Next time I shall use ISO 400 or greater, wait until moon is higher in sky which should negate some visibility induced softness and maybe use shorter focal length using TC14E teleconverter instead of TC17E.

Also my first attempt. Not having a long lens I attached my camera to my scope. Giving a focal length of 1500mm. As this gives a fixed aperture of f13 I had to set the camera to ISO800 to get a shutter speed of 1/100sec. Time around 8:50. Sky just going dark. I do not have mirror up so had to use anti shock mode and the additional stabilty of a second tripod. I will take a picture to give you a laugh.
The problem is definately haze. I feel the air has to be clear to the horizon or it will impact on the final image.
Stevie looks at the stars and I keep searching for the Hasselblads left on the moon, hence the picture title.
