Here, NGC 884 and 869 are shown. Commonly reffered to as "The Double Cluster", these two Open Star Clusters are reletively close to Earth within our Milky Way. The two lie in the constellation of Perseus. The Double Cluster is a naked eye object for some depending on age and location. Personally, NGC 884 and 869 are two of my favorite objects to look at. Because they are so large, most telescopes have to use low power magnification to veiw them, which makes the young hot stars really POP out from the background sky. Each star can be resolved, looking like a cloud of diamonds against the charcoal gray of the night sky.

Imaged with an AT65EDQ f/6.5 at 420mm of focal length.

The scope rode on a Celestron CG-5, guided with an Orion Starshoot Autoguider in an Orion 50mm mini guidescope, ran in PhD, and dithered with BackyardEOS.

The image is fully calibrated in DeepSkyStacker with darks, flats, bias, and flat darks. Post processing was done in CS6.

I decided to take advantage of the new moon, drag my telescope, and do some astrophotography last night...even with the time change and losing an hour of sleep. I'd say the bit of sleepiness today was worth it to get back into Astro and get this shot of my first time imaging this nebula!

The Rosette Nebula (NGC 2237) is 65 light-years across and 5,500 light-years away from Earth. It is visible in the sky between the constellations Gemini and Orion, in the head of the constellation Monoceros.

I polar aligned my mount using SharpCap Pro. My Sony a7SIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and the outputted TIFF file was brought into PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.

I wasn't thrilled about having the lodge in the photo. If I had planned ahead, I would have taken the shuttle bus up to the next stop to shoot the night sky, and walked back to the lodge (or taken the last shuttle).

I stacked six or so images in DeepSkyStacker, extracting two alignments (for foreground and sky). I also extracted and manually blended two exposures for the foreground.

The images were stacked using DeepSkyStacker and the final image was processed using LightRoom. Quite a lot of work was needed to adjust the background vignetting, as I didn't take any flat fields.

The clouds held just enough to get a few shots of the milky way under the beautiful dark skies of Bon Echo Provicial Park.

Here are my first few edits, feel free to comment on some improvements. I'm using Rawtherapee for all pictures, and will be using DeepSkyStacker to try and lower noise down in my next edits.

Thanks for viewing!

First Test of shooting the Milky Way with my new lens 50 mm f/1.8.

I was surprised by the brightness of the stars (I was able to see them even with the live view !).

I superimposed 30 photos of this part of the sky with DeepSkyStacker without taking any offsets or darks...

On it we can see clearly the red color of the nebulas NGC7000 and IC5070.

Sorry for the bad focus .

Thank all for your visit and awards.

This is a portion of the Milky Way running through Cygnus, The Swan. Deneb is the swan's tail and Sadr is the body. The wings go out in each direction and the neck extends out of the frame to the lower right.

The North American Nebula is clearly visible to the left of Deneb, and it got its name for obvious reasons. Just off the coast of "Florida", there's another, much fainter nebula called the Pelican Nebula. The nebulosity around Sadr is called IC1318... As far as I know, it doesn't have a nice, easy to remember name.

Taken with my "nifty fifty" lens, Canon's super-cheap-but-decent-quality 50mm prime lens. 15 exposures, each at 100 seconds (25 minutes total exposure time). ISO 1600 and F/4.0. Aligned and combined in DeepSkyStacker then tweaked a bit in photoshop.

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!!

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...
