Couldn't resist this :) I knew there was more there, and there is, but I may have pushed it a little too far. There's only the very faintest suggestion of nebulosity to the right (south) of the loop, and I can't bring it out. When the moon's gone, I'll give it another go. First iteration

 

Is this an improvement, or is this too "in ya face"? Despite appearances, it's just this side of being clipped.

On a whim I decided to go to the big annual Oregon Star Party, an amazing event for astro-nerds and fellow travelers that's held out in the boonies about a 4-1/2 hour drive from Portlland, and 1 1/2 hours east from Prineville in the Ochoco National Forest.

 

At the swap meet I bought a decent amature 8-inch telescope, but this photo was taken with my Canon T1i with the 18-55 lens zoomed to the widest view. The only trick was taking lots of 20-second exposures at ISO 3,200. This is the result of stacking 24 images with DeepSkyStacker. I didn't set out trying to get this kind of image, but rather trying to capture more meteors. No meteors showed up, but thanks to some tips from the astro-nerds I discovered photo stacking. It sure brings out the stars, the Milky Way, and the Andromeda Galaxy!!

I am finding post processing of astro images very hit and miss, and quite difficult, had another go at this one from the same stack file as previous, and tried very hard not to blow out the highlights, and this is the result, I think to an exstent astro post is very much to personal taste.

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. 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 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 2,000 times that 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.saved with settings embedded.

I have done this image of a part of the Milky Way by stacking 67 images of 8 seconds each at 3200 ISO with my Canon EOS 600D (unmodified) equipped with a basic 50 mm f/1.8 II lens.

 

I used also as it can be seen, no tracking mount. Just a simple tripod.

 

For french speaking people (or you can translate the thing) I have writen an How-capture-the-Milky-Way tutorial, available on my Blog : astrospace-page.blogspot.fr/2014/12/tutoriel-photographie...

 

This part of the milky way is really pleasant for me because it hides reams of nebulas !

A reprocess and uncropped version of another image of this pair I uploaded a few days ago. This one is the full field of view from my 80ED f/6.

 

Fireworks Galaxy NGC 6946 and Open Cluster NGC 6939

 

I've been experimenting with this image. It's a reprocess and uncropped version of the image I posted yesterday (bit.ly/2aZeH54). This time, I tried using the stacking in Photoshop instead of using my tried and true DeepSkyStacker.

 

What I find most interesting is that despite NOT using dark frames for noise reduction in this stack, the image actually turned out cleaner and with less noise than the version I stacked with DSS including dark frames. And I think the overall result is actually much nicer as a result of this.

 

That said, Photoshop lacks a lot of what I would consider critical features for doing this (like image quality estimation) and other tools, but in the case where I have a uniformly good data, the results were pretty astonishing.

Milky Way and Aurora.

5x20 sec stacked with DeepSkyStacker. 15mm, f/2.8, ISO3200.

Clear sky here last night so I took my camera to the outskirts of our city and pointed it in the direction of Orion for some shots. DeepSkyStacker used to stack 11 frames (f5.6 10 sec exposures at ISO 4000!)

Object Details: Having been in the midst of thunderstorms for the past several days, not to mention the nearly full moon at the moment; the peak of this year's Perseid meteor shower has been a bit of a non-event in this area.

 

Therefore, I made the time to take a first look at some wide-field Milky Way images I took while attending my 31st annual Stellafane astronomy convention (held during the first weekend of August in Springfield, Vt, USA (it's 84th year)).

 

Although I concentrated mainly on visual observing this year, and had the pleasure of viewing dozens of objects through some excellent large binocs & 20" class dobs that my friends had brought, I did setup a Star Adventurer tracking mount & Canon 700D (t5i) with an 18-55mm 'kit' lens and used APT and a laptop to take a series of automated exposures.

 

Upon examining the resulting images I found that Mother Nature had brought me a small present the morning of my birthday by allowing me to capture one frame showing two meteors running nearly parallel along the portion of the Milky Way known as the Summer Triangle!

 

Image Details: Taken from the scope field at Stellafane 2019 by Jay Edwards on the morning of August 2nd using a Canon 700D (t5i) and standard 18-55mm 'kit' lens riding on a Star Adventurer tracking mount, the attached is a single 2 minute exposure at ISO 1600 with the lens set to a focal length of 21mm and an aperture of f/4.

 

As presented here, it has been calibrated with darks & bias frames (but not flats), was processed in a combination of DSS, PI & PSP, is shown uncropped, has been re-sized down to 2X HD resolution and the bit depth lowered to 8 bits per channel.

 

Although the meteors will most likely get lost (averaged out) in the process, I'm hoping to have captured some additional images of this region of a sufficient quality in order to process a stacked image in an effort to improve the Milky Way's signal-to-noise ratio.

Taken through a borrowed Sigma 70-200 f/2.8, lightly cropped. Two 2-minute exposures stacked in DeepSkyStacker. If I had more time with the lens, I'd liked to have done an HDR set (so as not to burn out M42), but alas, condensation on the glass cut my imaging time short. I also didn't get a flat frame, which made processing difficult... once I brought out the Horsehead, the center of the picture was a bright orange blob. I tried synthesizing a flat in IRIS with no luck, and eventually just used a flat frame I took with one of my own lenses, which almost matches.

I usually crop my images down more than this but, there is a few clusters towards the edges and to the far right is IC 417. I may reprocess it at a later date and crop it right down to the fly nebula.

 

The Fly nebula lies in the constellation of Auriga. It is an emission nebula and a reflection nebula. Sometimes referred to as a mini version of the Orion nebula, as it has a star cluster, including it's own version of the Trapezium. Some estimates have the nebula at about 7,000 light years from us.

FINALLY got this image processed. Started gathering data for this project in early November 2020 but the weather has been so bad here in the UK, that I have given up trying to add further data to this image this. Only 6.6 hours total integration time sadly.

Quite happy with how it turned out though as I am still getting back into the hobby and learning all I can about post-processing. The dark arts are deep and mysterious in this hobby.

Description:

 

This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.

 

From Wikipedia:

 

"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

This is my first attempt at photographing the

milky way. It's difficult as there are few clear

sky nights and I live in very light area. It's much

darker here in Seaton and there's a nice open

view over the sea.

 

It is 25 photos, lights, darks and bias, stacked

with DeepSkyStacker 5.1.3. Rather than using

the raw files, I used JPEGs to cope with barrel

distortion. Saved result to clipboard and then

used paint to create a JPEG. Squared, framed

and colour balance changed using my software.

Now the Moon has taken it's leave for a while, and Orion is showing himself at a reasonable hour, this is the next obvious target.

Explanation: The first hint of what will become of our Sun was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae on the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27, shown here in colors emitted by hydrogen and oxygen. Understanding the physics and significance of M27 was well beyond 18th century science. Even today, many things remain mysterious about bipolar planetary nebula like M27, including the physical mechanism that expels a low-mass star's gaseous outer-envelope, leaving an X-ray hot white dwarf.

An attempt at capturing some of the Milky Way through some pretty bad light pollution. 24 light frames, 25 seconds each and some 20 darks. Stacked in DeepSkyStacker and edited more in Photoshop. Processing it all was... interesting, which I think shows in the image. It may look a bit too blotty and blown out in places for my liking but I'm done tweaking it for now!
