DateAugust to October 2007
EquipmentTakahashi FSQ 106N on a Losmansy G11/Gemini. STL11000M with Astrodon LRGB and H-Alpha filters. Guiding with a MiniBorg 45ED and the SBIG Remote Guider Head.
DescriptionIn about 3.900 light years distance, embedded in an band of dark nebulas, lies the Cocoon nebula. This image shows a detailed view of the neighborhood with dark clouds of matter that are not so dark at all. Red bands of light emitting gas cross the field in this 10.5 hours exposure of IC5146. While taking the image a badger tried to keep me off from his patch, but at least he accepted me as not to dispute his territory but only in our rare clear nights.

DescriptionLBN 667 is the designation of the nebula, also known as Sharpless 2-199. Open clusters CR 34, 632, and 634 (in the head) and IC 1848 (in the body) are embedded in the nebula. The object is more commonly called by the cluster designation IC 1848. Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area. This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".

EquipmentThe imager was an SBIG ST10XE through a Takahashi TSA102 reduced to f/5.98. It was guided with a Meade DSI Pro II through a piggybacked Celestron Onyx 80ED. The mount is a Takahashi EM11 Temma 2 GOTO Jr.
DescriptionThis image is the core of IC 1805 "The Heart Nebula". It is a monochrome image shot through a 13nm Astrodon Hydrogen Alpha filter. 9, 10 minute subs aquired in Maxim DL. False color added in Photoshop then the Ha image was layered again as luminance. The "frilly" detail reminds me of the fractal created by the Mandelbrot equation.

DescriptionProbably the most difficult object I have attempted is LDN1622 or the sometimes “Boogieman Nebula”. This interesting and rarely photographed dark nebula lies just across Barnard’s Loop from M78 in Orion. The image was a combination of 112 x 2min frames taken over 3 nights in mid September, a lot of integration time to bring out only some of the detail. I hope this winter as Orion rises higher in the sky I will be able to add more detail and perhaps color to this image.

EquipmentI used a Celestron CGE 1400 at f/7 and ST-402 ccdcamera. Telescope was autoguided by PHDGuiding using a ATK-1HS webcam on a AstroTech AT-66 f/6 refractor. Image is a stack of 6 5-minute subs in Luminance, and 3 3-minute subs in each red, green, blue.
DescriptionImage shows a closeup of the ring structure in M57.

DescriptionMessier 27 - The Dumbbell Nebulae in the constellation Vulpecula, was the first planetary nebulae ever discovered. This planetary nebulae has a magnitude of 7.4 and is located 1,300 light years from earth. The collapsed central star is clearly visible in the center of the nebulae and has a bluish white appearance.
DateNov 22, 2006 about 9pm
EquipmentThis was shot unguided through am 80mm f/6 Stellarvue Nighthawk II on a modified HEQ5 mount. The camera was an un-modified Canon 350D at 800ISO.
DescriptionThis was shot on the first night with both the scope and camera and was my first attempt at digital astrophotography. Only 4 subs were taken, 3 of 180 seconds and 1 of 240 seconds with 3 dark frames. Processed with DeepSkyStacker, CS2 and The GIMP.

EquipmentOrion ED80 Unmodified Canon RebelXT 350D
DescriptionPrime Focus 92-30 second images at ISO 1600 Stacked with DeepSkyStacker Processed with Photoshop CS
DateAugust 19-20, 2007
EquipmentMain imaging scope was the William Optics 66SD connected to a modified Canon Digtal Rebel (aka 3ooD) and Baader MPCC / IDAS LPS. Guide scope was the Orion ED80 and DeepSpace StarShooter all riding side by side on the Atlas EQ-G GoTo controlled by EQMOD w/ pulse guiding via PHD
Description33 subframes at 4 min each stacked in IRIS and final processing using PS CS2 and GradiantXterminator
Date9/2/07 and 9/3/07
EquipmentDSI Pro II on 10"LX200R at f/3.3. Guided with DSI II on Orion ED80. Schuler narrowband filters.
DescriptionThis closeup of NGC 281, an emmission nebula in Cassiopeia also known as the PacMan nebula, was taken over 2 moonlit nights using narrowband filters. The Bok globules are immense molecular clouds which absorb light from the main nebula and can be star forming. The total exposure time was 7 hours, 3 hours of Ha and 4 hours of OIII with 5.5 minute subexposures.
