lbn672 (Section of soul nebula)
Object Information
LBN672 is a zoomed in section of the eastern side of the Soul Nebula (IC1848) in the norther constellation Cassiopeia. This is a diffuse emission nebula with concentrations of ionized Hydrogen gas and dust.

Upper Rho Ophiuchi Complex (IC4604)
Object Information
Rho Ophiuchi is actually the brightest star among the triplet in the upper left blueish reflection nebula IC4604. A facinating and complex area with dark dust lanes leading off the image into the famous dark Pipe Nebula, bright blue reflection nebula (including IC4605 to the lower right as well) and the more golden yellow IC4606 reflection nebula behind IC4605.

Optics: SV70ED @ f6 Camera: Canon Rebel XT (350D) modified; Type 1a filter ISO 800 Exposure: 7 x 10 min mount/Guiding: G11; ST4 through TEC140 Processing: Dark Subtract & stack in DeepSkyStacker; Levels & Curves in PS CS5; Noise Reduction in Neat Image Location: Camp Oaks (RTMC), CA Date: 5/25/11 Comments: Clear skies. Average seeing. Very pleasant for RTMC.
Antares & Friends
Object Information
This is actually the lower section of the Rho Ophiuchi complex with the brightest star Antares in the lower left (the "eye" of Scorpio). Note the unusually pretty golden-yellow reflection nebula surrounding Antares which is uncommon in reflection nebula. M4 is the bright large globular cluster to the right of Antares and the smaller globular cluster slightly higher is NGC6144. The red emission nebula off to the upper right is Sh2-9 and the faint blue reflection nebula around the bright star in the same area is Ced130. IC4605 is the brighter blue reflection nebula to the upper left.
