Object: Orion Nebula, M42, M43 
Date: November  20, 2002
Equipment: William Optics FLT110 at F/6.5, HX916 CCD, G11 mount, ST-4 autoguider
Exposure: H-alpha (see comments): 2x15min and 5x2 min
Processing: Photoshop, curves, layers and mild unsharp mask. No dark or flat frames applied
Comments: Image was taken within 30 of a nearly full moon. The moon was practically within Orion for most of the exposure (see it here). Light clouds and haze dominated the air. Humidity was at 92%. Seeing was unstable and varied between 4" and 5" FWHM. Some dew was found on the objective after the exposure despite the dew heater.

Exposures were taken through a combination of an IDAS LPS filter and an IR-blocking Red filter from SBIG.

Description: Orion Nebula is part of a large gas and dust cloud located in the Orion Constellation. It is one of the closest stellar nurseries to us at about 1,500 light years. The whole cloud easily spans over several hundred light years.
