NGC7000

DESCRIPTION:
http://en.wikipedia.org/wiki/North_America_Nebula

TECHNICAL NOTES:
This is a single 121 seconds exposure with an unmodified Nikon d3100 DSLR camera. It has been taken under light pollution WITHOUT any LPS filter. Note the wonderful star colors. The nebula has been taken out using the "Tone Mapping" technique, since the original filter of consumer DSLRs is optimized for daylight and it blocks the red channel.

EQUIPMENT:
Telescope: 385mm (f/3.65)
Guider: SBIG ST7XME on a 355mm (f/6) scope.
Mount: JPZ
Software: Aperture v3.1.2 (Mac). Only histogram adaptions has been one in the NEF (raw) file.
