Hi all.
Here's another hi-res mosaic of the Moon's surface showing the vast
filled crater Ptolemaeus and smaller Albategnius. Notice the tiny
craterlet atop the central mountain peak in Albategnius. You can also
see a number of filled but sunken craters in the floor of Albategnius,
brought out quite well under the low Sun angle.

we recently acquired a new C14 and now know why you have
one. Superb instrument.

I'm still astounded that it's possible to get such superb photos from an
earth-based telescope in the hands of a private individual rather than a big
observatory. Amazing stuff, Pete.
I can't quite get my head round the scale, though. Can someone tell me,
roughly, the diameter of the largest crater? Thanks.

Hi Ally,
Ptolemaeus is 153km across.

Amazing image, Pete - had to stow that one for future
reference.
Thanks for posting,

Superb as always Pete
When are you going to image ALL the apollo landing sites for us?
Cheers

Funnily enough, the reason I've got a lot of lunar stuff at the moment
is because my last lunar project was to do just that. I'm just sitting
down and sifting through the image as I write this...
Spooky Andy!

Hi Pete,
Well you know what they say! "Great Minds Think Alike"
I always enjoy looking at your images, and I can see why you inspire so many
others to go out there and have a go.
As for me, you know I am very busy and I never get the chance to put the
hours in that you do, your images are a testament to that and your
expertise. Long may it continue and thanks for sharing them with everyone..
When you do get your "Apollo" portfolio together maybe you would allow me to
use them and credit you with them in my "One Small Step" lecture about the
Apollo Missions.
All the best
Andy
