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.

To the naked eye - the light of the Milky Way is completely drowned out by the horrible light pollution in San Antonio.

This is my first barely-halfway-decent attempt at capturing what little light manages to break through.

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.

17 images, 30 secs each , f/4 , iso 800, deepskystacker

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).

The Heart (IC 1805) and Soul (IC 1848) Nebulae are emission nebulae i.e. clouds of ionized gas, that lie about 6500 light years away in the constellation Cassiopeia. Between them is the star cluster NGC 1027.

Not brilliant framing, but, as you know, it's difficult when you're pointing your camera at nothing - next time I'll try this at 175mm. Still, half a soul is better than being completely soulless. :) The Soul looks more like a pork chop to me, but I guess Pork Chop Nebula doesn't have the same ring ;)

Note: greed is bad. Instead of shooting Pleiades and rising Orion I should have concentrated on this target. And now I have three bad datasets instead of one mediocre :(

I finally managed to get some good data from my light polluted backyard. We have a long weekend starting tonight and clear skies every night. The moon rises late and it won't be too cold just after the end of twilight. So, here's a 30 minute (10 x 3 minute exposures + darks) stack of the Great Orion Nebula (M42), the Running Man Nebula, the Fire Nebula, and the Horsehead Nebula. This is a first go at the post-processing. I'm going to try a few other techniques later.

Thought I'd apply the new technique to this one, which is a bit tricky due to the number of stars (I haven't counted them, but there's a lot!). Good practice though - took several iterations before I came up with something that I think is an improvement on the last one. The fainter areas of the Heart are now just visible and the stars are more controlled.

Moon's back and I've run out of things to reprocess. Not sure what I'm going to do now :(

The famous Double Cluster (a.k.a. h and Chi) in the constellation Perseus, with an alternative route of post-processing to digitally reduce chromatic aberation. Imaged with TAIR-3S @ f/5.6 on Samsung NX30 with Rollei Astroclear (anti-citylight) filter. 23 subs of 30 s exposure. ISO 3200.

Stacking with DeepSkyStacker. This time, I first used Adobe Photoshop to multiply the somewhat defocused Red channel with the sharp and crisp Green channel to remove some of the chromatic aberration. For the Blue channel, the defocus due to chromatic aberration was substantially less than for Red. Further post-processing was done with Aurora HDR 2018 (tonemapping, color corrections, HDR cosmetics) and ImageJ (2x2 binning). I would be glad to hear your opinion which version you like better!

The constellation Cygnus, the North America Nebula, the Milky Way, and the tops of my neighbor's ponderosa pine trees.

This is 2 images combined by DeepSkyStacker, and postprocessed in Gimp to accentuate the region around the NAN at the expense of the rest of the image. This is my first image with DSS, and I am very encouraged by the result. You can even faintly see the Pelican Nebula next to the NAN.

The stars were tracked with my hand-operated barn door tracker, and the exposure was somewhere between 15 seconds and 2 minutes. I was using a hand tape recorder to note the exposure data, but alas nothing is on the tape. I'm guessing 1 minute.
