As I saw the moon break out of clouds in the Dallas/Ft Worth area I ran to set up a 4 inch refractor. I figured why not have a background suitable for the heavily light polluted metroplex, so I chose bright orange. The sketch had to be quick because of the clouds were even quicker. With the fast sketch 1/2 done, the clouds rolled over, but their color was strange because of the reflected light pollution. So the overlay of browns and yellows was what I saw, where even clouds get affected by city glow, which, of course, serves little purpose except to render the deep night sky unseeable. Nevertheless, the period was fun, and the sketch is what it is. Roland

Roland,

I love this drawing of the moon in the orange metro-Texas sky.
I am not in favor of the reason for the orange sky but the sketch is great. :bow: :cool:

Frank :)

Roland,

An en excellent observation of a hazy orange Moon observed over a metro sky. It reminds me of an observation of the Moon during brush fires over South Florida (below). Thank you for sharing it with us all.

Carlos

Thanks guys. It was fun. The orange sheet of paper was the first out of the folder, so I went with it. Think of it as a brand of disfavor for the metroplex's disregard for the night sky. Roland

Roland, this is a fascinating rendition of a very grim* looking moon with apocalyptic undertones.

*or perhaps just grimy! Well-rendered in either case. :waytogo:

Thanks Eric and Jay.

The sketch also brings to mind false color sketching -- a parallel to false color imaging. Once in the past I did the Altai scarp with bright yellows (as white), greens (as mid tone), and blacks for the darkest shadows. It produces a mixture that is equivalent to false color imaging, which is common in astronomy. For those who have not tried it, it actually helps the study of some lunar targets. Somehow the mental re-assignment of colors to a grey-toned moon enhances study and then the results get translated to the sketched moonscape. Would like to see someone else try this. I found it interesting. It also permits interesting assignments of of a wide variety of color sets.
