I thought I would break the ice on the astronomy section with this view of the crater Janssen taken some time back. Also clearly visible is the Rheita Valley at centre, and the "twin" craters of Steinheil and Watt towards the top. Janssen measures over 100 miles from crest to crest and has a curious raised floor crossed by some clefts. Notice the curious "horse shoe" shape ridge in the crater Fabricius on it's floor!

Well that's some opening shot John! I find myself more fascinated by the Moon the more detail I look at - I used to know the names of the most obvious Maria and that was it, but technology allows us to see and image much more detail - I doubt that an amateur photo taken through a small scope 10 years ago would have shown the Rheita Valley - we've come a long way!

Great image John. With the terminator at that angle the image looks very 3-d with so much depth. Janssen looks great with that nice cleft cutting across the terrain with that intense spot in the middle. A joy to look at  Smiley

Thanks Dave, would you believe an ETX90mm and Philips TouCam? It's made up from about 300 images stacked etc in Registax, nothing fancy!

Thanks guy's! Here's another one showing the region around Clavius and Tycho. I was quite
pleased to get so much detail on the floor of Clavius as this can sometimes be difficult due to
seeing conditions. On this night the atmosphere was very steady.

That's a fabulous shot John, but I'm looking at it being a bit confused! I realise it's South at the top, but is it E/W reversed too? The oval crater towards the top left looks like Schiller hence suggests we're looking at a waning gibbous Moon - is that right?

Of course Paul I should have put it up with north up as the view through different scopes are different.
In the ETX90 east and west are reversed. Here is the more conventional view as one would see it in the sky.

Ah yes, that looks much more familiar! I still get confused with orientations myself as I have 3 Newtonians, 2 Maks and a 2 Refractors in the armoury!
