Emission nebula IC 410 and an open cluster, NGC1893, inside it are located in constellation Auriga about 12.000 light years from my home town Oulu, Finland. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893.
"Cosmic tadpoles" are potentially sites of ongoing star formation, they are about 10 light-years long.
Emission from sulfur atoms is shown in red, hydrogen atoms in green, and oxygen in blue hues in this false-color, narrow band composite image above.Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.
Optics, Meade LX200 GPS 12" @ f5
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera 8Hz
Image Scale, ~0,8 arc-seconds/pixel
15 x 1200s exposures for the H-alpha, emission of ionized Hydrogen = 5h
6 x 1200s exposures for the O-III, emission of ionized Oxygen = 2h
4 x 1200s exposures for the S-II, emission of ionized Sulfur = 1h 20min.
