Enlargement of straight line feature in petavius

Imaged on June 18 at 2030 UTC.


Telescope: 8" f10 Meade LX200.

Camera: PC23C video camera from Super Circuits at prime focus, modified to prevent video gain from rising on small bright targets.

Capture device: ATI All In Wonder Pro video card at 640 by 480 resolution.

Processed with SkyPro (now CCDSoft) to stretch the contrast and apply 10 pixel unsharp mask. Note also that the unsharp mask has revealed that I probably have an impedance mismatch somewhere in my video cabling.... as indicated by the vertical shadows (ringing) along the right edge of the image. This is the right edge of the original frame. Could also possibly be an artifact from the video capture routines?
