M20 Trifid Nebula - Test image

Anza, CA

Another test image with the modified Digital Rebel. Taken through a Vixen VC200L at prime focus, focal length 1800mm and f9, no reducer, mounted on a Losmandy G-11 with a Borg 77mm achromat guide scope using a Meade LPI and GuideDog software to guide the mount. This is 6 exposures of 3 minutes each taken at ISO 800, processed in Imagesplus, with dark frame calibration, digital development, color balancing and almost all editing, a little tweaking in photoshop, mostly noise removal. Almost full moon about to rise. I will go back and reimage this at a later time to get more exposures as this few does not really do it justice.

Digital Rebel, modified

other sizes: small medium large original auto
