** Thank you AstroBackyard.com** for all the videos

It'd been awhile since I'd been astrophotographing - felt great to be out under the stars and a smokeless sky. Fall is a excellent time for widefield astrophotography in the western US - there's a decent amount of astronomic dark, plenty of clear nights, temperatures aren't too cold, and quite a few interesting widefield subjects are available.

 

My goal with this small mosaic (only 2 panels) was to capture both the Fireworks Galaxy (NGC 6946, tiny here, bottom left) and the Elephant Trunk Nebula (IC 1396) in the same extent, with all of the interesting nebulosity in between, most notably the dark nebula Barnard 150 (AKA the Seahorse Nebula) in the lower left, one of my favs.

 

Surprisingly, I didn't detect much of the red emission Flying Bat Nebula (Sh2-129, center), part of which actually appears bluish (?, at first I was excited that I might have detected the Giant Squid Nebula (OU4), but nope, the blue is not in the right place). Previously I had captured Sh2-129, albeit faintly, with this same set up in the same location.

 

Part of the reason for this is that I stopped my Samyang 135mm down a half stop to f 2.4 (which I usually shoot wide open at f 2), not to tighten up stars, but to flatten out the heavy vignetting a tad. It did make a difference, but I did also notice that the Elephant Trunk Nebula didn't show up as strongly as expected based on my previous imaging of it. I'm still undecided whether I'll stay with f2 or move to f2.4, might depend on the subject.

 

There is a decent amount of what appears to be blue reflection nebulosity around star HD 198793 in the upper left quadrant; looking at widefield images of others, I can also see this faintly, but I haven't been able to find any closer images of it yet and it isn't cataloged in my astronomy app (SkySafari 6 Plus). It's possibly a processing artifact although it doesn't appear to be one.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

 

The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

The Dumbbell Nebula (Messier 27, M27 or NGC 6853) is a bright planetary nebula in the constellation Vulpecula. It is easily seen in binoculars and wide-field photographs. The central star is an extremely hot blueish subdwarf. The nebula was created by a dying star ejecting a shell of gas into space.

Helix Nebula

The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.[5] The estimated distance is about 215 parsecs (700 light-years). It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.[6] The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture,[7] as well as the "Eye of Sauron".[8][9]

NGC 4449, also known as Caldwell 21, is an irregular Magellanic type galaxy in the constellation Canes Venatici, being located about 13 million light-years away. It is part of the M94 Group or Canes Venatici I Group that is relatively close to the Local Group hosting our Milky Way galaxy. This galaxy is similar in nature to the Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC), though it is not as bright nor as large. NGC 4449 has a general bar shape, also characteristic of the LMC, with scattered young blue star clusters.

The IDAS NGS1 (Night Glow Suppression) Filter did a great job of blocking much of the white LED street lamp glow that surrounds my little house.

comments: color subexposures were way too long, resulting in a ridiculous amount of star halo and ccd bleed on the 3 largest stars. this took a lot of work in photoshop to undo, and it's still obvious that there was a big problem there. this was especially bad in the blue channel, hence the purple cast around the big stars.

After a lot of experimenting, I can say I'm finally happy with some of the results. And aside from all the technique, it took me quite a bit of patience to catch a long exposure with a truck on the road making colorful light trails in front of mountainous scenery without getting the shot ruined with oncoming headlights. Then up top, I got the stars including Rigel and a few constellations to appear as points of light. Best of all, it looks good large!

 

This image, coming from several exposures taken in sequence, was captured on Loveland Pass, near the Arapahoe Basin Ski Area and Keystone, Colorado. Oh and those glowing clouds at the top of the mountains... That glow comes all the way from Denver - some 50 miles away!

 

On the tech side, I used Deep Sky Stacker to reduce noise in the stars by combining 10 8 second exposures (ISO 3200, f/3.2). Then I used a homemade approach to extrapolate the settings needed for a long exposure of the foreground. It allowed me to test in 8 seconds and shoot something cool in 8 minutes (ISO 200, f/4)... sweet!! Oh yea, and I figured out how to (finally) use my live view in the dark for precision focus. On that I'll have to say when I first saw this mostly focused 8 minute exposure taken at ISO 200, I smiled really wide! So after combining the short frames in Deep Sky Stacker, I just blended the results with the foreground in PS.

Unfortunately the clouds rolled in after only 10x 20s subs. Would have liked an awful lot more to bring out the detail in M81. Reprocessed data using 20 flats, 20 bias and 10 darks.

Orion nebula photographed with 2.8/300 mm lens.

Yes, that works quite well!

0.8 sec exposure time, aperture 2.8, ISO 6400, approx. 5x digital magnification.

29 best photos out of 100 selected and calculated with DeepSkyStacker, with 15 darkframes (calculation of image noise) and 15 biasframes (calculation of transmission noise)

Without tracking!

Tripod low, no wind.

I took some time to collect some additional data on the galaxies Messier 81 and Messier 82 (M81 and M82) in the constellation Ursa Major on the evening of February 28, 2016. I used my wide-field setup which includes my Canon 6D and Canon 400mm lens mounted on an iOptron ZEQ25 mount. I collected 28-minutes of data using 60-second sub frames at ISO 3200. I also took the time to clip and process some of the background galaxies in my large 3 x 5 degree image, you can view them on my blog at: www.leisurelyscientist.com/?p=1592

Astrophotography is and has been my thing for a few years now. My main focus has always been the stars. Im happy to share the second of my two milky way shots in the Dolomites with you.

 

I reedited this one with Pixinsight which i have started to learn the basics of.

A picture of the open star cluster M67 in Cancer and variable star 60 Cancri (lower left) created by stacking 19 30 second images taken by a Canon 400mm f/5.6 telephoto lens on a Canon 7D MKII dslr camera processed using DeepSkyStacker, Gimp, and Lightroom.

Downloaded the trial version of PixInsight the other day (for the third time), and gave it a good going over, as much as I could. Finally came to the conclusion, rightly or wrongly, that there isn't a huge amount in PI that can't be done in PS, with one or two exceptions, one of which is DBE.

 

I used DBE on this as the gradient had caused problems in my previous iterations, then processed in PS. One other plus from PI was that, having studied a few tutorials, I learnt a bit more about noise reduction, and put that into practice.

 

This has to be my final version of this - I'm not going to get anything more out of it. I think it beats my previous one :) I saw a version of this the other day, probably better than this, that consisted of less than 3 hours of 5 minute subs - my skies got a verbal lashing that night, I can tell ya! :)
