Hey folks!

[Captured in Hydrogen Alpha – False Colour Applied](https://photos.smugmug.com/Astronomy/Solar-System/i-gRkgMBW/0/LnWmk24qbVJnRhdG57fVvKgr8pjmNVCgsdk9nV6Rt/X2/ISS%20Transit%20Hydrogen%20Alpha_Colour%20-%20April%2019%2020224-X2.jpg)

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.

Dunno why but that picture makes me feel really small….
