A Lunar Crime

[astroavani]

Spending hours capturing, then a few more hours to process, when it's almost over to find out that a few pieces were missing due to misalignment, is what I call a real crime.
179 Mb mosaic from 36 frames, stacking 185 frames per movie from a total of 1200 frames in each movie.
AS! 2 + Irtan + iMerge Processing
Image reduced to 5000 X 5000 pixel.
Despite this novice mistake, I chose to post the image and thus make it clear to my colleagues that we must be very careful not to lose a few dozen hours of work.

What's there looks like an absolutely excellent image :)  The detail in the crater rays on the lit side and the craters themselves near the terminator is lovely.

Having bits missing from a lunar mosaic is almost a requirement though.  All the best people do it.  You've not done a proper lunar mosaic until you have one with bits missing :D

Yeah, I like it too. It looks like those NASA images, very "scientific" look. 😀

Very nice image, as always Avani!

That is a beauty. Real shame about the missing parts

There's a glitch in the Matrix but, otherwise, it is a beautiful image!

No crime here, other than making me jealous of the level detail in the rest of the image 🙂

It's a pity about the uncharted territory, but most of the disk is there and it's awesome!

That is a stunning image of the moon. The level of detail is unbelievable 🙂

What area of the moon is named the terminator? I have heard this term a few times now but do not know the location?

Thanks in advance.

The terminator is the line across the surface of the Moon between light and dark, the edge of the sunlight falling on the surface. It moves with the changing phase of the Moon. It is the area where the strongest shadows are cast by features of the lunar surface, giving the best sense of depth.

As for this lunar montage - nice idea to post the not so successful images too. It is properly frustrating when the stitch comes back with the dreaded black holes!

Thank you Gav, That information is much appreciated. So in the above image would I be right in saying the terminator is on the right side from approximately 12 to 6 o'clock as the craters here are showing the most features.

 

Thanks

Exactly, the terminator is the right hand edge of this 90 something % waning Gibbous Moon. You can certainly see stunning detail in this amazing image! (Despite the black holes)

This will help explain it.

Excellent, You learn something new everyday 🙂 

Certainly the right hand "edge" rather than side as I have described.

 

Thanks you

Lovely image Avani!

@Barry-W-Fenner one interesting comparison I saw up on SGL was an image of the Moon at part phase, alongside an image of it partially eclipsed to the same degree. This really shows the difference in illumination angle. At normal phase you get the terminator, when eclipsed, the light is coming from straight above so the is no terminator as such, just a softer transition from light to dark. I'll try to find it and post a link.

That would be great, I would like to see that pic Stu to get a better understanding of the terminator effect! 🙂
