  1. Thanks for the comments, I have now added dark frames into the mix, or more correctly I have subtracted them, to get a final result. Hope you like it and thank you to Uranium235 for starting the thread. AlanC.
  2. Thanks for that, I am in the process of shooting a set of darks right now; its below freezing outside so it matches well the conditions when i took the data last night. Can't do anything about the slightly soft focus in the light-frames nor the light-halos around the stars from the misty atmosphere here in Scotland last night but I will calibrate the image once I have suitable darks and flats. Still, the image gives a good idea of the field of view at 350mm focal length. Alan C.
  3. Hi, I'm a newbie to the forum but saw this post about the 178 camera. Don't want to take it over but thought I might show an ASI178MM-Cool image taken last night with a William Optics Star71mm at 350mm focal length; helps with an idea of field of view of this chip? For info, this is a stack of 18 guided images at 240 seconds per exposure, no darks, no flats. Hope that's of some interest, Alan C.
