Yeah, I was using the Pentax digital in colour. I had the filter in and it made it easier for the camera to auto white balance on some shots as the manual settings are a bit screwy on this camera.
I was checking out the usual nebulae suspects and swung around to the moon and just happen to leave it in.
The close up of Clavius is a bit blurry but, all in all these moon shots are a hell of a lot better than my planet ones!
