[APML] Unwanted light in my astrophotos
Recently I have been seeing light in a form similar to a crescent moon in my C14. This crescent shape has been appearing in my astrophotos. When I see this light in my eyepiece it always is very close to some bright star. As I move in the direction of the bright star, it becomes clear that the light is coming from the star. You can see the crescent actually move into the star as I move the telescope so that I am focused on the star. I have checked to see that my focuser(a JMI) and camera (a 35mm nicon) are tightly attached and they appear to be. What is this and more importantly, how do I get rid of it? Any help will be greatly appreciated.
