Adding Color 📚 (Whirlpool Galaxy)

I've got a ways to go before I am happy with my LRGB process. It was REALLY satisfying to add color to the luminance data on this gorgeous galaxy.

Some seriously noisy areas - I went a little crazy with saturation without masking and just generally careless and wild in the processing.

Only about an hour in each color filter, but I couldn't resist bringing it all together.

Thanks for looking guys, clear skies!

Amazing how much detail there is in the RAW data, but its extremely tricky to tease it out.

This is around an hours worth of exposure, taken on the amazing Samyang 135mm f2, and a Nikon D500, and tracked on a MoveShootMove tracker.

I photographed this handsome nebula about 2 weeks ago during a nearly full moon with the Optolong L-eXtreme filter.

NGC 7380 is a "must-shoot" object in Cepheus in my books. It's a fantastic target to try with a one-shot-color camera or DSLR, but a light pollution filter with narrow bandpasses will help keep those stars from taking over.

This embarrassment has been reprocessed here!

First iteration. I'll fill in the details later :) (Pelican must be on holiday!)

LATER:

OK. The Deneb and Sadr region of the Constellation Cygnus, right smack bang in the Milky Way (hence all the stars). I got the North America Nebula, NGC 7000, which I was pleased with, but the Pelican Nebula is sadly missing (although astrometry seems to be able to see it!). This obviously needs more time. I had to stop at about 40 subs as half a moon had risen and the clouds rolled in. So, after ditching a few subs - but not, I'm happy to say, through tracking errors - this is 35 x 80 secs for about 47 minutes. At 55mm, I had no tracking errors at all at 80 seconds, but I'm getting very near the sky limit here, so 90 is probably going to be my max. Hey ho, we have to work with the tools we have! :)

NGC2244 and the Rosette nebula in narrow band

I've done too many different colour schemes and palettes for this data now, so i'm going back to basics for this one - h-alpha=red oiii=blue, and oiii=green. bi-colour with a red-ish tone.

might upload a different one some other time.

Only about 1.5 hrs in 5 and 10 minute exposures.

Although not really considered part of the 'spring galaxies' retinue this is an excellent time of year to image or observe this wonderful, contrasting, pair of galaxies as they are at zenith for us mid-northern latitude observers.

This is really a rescued image as the ccd camera misted over several frames into the run. It forced me to try new software to stack with as DeepSkyStacker did a very poor job (with admittedly poor data).

So this is my first attempt with Astro Pixel Processor and although I am a huge way from understanding it, it did produce a workable image for me despite endlessly telling me the image would not be properly calibrated.

okay. i think i've done as much as i'm going to be able to do with the subs that i've got here.

all data acquired with LB-0003 in rodeo, nm, between 11/15/2009 and 11/18/2009. LB-0003 is a 12", f/9 R-C astrograph attached to an Apogee Alta U16M CCD camera. FOV is 45 by 45 arcminutes.

L(RGB); L=180s,240s and 480s @ 1x1 bin. histogram stretch in pixinsight LE, followed by 'hdr' fusion with enfuse. resultant tiff then processed with curves and a trous wavelet functions in pixinsight LE.

RGB = 180s and 240s each channel @ 2x2 bin. 2 separate stretches+curves prepared from 240s data and one prepared from the 180s data using pixinsight LE. these 3 frames hdr merged with enfuse, then upsized to 4098x4098 and slight noise reduction in pixinsight LE.

LRGB stack in photoshop CS, then final tweaks in lightroom 2.

all frames registered and aligned with deepskystacker.

all of this and the trapezium is still blown and grey... ugh.

Such a cool galaxy, and SMALL!

I photographed this one last week using the Sky-Watcher Esprit 150 (1050mm focal length) on the EQ8.

A few more lessons learned on this one, the big one being optimizing exposure times depending on target/filter.

I shot 7-minute LUM exposures - which were not ideal. Next time around I'll shoot shorter subs and try to rack up a lot more.

A mere 25 million light years away (as the crow flies) i.e. this is what it looked like 25 million years ago.

We've had two clear nights on the trot this week, which must be a record for the UK. Beset with problems the first night (not least of which I couldn't find the thing!), so managed just 18 90 sec subs. Second night managed 88 subs of 30 seconds remotely. So this is just over the hour after DSS had ditched some.

First iteration - watch this space! :)

Reprocessed here

I first shot Comet C/2020 F8 (SWAN), which was just barely above the horizon. I abandoned that idea after one shot - the core was just barely visible, and I was almost sure I wouldn't get much of the tail because I was shooting so low. Plus there were quite a few low clouds along the horizon, despite most of the sky being perfectly clear.

After being disappointed, I was about to pack up and get some sleep, but decided I'd get just one shot of Comet C/2017 T2 (PANSTARRS) near M 81 and M 82. I almost packed up again when I had trouble locating M 81 and M 82 quickly, but finally found them after searching (no go-to capabilities with the SkyTracker of course).

Instead of being disappointed this time, I was surprised and excited to see an obvious tail on Comet C/2017 T2 (PANSTARRS) in my first shot, so I stuck around and got some more subs so I'd be able to pull out the Integrated Flux Nebulae (IFN) in the area.

I wish now I'd just stuck around for just another 20 minutes of so but whatever, I'm happy with this image and its layers: it features a comet within our solar system (14 light minutes away), IFN near the edge of our galaxy, and distant galaxies (Bode's Nebulae are about 12 million light years away).

Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 43 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken May 23, 2020 from Bortle 3/4 skies. I didn't bother to stack on the comet and stars separately - so the core of the comet is slightly smudged, but that gets lost in the bright core of the comet after stretching to bring out the IFN.

This was one of the most exciting projects for me to work on. Still new to monochrome imaging with a CCD camera, and building SHO palette images.

Plenty "wrong" with this image, mainly the mix of colors (I guess it's a Hubble Palette hybrid?). Probably too heavy on the green for most, but I'm really digging this look.

Thanks for looking, and happy shooting!!

A stack of 6 exposures of 5 minutes each making a half hour of integration time. I stacked this with DeepSkyStacker and accidentally left the 2x drizzle on so that's why it's such a large image.

1st time out with my Askar FRA400 telescope.

Wouldn't quite fit the entire galaxy in to the field of view, so I went for a 2 panel mosaic.

M31 lies 2.5 million light years away from us and has two visible dwarf galaxies for companions. They are M32, just above and left of centre and M110, an elliptical galaxy to the bottom centre of the image.

I've been waiting over 2 months for a clear, Moonless night for deep sky imaging. Even by UK standards, it's been a frustrating Summer! Once the appropriate conditions finally came, they didn't last long and I only managed 3 frames.

This is part of the famous Veil Nebula supernova remnant. The bright star with the reflection halo is 52 Cygni.

Despite the limited frames, I think the result is slightly better than last year's of the same subject, as I've stopped the telescope's mirror shifting - by fitting stronger collimation support springs.

Use F11 and L for best view.

This beautiful galaxy resides in Coma Berenices, and I highly recommend this target for my fellow northern hemisphere imagers!

This image uses 4 hours of total exposure time captured from a bright city sky.

I collected exactly an hour's worth of data (20 x 3-minutes) through each LRGB filter (not nearly enough!) and stacked each set together in DeepSkyStacker using dark calibration frames).

The color channels were aligned and processed entirely in Adobe Photoshop to complete the image. Thanks for looking, and clear skies!

The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is in the constellation Virgo. From my vantage point, it just makes it high enough over the roof of my house to capture some photons a few nights a year. The Sombrero Galaxy is about 31,000,000 light years away with an apparent magnitude of 8.3.

The Rho Ophiuchi and the Antares region are incredible glimpses of the night sky. They are full of multicolor reflection and dark nebulae.

Blue, orange, cyan and red nebulae decorate one of the most beautiful constellation of the boreal sky: the Scorpius (one of my favourites).

In this photo on the left you can see the cyan/blue Rho Ophiuchi nebula near a scythe-like dark nebula on the right. Two of the three stars inside the Rho Ophiuchi nebula are actually double stars.

Antares is on the right, just a little bit over the frame (south). That's why everything looks golden in that area (Antares is a red giant).

Unfortunately the sky was not perfectly clear that day so the photo is not like I imagined it.
