It is what it is!!
I took this photo last night with the following:
Sigma 70-300mm 2.8f
Aperture set at 13f
Exposure time: 1/80
Focal Length: 420 (I put my 1.4x tele-extender on the lens)
I set all this up on my tripod.
After I took the picture, I cropped the photo and sharpened it some in Photoshop CS6. Otherwise, “It is what it is!!”
