Please any hint on those. I mean the dark shadows on the left of the crater. I didn't yet finish classifying the image, although I've added it to my favourites, but it probably appears only when finished (like galaxy also). So, apologize for the small images.

I think they are just the shadows inside the crater tsiehta. Looks like the Moon was illuminated from the botton left for this one. Would that be right?

Thanks again jules. The first dark shadow looks much fuzzier than the second, so I thought it might show something unusual. And yes, illuminated from left.

I have two questions to go with this image:

Is the area on the bottom left a boulder field or something else?

Is the bright white area on the right centre a crater?

Looks like a historic river, any advise please if it is a feature and if yes, which category. Thanks.

Edit: Is it a huge 'sinuous channel'?

I'm hoping some of the experts will wander in and help us out soon but meanwhile I'd say yes to the boulder field and the bright area looks like a recent impact of some kind. Crater or lander? Probably a crater but the lighting isn't helping is it? There's a suspicious looking spacecraft type boulder top left too. :-\

Or a dark ray from the crater top right? Don't know!

Not sure what to make of this. I noticed five dots (boulders, small craters?) in a row.

I've taken a screen shot which I have attached - hope it shows up all right.

Hi Jules

I cropped the picture very small so it only shows the 5 dots. I could find the favourite and post that if it helps.

This image shows five boulders or something in a row beneath the crater on the right-hand side in the centre.

Is this a crater chain or boulder track or something else (or nothing!)

I see them. Might be a crater chain I suppose - not really familiar with spotting them yet but it's a striking feature I think I would certainly mark it as something - crater chain or other.

Sorry if this question is in the wrong thread. How do I classify the little white bits? They look like points of light, if anything.  :D



I should think that 'most' of those are boulders... obviously very difficult to say - especially without any indication of picture scale.

YES!  We need some kind of scale on those pictures!  And a zoom tool too.

I think the pictures are zoomed as much as they can go (as Tommy mentioned in another thread).

I use a magnifying glass sometimes  :D

A scale rule below each image would be handy.
