Except for the rings of Saturn, the Ring Nebula (M57) is probably the most famous celestial band. Its classic appearance is understood to be due to our own perspective, though.In this well-studied example of a planetary nebula, the glowing material does not come from planets. Instead, the gaseous shroud represents outer layers expelled from the dying, once sun-like star, now a tiny pinprick of light seen at the nebula's center. Intense ultraviolet light from the hot central star ionizes atoms in the gas. In the picture, the blue color in the center is ionized helium, the cyan color of the inner ring is the glow of hydrogen and oxygen, and the reddish color of the outer ring is from nitrogen and sulfur. The Ring Nebula is about one light-year across and 2,000 light-years away.

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!!

Using new techniques i've recently learned on cancelling out light polution in Photoshop, I decided to put it to the test and have re-processed this image taken last year of the Orion Nebula. It takes a little time to do but the results are well worth it compared to my earlier attempt seen here.

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 !

 

We can find on this picture :

 

- North America Nebula (NGC 7000)

- Pelican Nebula (IC 5070)

- Butterfly Nebula (IC 1318)

- Veil Nebula (NGC 6992 and NGC 6960)

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.

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!)

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.

Source of explanation: NASA APOD

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.

After seeing these excellent photos right next to each other in my contact photo list, and seeing a clear night sky for the first time in 2008, I thought I'd snag an Orion Nebula shot of my own. That's the Running Man nebula near the top.

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.

I wasn't going to process this because I had triple spikes around Alnitak following the addition of data from previous sessions and not realising that the camera wasn't aligned in the same way each time! Doh! So I cloned them out.

 

This looks more natural than my previous overprocessed/clinical efforts, although it needs shed loads more data of course, which I can't provide unguided. 1 hour 26 minutes in total.

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.
