M42 - THE GREAT ORION NEBULA AND RUNNING MAN - Jan 2021
Ok, this is my final version of this subject for this year. I added another 2 and a half hours of data, to make this a total final exposure of 5 hours.
This is an HDR image created by blending 3 different exposure lengths after stacking and initial processing in Photoshop. It is the first time I've really tried to complete a full HDR image and I think the core of M42 has turned out OK. You can still see detail in the bright Trapezium core region, as well as still seeing fainter details in the outer nebulosity.
I am super happy with the look of this final image, it's muted and has a slightly dreamy colour balance, some will say I've pushed the data too far, but I like it.
Thanks for looking and sharing, comments always welcomed.
Clear skies.

This, I am reliably informed by my software, is the cluster M34 aka NGC 1039, chillin' up there somewhere in Perseus. With some spikes of course, to make it a little less uninteresting. Charles Messier must have had bloody good eyesight!

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth. M57 is the glowing remains of a sun-like star. The star expelled a vast envelope of ionized gas before becoming a white dwarf.

Night shift today with my son Kevin. The green dot on the top right is the comet "Leonard". It passes the earth only every 80,000 years (!) and is visible this year from late November to early December. Unfortunately the weather is very cloudy, we have been watching the weather forecast for days and saw last night that this morning could be an opportunity with a lot of luck. So we got up at half past four and searched. After about 30 minutes we had found it. Then made a total of 120 pictures each 4 seconds and stacked them with DeepSkyStacker. Lens was the "bokeh master" Sigma 105/1.4.

Ho usato solo lo spianatore con il 102 a 700mm, sono molto contento del campo ai bordi :) ma si sono generati due strani flare che erano già comparsi con la foto delle Pleiadi di settembre, chiaramente non ho la benchè minima idea di cosa la generi, forse il filtro skyglow, nelle due foto ho usato due spianatori differenti..

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms. (ref: Wikipedia and NASA)

A spiral galaxy in the constellation Camelopardalis.
It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.

I think I stopped the aperture down a bit too much on this one, causing the diffraction spikes around the Pleiades's brightest stars. Next time, I'll try f/5.6 or f/6.3.

More commonly known as The Dumbell Nebula. Sometimes as the Apple core or egg timer as well.
M27 is a planetary nebula over 1,200 light years away in the constellation of Vulpecula. Discovered by Charles Messier in 1764 it's thought to be the first planetary nebula discovered.
They were given the title planetary nebulae by William Herschel, who thought that these kind of objects looked small and round like a planet.

While I'm waiting for a new 12mm f2.0 lens, I thought I'd test my new Fuji X-M1 with the kit zoom under the light polluted skies of suburban Melbourne at ISO 6400. Then I pushed and played as much as I dared.
It's not realistic, but it is remarkable what a digital camera and software can do these days.
A photo of our galaxy, the Milky Way, taken just outside our chalet at Crystal Springs Mountain Lodge in Mpumalanga, South Africa. It's amazing what a dark, clear sky can show (along with a little work on the computer). This is 10 photos that I took (each 30 seconds exposure time), stacked together (using Deep Sky Stacker), and then edited a bit in GIMP. My first real Milky Way shot!
If anyone is curious about how I went about getting this shot, I wrote a "how-to" here: digital-photography-school.com/forum/how-i-took/197256-mi...
there the stars are born from the Cocoons.
Covering the large portion of the Milky Way, which is the disk subsystem of our Galaxy, constellation Cygnus houses a lot of gaseous and dusty entities, both bright and dark. This image features among others the tiny bright Cocoon nebula (IC 5146/ Caldwell 19) which is a star formation region and much more prominent dark filament of Barnard 128 (the Snake nebula).

Av = f/2.8
ISO 4000
Exposures: 58 (plus 27 dark frames and 10 offset frames plus 2 fake flat-field frames).
Processing: Contrast was set to "linear" for all images in Canon DPP and 16-bit outputs were fed to DSS and stacked in Maximum Enthropy mode.
16-bit stacking result was processed in Photoshop with AutoContrast and Levels (namely gamma was set to 3,5) and Curves (skewed sigmoid curve was applied).
Note: I had to crop away some portion at the bottom of the image. The stars were really ugly there.
Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.
It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 30 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker (used comet stacking mode so stars and comet were stacked separately and then combined), editing with Astro Pixel Processor and GIMP, taken in the 30 minute-window between astronomic dusk and the rise of the 93% illuminated moon on April 9, 2020 under Bortle 3/4 skies.
'Ave anuvver one :)
Did this the same session as The Ring Nebula. Two images in one session - whatever next? :)
M103 aka NGC 581 is one of the most distant open clusters known, with distances of 8,000 to 9,500 light years from Earth and ranging about 15 light years apart. The cluster is about 25 million years old. Thus spake Wiki.
To me, it's number 27 :)
Taken with a TMB92L, Canon T3i DSLR, and Celestron CG-4 mount. Consists of 34 light and 20 dark frames, each a 45-second exposure at ISO 800, stacked in DeepSkyStacker and processed in Photoshop.
First light with my first ever dedicated astronomy camera. It was a trial and error evening. After a lot of hair pulling and youtube watching, I managed to get most of the equipment talking to each other. So I decided to try it out on an easy target, Messier 82 the Cigar galaxy. I won't bore you with M82 facts . . . this time. If you do want to know, I did post a picture of M82 not long ago taken with my DSLR. If you flick back through some of my recent pictures you'll find some M82 facts there.
And now for the really boring bit, equipment used:
Skywatcher Quattro 8" Newtonian Reflector steel tube with the f4 aplanatic coma corrector, Skywatcher EQ6 R pro mount, Altair Starwave 50mm guide scope, ZWO asi120mm guide camera mini, ZWO asi533mc pro cooled to -10c, ZWO asiair plus.
20, 3 minute exposures bin 1 gain 0, stacked with darks, flats and bias.
DeepSkyStacker, StarTools and Affinity Photo used for processing.
