Preparing for remote imaging
As was mentioned earlier, we (SLAS) are going to try for another remote imaging session using the 2m on Maui the night of Friday the 22nd of this month. To help in planning I'd appreciate folks here double checking what I've come up with so far. As bad luck would have it by the time the 22nd rolls around we here in Utah will be suffering from Daylight Silly Time putting us an hour further from Maui. Meaning: LOCAL MDT Sun sets at Hilo at 1832 2232 Nautical twilight at 1919 2319 Astronomical dark at 1945 2345 At the start of astronomical dark 0730 RA will be crossing the meridian (I'm especially interested in knowing if I got that right). Ideally I'm guessing we should be looking for a target that is around 0900 RA so it would start the session 1.5 hours east of the meridian, transit in the middle of our session and end 1.5 hours west of the meridian. Of course there would happen to be a nearly full Moon that night at about 9 RA and +12 Dec so we'll need to stay away from that part of the sky. I did see that C/2012 S1 (ISON) will be up high and about an hour west of the meridian when astronomical dark falls. So it might be fun to get a quick image of it before turning to whatever real target(s) is/are chosen. All comments and suggestions greatly appreciated. patrick
I am just verifying that I am looking in the right area. The area being between Leo and Cancer? And the moon being in cancer on that night? Jamie Bradley On Mar 7, 2013 9:45 PM, "Patrick Wiggins" <paw@wirelessbeehive.com> wrote:
