M11, The Wild Duck Cluster: Captured using a 10-inch f/4.8 reflector, Vixen Atlux mount with PHD auto-guiding, and a Canon 50D DSLR camera. I took 30-second subframes, integrating them with corresponding dark and flat field frames to minimize noise and vignetting. The total exposure time amounted to 15 minutes.
M27, The Dumbbell Nebula: This image was obtained with a 10-inch f/4.8 reflector, Vixen Atlux mount, PHD auto-guiding, and a Canon 50D DSLR camera. The camera was set to ISO 3200, capturing 30-second subframes, which were then merged with matching dark and flat field frames to lessen vignetting effects. The cumulative exposure time was 20 minutes.
M27, The Dumbbell Nebula: The image is a composite of data from two cameras, a Canon 50D DSLR and an Atik 383L mono CCD, utilizing narrowband filters: H Alpha, OIII, and SII.
