Thanks.
Yep, one moon photo looks very much like the other... hardly a subject with scope for interesting composition
I do find the moon a handy reference for testing equipment on, and that's basically what I was doing.
Using mirror lock-up, I was oblivious to what was passing across the moon, so a surprise when opening this on pc.
Trouble is, everyone thinks it's a photoshop job
...though I'd hope to do a composite a bit better than this in terms of size of the plane and maybe placement.
cheers,
Andy
