Blank Spot on IR

  • jdcall by jdcall

    Hello, all. Just a question as to what something could be. In the DSS2 IR image you can see pretty consistent brightness except at the target and a dark spot to the lower left of the target. Any ideas as to what could be causing this?

    The dark splotch? I think that could be an #artifact from when they scanned the DSS plates, we've seen a few of those

    The dark spot looks like a speck of dust most likely.
