This is the 3rd panel from the 18th, encompassing the south polar region and the southern terminator, including Clavius, Tycho, Rupes Recta, and a host of features too numerous to name. Mare Nubium has some fantastic colors and is one of the top reasons I prefer to image in color

 

1100 EdgeHD + ASI183MC. about 2100 out of 3200 frames stacked. This is a thumbnail; you can click it to see the full resolution image on AstroBin.

 

 

 

 

Some full scale crops will follow.

Clavius & Tycho, with Blancanus half shadowed and very long shadows nearly blanketing Scheiner.

The colorful Mare Nubium, Rupes Recta, Arzachel with its interesting floor, and Alpetragius with its central dome.

 

[Borodog]

Trying to decide where to crop is hard. Here's Rupes Recta again, this time framed with Pitatus on the lower left, also with very interesting topology, and Werner on the right, with its bright white "pinhole" craterlet.

 

 

 

Thanks for looking. Any feedback is always welcomed.

Excellent images, you must have had great seeing while recording the video data these images were stacked from. They almost look like they were obtained from lunar orbit.

I forgot some of those smaller features. Thanks for reminding me with such great images.

Mike, this looks fantastic.  The sharpening is perfect......great details without artifacts.  Some residual noise that could probably be reduced, but I don't mind that, and the result looks very photographic.  I assume you are still using the "blind deconvolution"?  If so, my concern with this method is it appears to be hit and miss.  Sometimes the result seems like the perfect fit (such as here), although other times the sharpening is too much IMO and creates a result of lesser quality than we see here.  In those cases, some manual adjustments may be needed.  IMO opinion the level of detail and contrast in this image should be your "gold standard" to try and recreate each time.

Thanks, Achernar, 12BH7, and Tom.

 

Tom; yes, I am still using blind deconvolution. It's like any other sharpening method in that it produces better results with better data and more of it. When the seeing is good and I am able to stack thousands of frames, the results are better than when the seeing is poor and I can only stack a few hundred frames. It's no fault of David's software. Any misuse is entirely my own. :O)

 

Regarding denoise, I try to avoid it on lunar images unless absolutely required by being forced to stack too few frames for an image. I will always take noise for sharpness, even if it is only the appearance of sharpness due to noise. ;O) This is particularly so because I am only sharpening luminance these days, which does not bring up color noise, and luminance noise at the pixel level gives the image a grittiness or texture that I like. There was no denoise used on this image at all.

Spectacular stuff Mike.  Likely your best ever.  Something to shoot for IF the clouds and Lunar phases will align for me!!

Thank you very much, Don. Much appreciated.

Hello Mike,

 

these are truly exceptional captures, especially when viewed in the full resolution on Astrobin!

 

Thank you so much for sharing,

Hi Mike,

             No problem in giving praise when it is due. I have my telescopes out of use at the moment as we have moved house and are waiting for our new house to be built. Boy, do I miss being able to go out and view the heavens. Hopefully it will only be for this year, we expect to be settled in our new home (God willing) by November. Still I can visit our moon by coming to cloudy nights and viewing the amazing images fellow amateur astronomers share with each other. Keep well and enjoy the wonders of creation. Larry
