Alternative Views of the Mare Orientale Impact Basin. Lunar Orbit 1967 & Planet Earth 2021-02-27

I hope NASA are OK with their image from 1967 superimposed on my observation from planet Earth almost 54 years later.

 

This feature is not easily visible for earthbound observers at the best of times. Even then, only the eastern edges of this impact basin can be seen when there is a favourable libration. Most of it is consigned to the far side, out of sight for those who reside on our blue world.

 

 

My observation is a six pane mosaic of the lunar western limb captured on 27th February 2021 between 01:45 UT & 01:59 UT.

4000 frames captured on each pane using Firecapture.

 

Approx. 1400 to 1600 frames processed with Registax 6 on each pane.

 

Final image stitched with Microsoft ICE. Slight adjustment to levels, collage & annotations added using G.I.M.P.

 

Best viewed using the expansion arrows.

 

Some of the features are identified on another posting found in my album, Astronomical Observations Logbook.
