  1. Hey folks!

    Equipment I used:

    * Lunt 100mm Double Stack for hydrogen alpha
    * Lunt 100mm white light
    * ASI 290mm camera shooting at 204 frames per second

    To capture the image I used two different telescope combinations:

    1) White Light configuration to capture the ISS in high detail. This allowed for a low shutter speed at approximately 1/14000th of a second

    2) A double stack hydrogen alpha set up that allowed me to capture the chromosphere of the solar surface

    Any questions please feel free to ask, and thanks for looking.

  2. ^^This is super cool. Exactly the kind of stuff I joined this sub for. Well done friend.

    Also the Hydrogen alpha is BEAUTIFUL!
