marcus 2013

Another last lens test.

Knew I'd forgotten something - the no-name 500mm!

Took this tonight, 1/1250th f8 on the D90, cropped and contrast/brightness adjusted. Much higher resolution than my previous astronomical efforts, and I think the lens is showing its limitations a bit. I recently read somewhere about a special blue filter for moon photography, I really must investigate, though I wonder if any ordinary blue filter will also help - I might have one, though probably not the right size for this lens (72mm filter). I should also try this with a tripod etc. for better results.

Tonight's full moon

Later - looks like the moon filter is for eyepieces, not cameras.
