Telescope?  I ain't got no steenkin' telescope. This was taken with a 
1970s-vintage Vivitar 300/5.5 and a Tokina teleconverter on a 
tripod-mounted Oly E-M5, so equivalent full-frame focal length is 
1200mm.  The posted picture is about 64% of the frame by linear 
measurement, or 41% by area.

There was a thin haze in the air, but this being the Pacific Northwest, 
I decided to seize the opportunity of a relatively clear night anyway. 
The original image was a bit soft at 1:1.  I extracted the green 
channel*,  ran it through Focus Magic, which really brought out the 
details, then some conventional rotation, curves and contrast enhancement.

* Drastically reduces CA-related softness, and the green channel has 2x 
more pixels than the others. This was visibly more effective than just 
using Capture One's "color fringing" compensation.
