The owls on the hillside just north of my home have been keeping me company at night. This little star cluster has risen above the treeline from which they call.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

 

It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements.

This is my first real attempt at image stacking. This actually took quite a while, now I just need to learn how to spot things in the sky. Ultimately, my goal is to get a nebula, i know now, this is going to take some work.

 

The process is quite involved, the image processing is involved as well and with it comes all kinds of algorithms and processes..

 

So, just learn as you go.

Nice, bright star cluster in constellation Cancer. This cluster have fallen into the sweet spot of my optics, so the halos around bright stars are at least center-symmetrical and not comet-shaped. Yes! This one turns out at steady 3 out of possible 5.

 

This shot and this share the same effective resolution so the apparent sizes can be compared. This only applies to "original" size of the images. M67 is tiny compared to Praesepe/Beehive. And has only 7,5m against 4m of the Beehive.

 

Aquisition time: 13.04.2013 ‏‎around 23:45:00 MSK (GMT+4).

Equipment:

Canon EF 70-200 f/2.8L lens + Canon EF 2x III extender on EOS 60D mounted on Celestron CG-4 GEM (German equatorial mount) with RA drive.

Aperture 71 mm

Focal length 400 mm

Tv = 30 seconds

Exposures: 85 + 12 dark frames

Processing: contrast was set to "linear" and vingetting was corrected with Canon DPP, 16 bit TIFFs were stacked in DeepSkyStacker, contrast'n'colors adjusted in Photoshop. Image scaled down 50% (cheat!).

Notes: this time I have recorded the steps of contrast adjustment. I'll better have bluish sky than reddish.

Orion Nebula, the middle "star" in Orion's sword. Crop from this image. 105 stacked 1/2 s exposures from Olympus E-520 with 300 mm lens.

We had three relatively clear nights on the bounce last week, which hasn't happened since the Roman occupation ;) This was taken Saturday night, but I only managed 12 frames before some cloud rolled in, so this is just 36 minutes.

 

Taken with the longest lens I possess at present (200mm), and then cropped a bit to take out the remnants of the amp glow that my darks don't seem to want to deal with at the moment, it doesn't reveal a lot of detail. But it looks cute! ;)

A wide-field shot of the Ring Nebula (M57) in the constellation Lyra taken with a Nikon D5100 DSLR using a lens of only 100mm focal length. This image is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).

 

This is a stack of eleven images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). The faintest stars recorded in this photo range down to approximately magnitude 13.5 (see image notes which identify a few of the brighter stars, north is off to the right).

 

Captured on October 17, 2011 between 8:03PM and 8:23PM PDT under fairly bright, hazy, light-polluted skies with a Nikon D5100 DSLR (ISO 3200, 25 second exposure x 11) and a 70mm-300mm AF-S G Zoom Nikkor lens at its 100mm f/5.6 position. Image stack created with DeepSkyStacker using eleven image frames combined with eight dark frames (no flats or bias).

Just faffing about using my new found "skills" whilst waiting for the sky to clear (and the moon to reappear!) :) An improvement on the last iteration I think, and much easier to process, although of course still sadly lacking in detail - I can't pull signal out of the hat ;)

The Orion Nebula and De Mairan's Nebula, M42 and M43 respectively, as viewed under urban light using an Astronomik CLS Clip-Filter. The CLS (City Light Suppression) is an interference filter that blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter. This was my first attempt at using the filter and stacking images using DeepSkyStacker. Camera used was a Canon EOS 70D, with an EF 24-105 mm lens, mounted on an iOptron SkyTracker. Location was Burlington, Ontario, 43°19'57" N, 79°46'38"W, ambient temperature a balmy -13°C under a waxing gibbous moon, no cloud cover and marginal to average transparency and seeing. Eight light frames and six dark frames, no flat or bias frames, all shot at ISO 400, f/4 for 30 seconds and 105 mm.
