Submitting images: When submitting images to TA please send them as an e-mail attachment and please try to use the following filename format: object_yyyymmdd_hhmm_observer.jpg where object is the name of the object, yyyymmdd, hhmm is the date and time of the exposure (the hhmm field is optional) and observer is a unique observer code (say your initials). It is also a good idea to include details of the telescope, scale, orientation, camera, filter etc as annotation on the image.
