2. 40 x 30 second exposures in LRGB of Altair in the Aquila constellation, located about 17 light years away. Altair is a rapidly rotating, Type A, Main sequence star with about 1.8x the mass of our sun and about 1.8x the radius. The star completes a rotation in only 9 hours which creates a strong centrifugal force that causes the equator of the star to bulge out, the equatorial radius is 25% longer than its polar radius. By comparison our sun takes 25 days to rotate. [Credit : Own Work (Alexander Segler)]
