgo Supercluster.

 

This is just over 7 hours of ten minute subs for luminance and 2.5 hours of 5 minute subs for the RGB, what there is of it!
