North American Nebula
This image of NGC 7000, the North American Nebula, was taken by Douglas George from his observatory near Ottawa, Ontario, Canada.
Eta Carinae
By Australian astrophotographer Luke Dodd... "Despite being new to CCD photography, I am very impressed with the ease of stacking and colour manipulation of images with your program. My first ever tricolor photo, a shot of Eta Carinae, was taken with the ST11000 through a 5" refractor. Considering I spent no time learning to use the program, I cannot believe how quickly I combined the RGB images to produce such a nice image, all because your program is so intuitive!"
Orion Nebula
This image of Messier 42, the Orion Nebula, was taken by Matt Russell on November 17, 2001 in Crosslake MN. He used a Takahashi FSQ-106N with an SBIG ST-10E and CFW-8. It is a combination of twenty 2-minute luminance, five 2-minute red, five 2-minute green, and seven 2-minute blue exposures.
Galaxy M51
This image of Messier 51, the Whirlpool Galaxy, with NGC 5195, was taken by Douglas George from his observatory near Ottawa, Ontario, Canada.
Mars
This Mars image was taken by Russ Lund using an SBIG ST-5C camera. The exposure was 0.75 sec red and green, and 1.00 sec blue. He used the sequence feature of MaxIm DL to take 30 images of each. He then picked the best of each color. A gamma stretch was applied to blue, followed by unsharp mask, color combine, and color smoothing.
Moon Mosaic
This moon mosaic was taken by Gregory Terrance using a 12.5" Ritchey-Chretien and IMG1300 camera. Image assembled using MaxIm DL's mosaic command.

Lunar Eclipse
This image of a lunar eclipse was taken by Douglas George from his observatory near Ottawa, Ontario, Canada.
