About this image

Hi,

Yesterday because of the inclement weather. I decided to re visit an image that I recently took from Fernilee reservoir, on 2017 09 01.

It is mostly centred around the bright magnitude 2.2 star Gamma Cygni.

I part processed this image in St (star tools) to get the balance right, then re - worked it in CS5, with a conversion to mono using.

Image-adjustments-black and white. I then selected the red filter option, to convert to mono.

I think this picture looks considerably better now than the previous colour version. The UHC filter that was used. Has been able to bring out the nebulosity, and shows more contrast in this mono version than in the colour image.

Notice how the object at the top of this picture that looks S shaped is in fact. DWB111. A bright nebula that is more commonly known as the Propeller nebula.

I didn't notice this in the colour image. Which is why I love, monochrome CCD imaging.

Enjoy.
