I don't get the whole nebula in, but I like the detail the longer focal length brings out. This is a picture
of the Rosette Nebula at about 1200mm FL with an AP180EDT mounted on an AP900GT guided by a QYH5 finder scope
guider using PHD guiding. The camera was a modded Canon XS at ISO1600 with an Astronomik CLS clip-on filter
installed. 6x20 minute exposures (2 hours total), no dark frames (temperatures in the 20s F), stacked with
Deep Sky Stacker, final processing PhotoShop CS4.
