I had planned to start imaging around 21:30. I think Mars is at about 40° above the horizon by then. I think. It may be a bit lower. I’m going from visual observation (memory) the other night when I got called out. Dave On Apr 28, 2014, at 9:21, Chuck Hards <chuck.hards@gmail.com> wrote:
You may be better off waiting until Mars is higher. The sunset suggestion was mostly for the July 5th event Kelly posted about.
I've used both my hard-drive camcorder and the DSLR for video, both seem to produce the similar results on the moon, sun, and planets. It's the stacking and post-processing that gleans all the details.

Thanks for the information Chuck. I do have a little video camera. I’ll try imaging right after Sun goes down on Thursday.

One thing to note about observing right after sunset.
There is often a window lasting anywhere from five minutes to as long as 40 minutes, right after sunset, when the air is remarkably still and seeing is excellent. The sky is still blue, so you can't look at any faint fuzzies, but lunar and planetary observations are possible.
Apparently the ground hasn't begun to give up the heat it accumulated during the day yet. Sometimes this window doesn't appear, but often in summer it is there, briefly.
I took advantage of it when observing the Shoemaker-Levy 9 impacts on Jupiter. I got some incredibly good views for up to 40 minutes after sunset, before the air started boiling and seeing went downhill until well after midnight. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy
