Hello guys,

since here the weather keeps pn teasing us with exceptional transparency, but dreadful seeing, last night I collected some images only to create a mosaic of the whole moon. I had to use the 4" Tak at F8 since 800mm was the longest focal that I was able to use to beat the worst seeing I've ever seen on a clear night :C

For this reason the mosaic isn't very interesting, but it was obtained with four shots and I believe I'm beginning to get the gist of this "mosaic-ing" with PS.
Size reduced to 80%. Camera is Lumenera Infinity 2-1; each section is a stack of 10 frames out of 50.

Ciao all

Luca

Hi Luca -

I think it's a fine mosaic. I have made a number of full disk lunar images and I am always trying to make one a little better than the last. I thought the image a little dark overall perhaps the histogram can be stretched some?

best,
Alan

Thanks Paolo and Alan grin

I'll try to tweak the Histogram a bit, when I come back from dinner (social stuff: I couldn't care less with the sky clear and the Olympics on tv. But I've a lovely wife who puts up with me, so I must put up with her sometimes :S )


Ciao
