Jay: ngc6441 is on my list of globulars but as I recall it required sitting in the dirt to get down to declination -37 with a 17.5" dob. This Glob is never more that 13 degrees off the deck and that gives an airmass of 4.5. That's 4.5 times the atmosphere as looking straight up at the zenith. I suspect the Grim telescope would loose much of it's aperture to the back wall of the observatory. I found the abstract article interesting. RR lyrae stars have been photographed winking on and off in m5 by amateurs though. http://observers.org/tac.mailing.list/2009/Jun/0120.html DT --- On Fri, 7/3/09, JayLEads <jayleads@gmail.com> wrote:
research into it (loving planetary nebulas).
What I found interests me, a lot. I know that even with the 14 inch truss dob I own I have no chance for viewing JaFu2. I am just wondering if the Grim out at SPOC could or has captured this object or someone else here has using a large aperture scope? I have seen NGC 6441 but my fear on the planetary is that it sits too low on the southern horizon to capture even with a large scope (looking through all the atmosphere and junk), though the first week of August or last week of July could be worth a shot.
