Remarkable scale images for the C8 at f6. The Aristarchus image is especially fine. Nicely done 8)

These magnificent, extremely detailed photographs ( or images, I guess I should call them), when compared with the selenographical results using an 8" reflector back in the early 1960x, make me wonder whether there is really any point in visually looking at the Moon now, except for pleasure and during eclipses or occultations. Back in those days observers were looking for and arguing about fine details, relating to domes , craterlets, rilles etc, and here before our very eyes one can see everything and even more! Regards maf.

No not cropped (apart from the edges).

I'm guessing that the GPcam has quite small pixels?
