Astrophotography by Noel Carboni

The Moon in Hypersaturated Color Stacked from 15 exposures of 1/5 second at ISO 100 This image is a mosaic of 15 separate and slightly overlapping 8.2 megapixel images from my Canon EOS-20D (unmodified), taken in Raw mode and converted and stitched together in Photoshop CS2. The exposures were each 1/5 second at ISO 100. I mounted my 20D to my Meade LX200 GPS UHTC 10" Schmidt-Cassegrain telescope via my 2x Televue Powermate (a focal length doubler, similar to a teleconverter, which also serves to mate my camera to the 2" telescope eyepiece tube). Effective focal length was 5000mm f/20. Looking through the viewfinder I swept across the surface in a zig-zag fashion, trying for about 1/3 overlap between frames. I triggered the shutter with my TC80-N3 remote timer/controller. I did the stitching by hand in Photoshop. Since it was taken at the camera's most noise-free setting (ISO 100), the data is very accurate, and thus I was able to strongly increase the saturation via Photoshop's Image - Adjust - Hue/Saturation function.

Polaris - the north star. Stacked from 16 exposures of 30 seconds at ISO 200 plus 14 exposures of 30 seconds at 1600 with 0.63x focal length reducer / field flattener and IDAS light pollution filter on my LX200 telescope. Shot in Raw mode and converted in Adobe Photoshop using -20% color saturation so as not to clip the black point. Click here to see a medium resolution image.

M13 - Globular Cluster. Stacked from 30 exposures of 30 seconds at ISO 1600 at prime focus of my LX200 telescope. M13, also called the Great Globular Cluster in Hercules, is one of the best known globulars of the Northern hemisphere. This image isn't deep enough to show nearly all of the several hundred thousand stars in M13. Click here to see a medium resolution image. Click here to see a high resolution image.

M43 Nebula. Stacked from 132 exposures of 20 seconds at ISO 1600 at prime focus of my LX200 telescope. M43 is the roundish nebula with the star in the center. Part of the M42, the Great Orion Nebula, also shows at the lower-right of the image. Click here to see a medium resolution image. Click here to see a high resolution image.

M104 - The Sombrero Galaxy. Stacked from 30 exposures of 30 seconds at ISO 1600, some at prime focus and some using my 0.63x focal length reducer. Photographed at my dark site near Lake Okeechobee in Florida. Click here to see a medium resolution image. Click here to see a high resolution image.

The Coma Bernices star cluster. Wide starfield shot stacked from 7 exposures of 2 minutes at ISO 3200, using my 100-400 zoom lens at 200mm piggybacked atop my LX200 telescope.

The Big Dipper asterism, part of the Ursa Major ("Great Bear") constellation in the northern sky. I shot this image by mounting my camera with 17-40 zoom lens at 31mm atop my telescope and using the mount to track the stars. As long as I keep the exposures fairly short, circular trailing is kept to a minimum even though I'm using the telescope in altitude-azimuth configuration for ease of setup. If you look carefully in the high resolution image, there are quite a few tiny deep sky objects (galaxies and nebulae) visible. APOD (Astronomy Picture of the Day), March 17, 2006.

Messier Objects 82 and 81 Wide Field. I shot this image by mounting my 20D with Canon 100-400 zoom lens at 300mm piggybacked on top of my telescope. If you look carefully in the high resolution image, there are a few galaxies besides M82 and M81 visible. Click here to see a medium resolution image. Click here to see a high resolution image.

A high magnification image of the planet Saturn and five of its satellites. The upper atmosphere was moving around early on, but by about 10 PM it had really settled down. It was great looking at the moon and planets with super-high magnification through still air. About the time Saturn's Encke division showed in the eyepiece I figured I'd better break out the LPI and do some imaging. The optics in my LX200 continue to amaze me. There's some odd 3 point flaring when the scope is warm, but man when it cools down (to 65 degrees F in the case of last night) there just don't seem to be any limits! I was quite comfortable looking at Saturn with my 2x Powermate and 9mm Nagler... What's that, 556x? Amazing! Right at diffraction limits. Click here to see a medium resolution image.

NGC 2392, the "Eskimo Nebula" or sometimes known as the "Clown Nebula", a "planetary" type nebula so named because it is round and about the size of a planet. It's really the outer shell of a star not unlike our sun that's been blown off at the end of the star's life. Not long ago I decided I'd try to concentrate on photographing small, bright objects, insofar as I have a lot of light pollution here at my home, and I have a long focal length scope (10" LX200 GPS UHTC, 2500mm f/10) with great tracking. Thus, the "Eskimo Nebula" seemed a good fit. I did some exposures of this object about a year prior, before I had a Powermate and knew much about processing. I decided I needed to do it better. This is stacked from 60 Canon 20D JPEG images at 15 seconds, ISO 1600 plus 55 Raw images at 20 seconds, ISO 3200 through my 2x Powermate, which made the telescope 5000mm f/20. Note that this is unguided in alt-az configuration. I took one dark frame to calibrate all images, and it greatly reduced hot pixels in both sets of shots.

M45 - The Pleiades, Wide Field. My second attempt at this cluster with my 20D and 100-400 zoom lens piggybacked on my telescope, this time from a site with darker skies. I was able to sustain 2 minute exposures at ISO 3200. The only thing keeping me from going deeper and getting a cleaner shot was that clouds moved in before I had finished the exposure set.

M31 - The Andromeda Galaxy Most folks don't realize how large the Andromeda Galaxy is. It requires a wide-field setup - in my case a camera lens on my dSLR, piggybacked on my telescope to track the stars. Visible also in this shot are M32 (the small blob left and a bit up from the main galaxy's center), and M110 (the blob to the lower-right). Canon EOS 20D at ISO 1600 through Canon 100-400 zoom lens @ 300mm, f/5.6. 92 x 30 second subs stacked in Images Plus, and processed in Photoshop Click here to see a medium resolution image.

The Sword of Orion I piggybacked my Canon 20D and 100-400 zoom lens on top of my LX200 and got this wide field shot. This is NGC1977 (the Running Man nebula), M43 (the little mostly round nebula), and M42 (the Great Orion Nebula), all making up the sword of Orion. Canon EOS 20D at ISO 1600 through Canon 100-400 zoom lens @ 300mm, f/5.6. 22 x 30 second subs stacked in Images Plus, and processed in Photoshop Click here to see a medium resolution image.

Saturn 161 of the best frames of Saturn chosen by Meade Autostar software, taken with Meade LPI (Lunar/Planetary Imager) through Powermate 2x on Meade 10" LX200 GPS UHTC, stacked in Registax, upsampled in Photoshop, Adaptive Richardson-Lucy sharpening in Images Plus, color balance in Photoshop, final sharpening with my dSLR Fractal Sharpen actions. Moments of reasonably good seeing that night. Click here to see a medium resolution image.

M45 - The Pleiades Piggyback my 100-400 lens on my LX200 - check! Tighten zoom ring so no slippage - check! Find best focus (not at infinity mark) - check! Determine max exposure time at 300mm f/5.6 - 30 sec ISO 1600, limited by LP. Took a bunch of exposures for half an hour before the battery died. The LX200 unguided alt-az tracking was great, at 300mm I was able to use EVERY SINGLE exposure in the stack; all had pinpoint stars and no trace of rotation. Woohoo! Problem is I could *BARELY* coax any nebulosity out of the resultant image. I got more out of two exposures during the power outage after the hurricane. I really need to get to a dark sky site for this one. Click here to see a medium resolution image. Click here to see a high resolution image.

Mars When I got my LX200 almost a year ago, included in the package was the Meade Lunar Planetary Imager (LPI). I tried it out exactly once, but because I was having USB connector problems on my laptop I put it away and never tried it again. Until Now. Meade 10" LX200 with Televue Powermate 2x, Meade LPI, 41 frames chosen by the Meade Autostar software, stacked in Registax with wavelet enhancement, Adaptive Richardson-Lucy sharpening in Images Plus, final processing in Photoshop Click here to see a medium resolution image.

Saturn, early in the morning of November 8th, 2005 (3:48 am EST to be exact). I captured 8 satellites, according to Cartes du Ciel, and a few stars too! With Televue 2x Powermate. This was a combination of 3 exposures, 0.4 sec at ISO 100, 10 sec at ISO 400, and 30 sec at ISO 3200. I overlaid the three exposures in Photoshop, then erased through the overexposed parts to combine the data and show much more dynamic range than the camera is capable of in any one exposure.

Messier 42, the "Great Orion Nebula", and Messier 43. A combination of a stack of 11 x 5 second ISO 3200 shots for the bright Trapezium area, and a stack of 19 x 30 second ISO 3200 shots for the rest. Click here to see a medium resolution image. Click here to see a high resolution image.

The Moon and Venus, November 5, 2005. Shot at ISO 800 through my Canon 28-135 zoom lens @ 135mm, f/6.3, 3 seconds. The diffraction spikes are optical, from the aperture vanes. Click here to see a medium resolution image. Click here to see a high resolution image.

A 60 degree wide-field shot showing Cassiopea, Andromeda, Pisces, Perseus, Triangulum, and Aries. The Andromeda galaxy, the Double Cluster, and several other DSOs are visible, as well as Mars in the lower-right. This was a single, non-tracking 30 second ISO 1600 shot with my Canon EOS-20D through my Canon 10-22 zoom @ 22mm.

M27 - The Dumbbell Nebula By coincidence, when I imaged this object there was a new star showing, which is highlighted with the two lines in the image. The forums were abuzz with talk about whether it was a supernova, a nova, or just a variable star. Most ended up agreeing it was a variable, but I didn't hear for sure, so I labeled it a nova in the image. 40 x 30 second ISO 3200 subs, Canon EOS-20D on Meade LX200 GPS UHTC 10", f/6.3 FL reducer, unguided, alt-az mount.
