NGC 7331

The Horsehesd Nebula

The Horsehead Nebula

This was taken in January 1999 again with the ST-7 and LX-200. With no focal reducer so the scope is set at f10. A combination of 2 x 30min exposures with no image processing. Temperature is set to -17ºC and the ST-7 is in BIN 2 mode. Dark, Flat fielding and Bias all applied.

The faint lines coming from the left I thing are from light pollution from a neighbours house.

The remarkable Horsehead is a dark globule of dust and non-luminous gas obscuring the light coming from behind, especially the moderately bright nebula IC 434. It part of an interesting region of diffuse nebulae, which belongs to a huge cloud of gas and dust situated 1600 light years away in the direction of the constellation Orion.
