Veil Nebula Redux, 10 August 2008

NGC 6960, the “Western Veil” portion of the nebula. Reshoot of last week’s image with a higher ISO. Even with only half the exposure time, the nebula is much brighter. I’m really getting the hang of this now.

Shot 10 August 2008, ISO 800, Exp 5x5m, f/5.2, Canon EOS 5D & Televue NP127is, from Rock Springs Parking Lot, Mt. Tamalpais State Park.

Moon, 9 August 2008

The moon again. I shot this one mainly to determine the infinite focus setting--the moon is just about the easiest object to focus on as you can readily see minor changes in detail at different settings. I also used it as my first experiment with flat field support frames.

My Imaging Setup

Main Telescope:  Televue NP-127is, 127mm (5-inch), f/5.2 (660mm focal length) apochromatic refractor.

Guide Scope: William Optics, 80mm, achromatic refractor.

Mount: Takahashi EM-200 equatorial mount.

Camera: Canon EOS 5D, Hutech modified with Canon IR filter replaced with enhanced H-alpha filter.

Portion of the Veil Nebula

NGC 6960, the “Western Veil” portion of the nebula. It is very faint and looks like a horizontal wisp of cigarette smoke below the bright star in the center of frame.

Shot 3 August 2008, ISO 100, Exp 5x10m, f/5.2, Canon EOS 5D & Televue NP127is, from Rock Springs Parking Lot, Mt. Tamalpais State Park.

M31 Andromeda Galaxy

A flawed, but pretty cool image. I really need to start taking flat frames to eliminate the gradients and the interference by dust particles on the lens and sensor cover.
