Nebulae & Galaxies
LocationLos Alamitos, CA
EquipmentCelestron Nexstar 8 GPS, SX-AO @.2-.4 sec guider exposures, CS 10 nm HA filter, Baader 9.5 nm OIII filter with SX H9; IDAS LPR filter with H9C.
DescriptionHere's an interesting juxtaposition of what appear to be two toroid-shaped planetary nebulae with layers of concentric outer shells: The little dumbbell M76 on the left appears edge-on, while the ring nebula M57 on the right appears face-on. M76 was imaged in December using narrow band HA and OIII filters while M57 was imaged in August with a combination of HA and RGB filters.
EquipmentWidefield image taken with Stellarvue 66ED and William Optics .8 reducer. The camera was a Canon Digital Rebel XT. The mount was a Losmandy G11. Autoguided with a Meade DSI.
DescriptionOrion's belt consisting of the stars Alnitak, Alnilam, and Mintaka. The horsehead and flame nebula accompany Alnitak and the faint Teardrop nebula is around Mintaka.

EquipmentDSI Pro II behind homebuilt 6" f1.8 astrograph & 10" LX200R @ f 3.3 H-alpha, green and blue filters used (no lums)
DescriptionIn this 4 frame mosaic I tried to highlight the faint H-alpha wisps that surround the M42,43 and NGC1977 nebulas. 20+ x 2min subs were stacked using a full apature H-alpha filter with the fast astrograph to capture these frail smokish threads and the larger 10" scope was used for inner detail. Each was scaled ,layered together and ballanced fro color in PS.

EquipmentTulip Nebula and Surrounding Nebulosities in Cygnus 21 x 600 sec Raw with Darks _ Flats-Calibrated with ImagePlus HUTECH MODIFIED CANON XTi (Canon Rebel XTi (400DH) spectrum enhanced camera with built-in astronomical UV/IR blocking filter (Type Ib) ) @ISO 1600 Custom White Balance Scope = Meade 5000 ED 80 with .8 Focal Reducer on Top CGE 1100 Guiding with PhD Process with ImagePlus and PhotoShop Graident XT Teminator
DescriptionThe image shows Sharpless 101 Nebula, a faint emission type nebula known also as Tulip Nebula on right with n Cygni to far right in the well known Northern Cross asterism. Surrounding nebulosities also contain 25 and 28 Cygni and NGC 6871 an open star cluster, also idenfied as GC 4548, h 2067 and Struve 2630

EquipmentHomebuilt 10 inch Newtonian(F4) and mount in dome. Camera: Modified ToUcam840K ProII with UV-IR CutFilter. Exposure: 5 min unguided, +dark frame processed in RegiStax 4.0
DescriptionBubble Nebula is an expanding bubble of gas with a diam of abt 10 ly.
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.

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.

Equipment57 of 60 exposures at 300 seconds each for a total exposure time of 4.75 hours. Unmodified Canon EOS Rebel XT (350D) taken through an Astro-Tech 66ED refractor while piggyback on top of a NexStar 11 GPS that was used for autoguiding. Captured and processed in Stark-Labs Nebulostiy and post processed in Microsoft Picture It! V6.
DescriptionUnder dark skies, this image clearly shows the spiral structure and over two dozen HII regions are visible.

EquipmentImaged with a 178mm f/9 Astro-Physics refractor and a Canon 20Da DSLR camera (ISO 800) on a Paramount ME. Thirty 120-second exposure were taken and aligned, callibrated, and combined in Images Plus 2.82 and processed in Adobe PhotoShop CS2.
DescriptionMessier 42, the Orion Nebula: A series of 2 minutes exposures were taken to avoid overexposing detail near the bright core of the nebula.

DescriptionNGC 2264, the Christmas Tree Cluster and the Cone Nebula. 3 hours and 20 minutes with darks/flats and bias frames. The Christmas Tree Cluster (also known as Open Cluster NGC 2264 or the Xmas Tree Cluster) is an open cluster in the Monoceros constellation.
