DescriptionPart of the eastern half of the Veil Nebula, it is directly south and basically attached to NGC 6992.The filamentary structure is composed of mostly hydrogen gas, with enough oxygen III to provide a pretty green counterpoint to the red hydrogen alpha emission

Locationnear Bolu, Turkey
Date26th December 2007
EquipmentCanon EOS 5D camera at ISO 3200, 100-400 mm lens at 400 mm, composite of 1-minute exposure f/5.6 and 2-minute exposure at f/11 to prevent Mars' glare. All system piggybacked on an 8" Meade LX10 SCT.
DescriptionMars at opposition passed 2.5 degrees north of bright open cluster M35 and its companion NGC2158. This is the second close pass of Mars, thanks to its retrograde motion, the first was in early October and the last will be in mid-March.

EquipmentCanon 30D with Sigma 30mm lens stopped down to f/2.8, exposure of 15 seconds.
DescriptionAt Technion, Haifa, I had an opportunity to go to the Negev Desert and take a picture of 17P/Holmes. The sky was slightly illuminated by the waining Moon.

LocationJMSM Observatory, Mayhill, NM
DateOctober 29 through November 7, 2007
Equipment# Telescope: TMB152, 1200mm FL # Mount: Paramount ME # Camera: SBIG STL-6303 CCD, AstroDon E-Series TruBalance Ha and RGB Filters
DescriptionThree panel mosaic of the California Nebula. Exceptionally deep (both in detail and color) and much higher resolution than normally seen on this object (due to the mosaic at longer focal length). Full resolution image is ~5800x3000 pixels. Image is a combination of Ha and RGB data. The Ha data was used for the nebula in the red channel (100%) and partially in the blue channel (15%). The red data was used only for the stars in the red channel. The green and blue data were used for the entire image. Total exposure time for the entire image is 26 hours 18.2 minutes.
LocationLos Alamitos, CA
EquipmentTakahashi FS102, SX-AO @.2-.4 sec guider exposures, CS 10 nm HA filter-SX H9, IDAS LPR-H9C, G11 HA 14x20 min, RGB 32x20 min.
DescriptionThe Bubble Nebula in HA RGB. LPR and HA filters combined with extended exposure time (15 hours) were used to combat heavy suburban light pollution (Bortle white). The HA filtered images were used to enhance the nebula, tighten the stars, smooth the background, and eliminate light pollution.
