Mosaicing the moon

Having proved the camera works well on the moon, finally a clear night (and I mean properly clear), the first in 6 weeks, and I got the little Mak out for an attempt on a full lunar mosaic. Being full moon of course meant lots of segments. Anyway... A quick PA, balance, find the moon, focus and test and I was off. I drove the mount with EQMOD and used the game controller to move around the moon. I used VirtualDUB to check each AVI for alignment and to ensure I didn't miss any bits, I left plenty of overlap. I captured 34 sections. I probably didn't need that many, I actually only used 33 in the final mosaic. After stacking each 500 frame avi in Registax, I put the output into imerge and aligned as I went along. I also captured a few images with the Ultima x2 barlow, for a short string along the terminator and a single image of Bailly. I did try stacking the 2 x2 barlows, and using the x5 barlow. The seeing was not up to this, there were times, I wasn't even sure the seeing was up to imaging without a barlow but it worked out ok.

Anyway, here's the results.

Bailly


The edge, this is a 5 pane mosaic


And the full disk mosaic, 33 pane mosaic.


Click for bigger. I enjoyed and needed that, although it was very cold.
