As such, during the imaging session, I had some real North\/South guiding issues, which show up as slightly elongated stars. This also means that the finer detail in the nebula has been lost, and no amount of post processing wll get that back. I`ll be back again for this target one night, and make sure the guiding is working correctly before I start myimaging sessions.<\/p>\n<p>OTA: Celestron NexStar 8 GPS @ f\/7.(something)<br \/>\nCamera: QHY8 OSC<br \/>\nGuiding: William Optics ZenithStar 66 SD + DSI-C + PHD<br \/>\nImaging: MaximDL\/CCD, 16 x 900s, CLS Filter<br \/>\nProcessing: DeepSkyStacker, ImagesPlus, Photoshop CS2 + Noel Carboni\u00e2\u20ac\u2122s Astro Tools<\/p>\n<p style=\"text-align: center\"><img decoding=\"async\" src=\"http:\/\/www.steves-astro.com\/images\/ic\/ic1396_elephant_trunk_20071111.jpg\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Not overly happy with this image, I trained the autoguiding in PHD while it was a bit blustery, and I think the scope\/mount was getting moved a bit by the wind.
