The Vallis Rheita

Hi all,

An appauling run of weather broke (briefly) last night. The seeing
wasn't fantastic but is was nice to be out again. Lots of moisture in
the air - my corrector plate was fogging every few minutes. Here are a
couple of shots of the Vallis Rheita and a capture of Petavius from
the session...

Pete,

Lots of very fine detail on difficult targets. Don't knock the humidity,
for it usually means good seeing. I am always delighted to see humid
conditions with some fog since my skies are then perfectly still and I
can crank up the power when observing due to usually very good seeing.

Here are my attempts in relation to Petavius and Rheita:

Fingers crossed for next weekend as far as Luna is concerned.

Please keep 'em coming!

Anthony.

Sharp Pete, will you be entering them in the Cloudy Nights
competition ?
My eyes are playing up, I keep seeing the craters as domes ;-(

Oh, I'm glad it's not just me! I was looking at Pete's photos when my other
half came into the room, and when I pointed out my brain was reversing all
these craters he said he could see them normally. But as we talked about it,
and he started thinking about them being reversed, his brain did a sort of
flip and suddenly he too was seeing them as domes. And yet I can see
Anthony's photos of the same region the right way round. What's going on
here?

It's because the light is coming from the bottom right. Most graphics
and images show the light coming in from the top left and your brain
gets used to that and tries to make sense of images in which this is
not the case (like mine here) by reinterpreting the craters as domes.

Really nice pics. Expensive 640x480 cam. ;-)

Glad to see some decent planetary cameras come into the market for
astro users, but I sure don't want to pay the price of entry to play
along. :-(

Ah.... right. I just copied your photo and rotated it through 180 degrees,
and lo and behold, the craters have become properly concave. Thank you! This
has been an ongoing puzzle for me for a while with lunar photos.

(I'm now off to do some experiments, photographing everyday objects with the
light coming from the bottom right...)
