Subject: Re: [Astro_IIDC] Moon Anaglyph


I was involved briefly with a Luna 3D project a couple of years ago where we were trying to coordinate photographers in both hemispheres to make simultaneous photos of a feature, using the Earth's diameter as a baseline. IIRC, we were never able to coordinate dates and weather.


The other problem was that the eastern photographer had to shoot early in the morning.  If I were going to try again, I'd try to coordinate two cameras, one in S. Africa and the other in eastern Europe (around 20°E for both, 30°S & 50°N).


One thing to try for a single observer would be to use libration to create your baseline. I'd need to do more research to determine two nights with the moon at the same age (within several hours at least) and opposite librations (if that's the word).

Hi Alberto,


Thanks for the interesting project idea. 


I am afraid if I ever experienced six hours of good seeing, I will be flying with a harp in heaven! But I will keep it in mind should I encounter such a fine night on earth.


best wishes,

Alan

Hello to all,

i recently added 2 files in the Lunar section.

One of them is an anaglyph to be watched with red/cyan 3D glasses:


Anaglyph-SouthPole 3000x2000.jpg 



I! 'm wondering about doing some anaglyph starting from high-end quality images like Alan Friedman ones... :-)

Maybe Alan could kindly take a wonderful detail (like the delicious Plato or Copernicus i can see on his site ) 3 hours before the meridian transit and 3 hours after that transit....pleeease!!

I guess  that 6 hours-difference  could be enough to reveal the internal 3d structures of the craters but i'm not sure of that.

The sine-qua-non condition is to have the very best image quality and the most similar settings (exposure, contrast etc) for the 2 images.


I attempted to get single craters images but my quality was not enough even because i found bad seeing in almost one of the 2 shots (yes you need 6 hours of good seeing).



The other file added is a Moon mosaic grabbed with my C8. 

I printed a 70x100 cm poster of it:

080214-The Moon 6353 x 4326.jpg 



kind regards to all


Alberto


PS: i did some experiment with DMK on well known DSO (M51) not guided: really interesting results.
