This was my first night using my new (used) Orion Atlas mount.  Wow it's beefy!  I took a bit to set it up, but when it was it was sweet!  What have I been doing for the past year with that ancient LX10 fork mount?  I let it run for a couple hours while I went in to sleep for a bit (so moon higher in sky), but when I came out the hand controller for the mount was toasted.  Drat.  I still managed to snap off enough shots to make a nice mosaic though.  Note the large amount of libration when you compare this image to the one from Feb. 24th below.

Had left setup out from previous night since forecast was for a couple nice days in a row.  Got up at 3am again to image the Moon.  Since still without replacement EQDIR, ran hand controller and laptop cables into stairwell at back door.  That way I could sit down and not be in the cold while I did the is February after all!  I got through all the f/3.3 shots and started the f/10 shots when thin high altitude clouds started to move in.

  • backyard, Ottawa, Canada

  • terminator ~ 9 E

Mount was still setup from several nights before.  Got up at 4am, ready to image by 4:30 but Moon still too low to see above trees and houses.  Had to wait until 5am to start imaging, finishing around 6:40.  The sky was starting to lighten but image contrast was still good up until I was finished.  I think my collimation and focus was very good tonight as Cassini and Vallis Alpes looked very crisp.
