Last night at the Peak, many of us were able to get good DSO viewing along with occasional detailed views of Mars. The 5-10 mph wind didn't cease until after midnight and Rich and I were concerned about setting up until the sun was setting at 8:30 pm.
We walked over to the observatory to see if the wind was less there, but it was not. By 10 pm, I looked at rising Mars and Antares 10 degs. up in the southeast. Both were boiling a lot. Then, I checked out a few close doubles at another location overhead to see how the turbulence was. It wasn't affecting the close doubles' there as much.
Epsilon Lyra showed nice clean stars with some diffraction at 231X. It was better located seeing wise and higher in the northeast. But, Antares and Mars were lower in the sky to the southeast and more importantly west of the Peak showed a lot of boiling. I believe the SW wind was being affected by the Peak as it went on the Mars and Antares leeward. Mars never gave any detail until it past the meridian at 12:30 am being a little west of the Peak. I think the westerly wind was affecting our view of Mars while it lie east of the Peak, being downwind up until that time.
Once Mars was west of the Peak, upwind of it, we were able to see sub-arcsec details on its surface occasionally. Syrtis M., Hellas, N. and S. polar caps, and much finer spots and gradations all came out now and then to give us the treat we were waiting for. Mars was too bright and glarey for my 10" Mak, so I used to bino-viewer with the prism attachment. This lower the light throughput somewhat and afforded me the better detailed views using two 10 mm Zeiss Abbe's, yielding 462X.
