 There are a few spectacular objects in the sky with very bright stars in the immediate vicinity, making photography of them difficult. This is one of them, NGC2024 in Orion, just to the North east of 2nd magnitude Zeta Orionis. The bright star is off to the lower right, making reflections within the optical system. This is the first time I have been able to get the entire nebula using the 12.5" and CCD. The previous camera, the ST7E would only get a fraction of it.

The color of this object is very curious indeed. It is not the usual pink or reds seen in most emission nebula. The addition of a large amount of obscuring dust imparts a more orangish hue to the nebula, as seen here. This nebula in addition does not respond well to nebular filters because of the dust, making viewing of this object even more difficult.

Shooting Notes: This object is an RRGB, using the red filter for the luminance in a further attempt to isolate this nebula from the bright star. This tends to make red stars look brighter, and blue stars dimmer but more saturated.
