The prize for your patience is a better photo

Please sit down and watch this! This is the price for the patience of some astrophotographers. The difference in S/N (signal-to-noise) ratio and the count of visible details is really noticable if you compare both Ha narrowband photos of NGC1893 in Auriga shown above. The first astrophoto is the result of an exposure of 960 seconds. The second one is a median stack of 5 x 960 seconds 2 x 600 seconds. It's incredible isn't it?
