As AJ said we finally got a great night out after the moiston Gods were
unkind to us. AJ, Thad Robosson, Steve Perry and I Convoyed up arriving about
1815. Good thing we got there early as the site eventually filled up.
As twilight faded the observing began. Like AJ. I gave the night an 8 for
seeing and a 9 for transparency. I also calculated a limiting magnitude of
6.0 at the Zenith.
Over the course of the night I finished three constellations in the SAC 110
list: Cygnus, Draco and Lacerta. My new OIII filter paid for itself worth the
views of the Veil Nebula, Filamentary structure was visible in my 8" at 71x
throughout the entire length of both halves. This is truly an object that you
need to revisit again and again to truly see all that is there. The filter
also helped greatly on some of the planetaries I observed. The Cats Eye in
Draco showed a marked difference with and without the filter. With the filter
I noted it as very green in color, Without the filter it had more of a bluish
tint. The Blinking Planetary in Cygnus showed as a very sharp green point of
light. The color was equal to if not brighter green than Uranus (insert bad
pun here). The nebulosity extended well beyond the Green point to about 5"
diameter.
I also found Comet C/1999 T1 McNaught-Hartley which is now in Ursa Minor,
having passed though Draco. My Planetarium software (Skymap Pro v.7) listed
it as mag 11.9. Not so. I found it as a barley visible point of light using
averted vision. My estimate is that it was definitely dimmer than mag 14. I
also shot a few pictures. The first being Sagittarius & Milky way rising
through the trees and also Cygnus & the summer milky way.
Between my observations I enjoyed peeks through AJ's new scope as he went on
a messier binge. I also played compare the Galaxies with Tom Polakis as we
compared views of NGC 5907 & NGC 6503 in Draco. Both are very nice edge on
spirals elongated 10-1 and 8-1 respectively. Oddly NGC 6503 showed no real
difference in detail in the 20' compared to the 8," it was considerably
brighter though (DUH). Between all this telescoping I took the time to enjoy
the view using natures optics, my eyes. I can remember seeing the milky way
look this good only once before. The central bulge of our home galaxy was
readily apparent as was the dust lane we know as the great rift. To me a
required part of any good observing session is admiring the view with the
naked eye. I find it helps put the universe in perspective.
Overall I logged 12 new objects and revisited several other favorites. I had
planned on leaving around 0100, but the sky was just too good to let go, so I
stuck around till moonrise.
Now here's hoping next week is a s good
Clear Skies
