This version of the Dumbell Nebula was taken from my driveway under clear, but mag 3.5 skies! As a result, 134 minutes of total exposure was used through an IDAS filter on the 12"SCT. Some evidence of field curvature is also evident on this cropped image. The scale is rather large, owing to the f/5.65 speed on the 12". Guiding was performed by the Tak Sky90, 2x barlow and the MX7C camera.
