Description:
First successful attempt at taking a sunset image in the hydrogen alpha wavelength. Despite some thin clouds, the surface features can be seen clearly, including the sunspot in AR2833, a long filament nearby, and a few faint prominences near the limb. This is a single frame extracted from the video sequence, with a little bit of sharpening, enhancement, and false color application. The result is beyond my expectation, given that the Sun was low in western sky at just 13° above horizon.
