Celestron 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.

Description

Here'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.

Widefield 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.

Description

Orion'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.

Equipment

DSI Pro II behind homebuilt 6" f1.8 astrograph & 10" LX200R @ f 3.3 H-alpha, green and blue filters used (no lums)

Description

In 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.

Description

The 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

Equipment

# Telescope: TMB152, 1200mm FL # Mount: Paramount ME # Camera: SBIG STL-6303 CCD, AstroDon E-Series TruBalance Ha and RGB Filters

Description

Three 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.

Description

The 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.
