IC 2118 (also known as Witch Head Nebula due to its shape) is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in the constellation of Orion. It lies in the Orion constellation, about 900 light-years from Earth.

Edited in Rawtherapee. It seems like the processing gets rid of all the EXIF data, is there a way to restore it?

Any constructive ccomments welcome.

In the constellation of Taurus the Bull resides The Seven Sisters. Or, the Pleiades star cluster. Also known as M45 in the Messier Catalog. The Japanese call it Subaru. The eponymous car company's logo is a stylized Seven Sisters.

This is a stack of eight 2-minute exposures. I bought Noel Carboni's Astronomy Actions pack tonight. This is the first image I tried it with. The bluish glow around the bigger stars is what is known as a reflection nebula. Or, more likely it is overflow of the photo sites on the camera sensor caused by the brightness of the larger stars. If it is to be interpreted as the reflection nebulae, then only the brighter portions of the nebulae can be seen through the light pollution from my backyard. There was also a thin layer of clouds so it was not completely transparent seeing.

The Pleiades, or seven sisters, (Messier object 45) are an open star cluster containing relatively young hot blue stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternate name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium that the stars are currently passing through.

Just like the horsehead, decided to go back and reimage this star cluster using longer exposures to see if I could get a bit more nebulosity out...looks like I did!

Stoked about how this one came out! The size of the nebula is perfect for the field of view of my telescope. It's super sharp with tons of detail despite the stock camera. Way more then my previous image of this object. Next month I'll have to get the western portion.

- www.kevin-palmer.com - On July 29th, Comet C/2014 E2 Jacques passed through a photogenic area of Auriga. In the field of view were star clusters and nebulas. The tail was very faint, although the coma was easy to find in a telescope. This is a stack of 8 2.5 minute exposures with a Takumar 135mm lens at f/4 and ISO 800. An iOptron Skytracker was used to track the stars.

This image is a composite of one shot for the foreground and for the sky over thirty exposures at ISO1600 and 55 second.

Well, it's not a new one! :)

And it is cloudy out there - I need something to do when it's dark. ;)

I've reprocessed this in an attempt to bring out a little more of the brown colour in the dust. Seems to have worked, although it's now starting to look a little "in ya face" again.

I may take this down tomorrow! :)

Very pleased with the core of this - you can almost make out the four stars of the trapezium.

- www.kevin-palmer.com - Comet C/2012 K1 PanSTARRS is still quite small and was around magnitude 8 when this was taken. But it was easy to spot in my 8" dobsonian telescope. This comet is moving closer to the sun each day and it won't be easy to see again until September. Hopefully by then it will be a little brighter. This is a stack of 11 2-minute, iso 1600 exposures with a Takumar 135mm f2.5 lens. An iOptron Skytracker was used to track the stars. This was taken at Sand Ridge State Forest, which has moderately dark skies.

Celestron CGEM 1100HD, Canon 5D3 using EF 70-200mm/f2.8L IS II set at 200mm (scope mounted)at ISO 400 and f2.8.

25 images were taken at 5 minutes per with dark frames for each. Images were stacked using DeepSkyStacker (which found over 65,000 stars in each image!) and then post-processed in GIMP. With 25 images that reduces noise by a factor of five (~2 stops or equivelent ISO of around 100 starting with 400). At 200 mm the area covered was considerably more than the Nebula so about 1/4th of the image was used. Even at that, the lens did a terrific job in capturing the detail. Additional noise reduction in the darker areas was achieved by converting the final image from RGB to YUV and then Gaussian filtering the U/V channels then converting back to RGB.

You can see why they call it "The North America Nebula" - top-center down to center looks like the North American Continent (gulf of mexico and all!). To it's right is the Pelican Nebula (IC 5070).

I used the telescope to do tracking while the scope-mounted camera and lens did the photographing. I had brought along my Canon 60A so I could take this without the IR filter of the 5D3 but forgot the adapter to connect the timer into the 60A (the two cameras use different plugs... thanks Canon!). The reason the IR filter is important is because the reds are H II regions and they emit close to IR frequencies (656 nm) - the 5D3 IR filter reduces them by a factor of 6! The 60A is specially designed to not reduce these reds (by much anyway).

Not very realistic, but I just love the colour.

Despite the title, this is my quadzillionth (and last) reprocess of this thing. The problem I have with this is bringing out what detail there is in the galaxy without completely bloating the stars, particularly those stars overlaying the galaxy itself - they have similar tonal values. This is about as good as it's going to get. Taken with a 200mm zoom lens and heavily cropped, I shouldn't be expecting miracles! :)

The Orion Nebula, M42

This is the result of stacking 47 30-sec long exposures taken with a Tamron SP 65B 400-mm prime lens with a 1.4x teleconverter at f/5.6 in front of a Nikon D7000 at ISO1600 riding piggyback on a polar-aligned 8" Celestron SCT. I used DeepSkyStacker to combine the images. The resulting 32-bit TIFF was then further edited with Photoshop and Topaz Adjust to enhance local contrast and colour.

Piggybacked my 314L and Sigma 70-300mm lens (set at 135mm) to the main scope to capture 10 subs at 5 minutes each of the Californian nebula in Perseus using an Ha filter. Stacked in Deepskystacker and processed in Nebulosity 4 and Photoshop.

Image taken 29/12/16

An untracked/unguided, short-exposure view of the planet Mars and the central portion of the constellation Leo the Lion which also includes the so-called M96 Group of galaxies (M105, M96, M95, NGC 3384, and others). I've identified with crosshairs the faint and small cores of these galaxies which are best seen in the Flickr light box or at full image size (press the "L" key to enter the Flickr light box and then click through to the "View all sizes" pane).

Stars down to and slightly below the 12th magnitude were recorded in this image as verified with the Cartes du Ciel star charting software (highly recommended free download). This image has been rotated slightly from the original capture to place north toward the top of the frame (approximately). To use as a finder chart for these galaxies note that this is a non-inverted, non-reversed image as would be seen with the naked eye or though a pair of binoculars.

Captured on December 7, 2011 between the hours of 4:20AM and 4:30AM PST from a significantly light-polluted, near-center-city location using a Nikon D5100 DSLR (ISO 4000, 5 seconds x 64 or just over five minutes total exposure integration time) and an AF Nikkor 35mm 1:2D lens set to aperture f/4. Image stack created with DeepSkyStacker (64 "light" frames and 32 "dark" frames) with final adjustments done in Photoshop CS3. Star diffraction spikes were enhanced in Photoshop CS3 using ProDigital Software's Astronomy Tools.

NGC 1333 & IC 348 and surrounding dust in Perseus as seen on 12/11/20. Captured under Bortle 4 skies using a Nikon D750 and Nikkor 300mm f/2.8 AI-S ED lens. 197 x 60" exposures at ISO 1600 and f/2.8. Processed using Rawtherapee, DeepSkyStacker, rnc-color-stretch, and Photoshop.

The North America and Pelican Nebulae are clouds of ionized hydrogen, and best estimates put the nebulae at about 1800 light years distant. The North America covers an area of more than four times the full moon (if you could see it!) but in fact is over 100 light years across.

First iteration - others may follow :). So many flippin' stars, my cheapo kit lens can't cope with them all :) And again, the red's a little clipped, but I can cope with that.

This is also the first time I've managed 90 second exposures, and my sky would probably allow a little more, which is nice to know.

This is the a portion of the Milky Way, a section of our home galaxy, that can be seen at the zenith in mid-summer around midnight. The diffuse whiteness are millions of stars in one of the spiral arms of our galaxy. The dark areas are clouds of interstellar dust and gas along the plane of the galaxy between spiral arms. It obscures a multitude of stars behind it.

First attempt at stacking with DeepSky Stacker and 10 images of Andromeda. I used 10 lights @ 60 sec exposures, along with 5 darks @ 60 sec exposures all at ISO 400. Brought final stacked image into Lightroom and made some adjustments...used some radial filters to help the galaxies out a little. So much to learn.

Here's a partially successful attempt at stacking intended to reduce the visibility of the the light cloud that persisted all evening. There's still too much haze for my liking, however the final product is better than any of the individual 15 light frames. I limited the shutter speed to 10 seconds to reduce the visibility of the clouds, although in hindsight it may have been better to go longer so that the Milky Way became visible. Messier 4 is easily seen to the right of Antares at the lower left of the image. Only the brightest stars of Messier 80 are visible; M80 roughly forms an isosceles triangle with Antares and Saturn, the latter at the upper left of the image. A surprise guest is the open star cluster NGC 5897, a barely visible tiny fuzzy patch to the right of Mars on the right side of the image.

The exposures were taken with a Canon 70D using the long exposure noise reduction features, which negated the need to take separate dark frames. The stack, compiled using DeepSkyStacker, includes 10 flat frames and 10 bias frames. The camera was mounted on an iOptron SkyTracker and the camera was fitted with a Sigma 50mm ART lens. All exposures were shot at f/1.4, ISO 800 in RAW format. Taken in Lake St. Peter Provincial Park, Ontario, July 23rd 2016.

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.

An unguided/untracked, short-exposure view of the Great Orion Nebula captured with a series of 1.3 second long exposures using a Nikon D5100 DSLR and a Nikkor 105mm AI-S telephoto lens.

This picture also recorded a series of tracks that may be from two geostationary satellites (these appear as blue, dotted lines to the left of the Orion Nebula, see the image notes for the precise location). The satellites appear as dotted lines because each one of the 33 images used to create this final stack of pictures was offset from one another to remove any movement in the stars caused by the earth's rotation. Thus, given this shift to align the star images any earth-stationary object will appear to move in steps between each exposure (thus the satellite images appear as dotted lines - one dot for each exposure).

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).

Captured on November 28, 2011 between the hours of 1:26AM and 1:28AM PST from a significantly light-polluted, near-center-city location using a Nikon D5100 DSLR (ISO 800, 1.3 seconds x 33 or 42.9 seconds total exposure integration time) and a Nikkor 105mm AI-S 1:2.5 lens set to aperture f/2.5 (wide open).
