Moon composite reworked

On or about 2006-03-07,
Pete Lawrence illuminated us with:

Ok - revised dates now shown on the composite as well as another field
star that I'd inadvetantly masked off. I only noticed it when checking
the originals. I hope that TYC2-1154-1 doesn't have a planetary system
that bears a grudge ;-)

A level of excellence way beyond anything I might ever hope to achieve as
always! Maybe it's my old eyes, but is there something not quite right along
the bottom near where the terminator reaches the perimiter. It doesn't look
quite correctly round. Hmm, jiggling around a bit in the Gimp seems to
indicate a definate apparent change in radius around the 7:30 area. Or the
6:00 area. Or something. I'll go crawl back under my rock now.

The solution was to cheat! Basically, the problem getting the
composition of crescent and Earthshine right was to deal with the
terminator properly. This is virtually impossible because the two
images don't actually fit together due to over-exposure. The way
around this is to take an Earthshine image on one night and the
crescent image on the subsequent night. When these images are merged
together (e.g. using Photoshop's lighten layer blend) the overlap
removes the terminator issues resulting in a much more aesthetically
pelasing result. Well I got excited about it anyway ;-)

Pete,

There was a very impressive effort on LPOD (Lunar Photo of the Day)
about two years ago which made a great impression on me. Take a peek at
the following:

There's a new one on there today ;-)

Looking at the position of the star just off the limb in the
Earthshine image and in the composite, I think I sent the wrong
Earthshine version over. I must admit that in a moment of tiredness I
didn't label the layers in the composite like I would normally. The
trouble with digital is that you can end up with a whole host of
images that all look very similar! Ho hum!

Amateur!

(hehe)

Here's how you really cheat this kind of image:

ISTR this was a composite of a 7-day-old and a 20-day-old moon.
(No earthshine, y'see)

Taken about 6 years ago.

(...and its not upside down - youse folk are.)

Cheers
