Good work Richard! I can't wait for these series of storms to pass through here, in the East; and for the air to warm up, somewhat; so I can end this vicarious viewing of the Moon through the fine pictures produced by yourself, Mike, and others.

Interesting area to observe, I'll have to look it up on the moon map. Think I saw these the other night but did not know the names. Was this from the last few nights?

Great images BTW!

Rich my fab is the detail in the Messier craters and Petavius' topography. It's got a high angle if illumination but the success in the image is that you've gotten enough contrast that the sculptural quality is still presenting a convincing 3d impression. A lesser image would have it appearing flat. The others are great but those are my favorites. Bold of you to image the high and angle sunlit regions, but you walked off with the prize for your efforts. You be got a winner setup.

Pete

Ps: langrenus is superb too but I've always liked Petavius " road to the central city" spanning out like a radi to the craters edge.

Thanks for all the great comments! I love being in the company of fellow lunatics.

Here's a question for you...what's the name of the odd crater in this picture? It really jumped out at me last night.

It appears to be the crater Romer. The "o" is supposed to have 2 dots, not sure how to get that out of my keyboard...

Yes, it's crater Römer and Rimae Römer is adjacent to it.

And, those are very nice images!

Superb captures Richard, my fav is Posidonius! These are prime focus shots? I think you have your capture settings right on the money!

great stuff!

Yep, prime focus with the camera, but I think the camera produces effective magnification of a 7mm eyepiece or something. Not sure I will get much if I barlow from there. My tracking is still not good enough to capture the requisite frames at longer FL. Working on that, along with improving image processing. It an ongoing learning experience, but with great rewards (to me).

The most important thing I've learned in capturing thus far is to fill the histogram. Now if I could understand the dynamics of gain, various formats, pixel design, etc. I have resisted moving to a filter wheel until I can improve my tracking enough for the sequential captures, but not sure this applies much to lunar.

Bottom line is I love it and have a supportive spouse.

Then you are truly blessed, Richard. The latter enhances the viewing experience and puts more into one's step during daylight hours, as well.

Indeed. I have had the other kind, but found my way at last.

Great shots! I love Posidonius - that's a whacky crater! Cool stitching pattern inside the crater, looks like a big number '5'.
