View towards the center of our galaxy.

The super-massive black hole lies at the lower central part of this composite image.

Pentax K-3 II was mounted on Vixen Polarie. I used Tamron 17-50mm f/2.8 XR Di II LD set at 50mm.

The night was relatively hot, so I was obliged to take many exposures and I tried various settings for the exposure, aperture and ISO.

The best 58 out of 65 RAWs (DNG) were aligned and stacked in DeepSkyStacker. Further processing took place in Pixnsight LE (artificial flat frame subtraction) and CS3 (levels, curves, selective color, brightness and contrast, saturation, correcting the imperfections of the stars at the corners due to coma).

The total exposure time was almost 31.7 minutes.

Globular Cluster Messier 80 (M80 or NGC 6093) is a globular cluster that can be found in the constellation Scorpius. This cluster was photographed in July 2015 and the final image is a stack of 18 thirty-second exposures (nine minutes total) at ISO 3200 using a Canon 6D at prime focus of a Celestron 6″ telescope. The imaging system was mounted on an iOptron ZEQ25 equatorial mount for guiding.

M80 lies at a distance of about 32,600 light-years. It is one of the densest globular clusters in our galaxy. Software used to create this image include DeepSkyStacker (for stacking the individual frames), ImagesPlus (for initial stretching and post processing), and Corel Paintshop Pro X5 and Adobe Lightroom for the final image adjustments.

From last Friday night/Saturday morning, when I only managed 6 increasingly clouded frames before it became totally overcast.

A planetary nebula is so-called because they looked like a planet to early telescope-users. In fact they form when a star blows away its outer layers in a nova.

6 x 4-minute exposures at ISO 1600, f/4. Manually guided off-axis. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.

One of my favorite targets - the integrated flux nebula (IFN) or galactic cirrus is faint dust illuminated by our galaxy, and there happens to be a nice concentration of it in the direction of Bode's Nebulae (Bode's (M 81) and Cigar (M 82) Galaxies). The Angel Nebula, which is made of IFN, is in the lower left corner. This is an improvement over my last attempt at this target - shooting raw and more integration time made a difference.

Nov 2020 update: The color of M 81 on my original version had always irked me a bit. I reprocessed it and now M 81's color is much better (in my opinion).

Using my 170 exposures of my Star Time lapse, I've stacked the images using DeepSkyStacker. Helping the brightness of the stars to come through.

I'm currently shooting at 30sec exposure and ISO100, can I increase my ISO levels by using Dark noise reduction to see more of the night sky, ie The Milky Way?

The Jellyfish Nebula (left-center) is a supernova remnant. The Monkey Head Nebula is the bright emission nebula near the bottom; the monkey head is upside down looking right here. Both are quite close - the Jellyfish Nebula is an estimated 5,000 light years from earth; the Monkey Head is an estimated 6,400 light years from earth. The large star cluster near the top is Messier 35 (NGC 2168). NGC 2158 is the other smaller star cluster to the lower right of Messier 35.

PicA guided image of the spiral galaxy M106 spiral galaxy in the constellation Canes Venatici and six of its galactic neighbors. From left to right and above M106 are NGC 4220, NGC 4231, NGC 4232, NGC NGC 4248, NGC 4217, and NGC 4226. The image was taken with a Canon 400mm f/5.6 L lens on a Canon 7D MKII dslr camera and a 30mm Svbony guide scope with a ZWOASI224MC guide camera. The final image was created from 18 115 second images combined together with Deepskystacker and enhanced with Gimp and Adobe Lightroom. M106 is 25 million light years away from Earthture saved with settings applied.

Added some more subs to this last night (4th clear night on the trot - I MUST get some sleep!) so it's now 1 hour 24 minutes. Better colour I think and I took a little more care over the processing. Also redid the core at 4 seconds.

"The night starts here, the night starts here, forget your name, forget your fear

The night starts here, the night starts here, forget your name, forget your fear

The pleasure part, the afterthought, the missing stone in the graveyard

The time we have, the task at hand, the love it takes to become a man

The dust at dawn is rained upon, attaches itself to everyone

No one is spared, no one is clean

It travels places you've never been or seen before

The night starts here, forget your name, forget your fear

You drop a coin into the sea, and shout out "Please come back to me"

You name your child after your fear, and tell them "I have brought you here"

The scary part, the aftershock, the moment it takes to fall apart

The time we have, the task at hand, the love it takes to destroy a man

The ecstasy, the being free, the big black cloud over you and me

And after that, the upwards fall, and were we angels after all?

I don't know, I don't know...

The night starts here, the night starts here, forget your name, forget your fear

The night starts here, the night starts here, forget your name, forget your fear

You drop a coin into the sea, and shout out "Please come back to me"

You name your child after your fear, and tell them "I have brought you here"

The night starts here..."

Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 41 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken Jan 10, 2019.

This is a reprocess of data from earlier in the year - this time I used the 'remove light pollution' and 'HSL selective color' tools of Astro Pixel Processor after integrating light frames in DSS and before editing in GIMP. Also, my flats were introducing artifacts so I didn't use them, but instead corrected vignetting with the 'remove light pollution' tool.

I'm much happier with this version - the color and definition of the nebula are much better, and seem to be accurate in comparison with other images.

M57 aka NGC 6720 is a Planetary Nebula (nothing to do with planets - long story) and is the outer shell of a red giant star that's coming to the end of its life and expelling its outer gasses (or something like that)

Another M bites the dust, and what a piddling little thing this is! Barely bigger than a fat star, I used 3 x drizzle in DSS so that I could actually see the thing. Not best imaged with an ED80 and budget kit, that's for sure. Never done a PN before :)

Messier 3 (aka M3 or NGC 5272) is a globular cluster in the constellation Canes Venatici. At 34K lights years from Earth, it is about 8 billion years old and contains about 500,000 stars.

I find globular clusters quite difficult to process, and this was no exception. This was about my tenth iteration, and my last unless I add more data to it. 79 x 3 minute subs @ iso1600.

I'd like pinpoint stars, but that ain't gonna happen with a DSLR :)

Spent a good amount of time recently testing a bit of kit that effectively converts my EQ5 to a Goto, and now using EQMOD in conjunction with PHD for guiding. Working well, and for £90 (and in the true spirit of budgetastro) I'm more than pleased :)

Found this cluster while I was zipping around the heavens playing with the Goto, and fell in love with it. M35, aka NGC 2168 in the foreground, is about 2.8K light years away, quite young at 150m years (hence the blue stars) and contains about 2500 stars. NGC 2158 (above right of M35) is about 10K lights years away and is ten times older than M35 (hence the orange stars). It contains many more stars than M35 but in roughly the same volume of space (30 ly wide), so looks more like a globular cluster. Nice contrast :)

M97 the Owl Nebula, is a planetary nebula in the constellation of Ursa Major, The Great Bear.

Estimated to be about 8,000 years old it lies just over 2,000 light years away from us. It's given the monicker 'Owl Nebula' because of what looks to be a round face with two big eyes.

M108, also in Ursa Major, is much further away at approximately 46 million light years. This barred spiral galaxy gets the nickname 'Surfboard galaxy'. This edge on galaxy is thought to have a black hole at it's core 24 million times the mass of our Sun.

Both objects were first discovered by the French astronomer Pierre François André Méchain in 1781. Discovering M108 three days after M97.
