Unless otherwise noted, these images were captured with my Canon EOS digital cameras or Meade Lunar/Planetary Imager and Meade 10" LX200 GPS UHTC 2500mm f/10 telescope from my light-polluted south Florida home. I used my own Astronomy Tools actions, AstroFlat Pro plug-in, and StarSpikes Pro 4 plug-in on these images.

Two Days Past a Super Moon, September 10, 2014
A Super Moon is when the moon happens to reach Full stage at the same time it's closest to the Earth, and so it looks large in the sky. This image was taken almost 2 days past the Full phase, and you can see the edge starting to fall in shadow at the upper-right. This image is a mosaic of 18 separate and overlapping 10 megapixel images from my Canon EOS-40D digital SLR set to M (manual) mode, captured as raw .CR2 files and converted and stitched together in Photoshop CC 2014.2. I mounted my dSLR 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 the camera to the 2" telescope eyepiece tube. Effective focal length in this configuration is 5000mm f/20. Using Live View mode on the camera to frame the images, I swept across the surface in a zig-zag fashion, trying for about 1/3 to 1/2 overlap between frames. I triggered the shutter 8 times manually at each position with my TC80-N3 remote timer/controller, allowing the telescope to settle (stop vibrating) between shots. After I chose the sharpest image from each set, Photoshop CC's Photomerge feature made quick work of the stitching. Since it was taken at the camera's most noise-free setting (ISO 100), the data is highly accurate, and thus I was able to strongly increase the color saturation via Photoshop's Image - Adjust - Hue/Saturation function. Thus the colors are real, indicating different mineral compositions of the lunar surface. Click here to see a medium resolution image. Click here to see a high resolution image.

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. 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 color saturation via Photoshop's Image - Adjust - Hue/Saturation function.

M68 - Globular Cluster.
Stacked from 34 exposures of 15 seconds at ISO 1600 with 0.63x focal length reducer / field flattener on my LX200 telescope. |
Wide starfield shot in Auriga, showing M36, M38, NGC1907.
Stacked from 9 exposures of 10 seconds at ISO 800 using my 100-400 zoom lens 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. |
The Double Cluster, NGC 869 and NGC 884.
Canon EOS-20D and Canon 100-400 zoom lens at 300mm, piggybacked on top of my telescope. |

The answer to life, the universe, and everything... Douglas Adams was off by 5! NGC 2169, The "37" Cluster. 26 x 30 second ISO 3200 subs, with f/6.3 FL reducer. |
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.

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. |
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. Taken on October 25, 2005, just
after Hurricane Wilma blew out all the power and darkened the skies.

An almost 90 degree ultra wide-field shot of the dark south Florida skies
on October 25, 2005, just after Hurricane Wilma blew out all the power. We've never seen stars
like this here before! Taken through my Canon 10-22 EF-S lens @ 10mm, 30 seconds, ISO 1600, f/3.5.

A combination of two exposure stacks, one for the planet and one for the background stars and moons. |
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.
