River Astronomical Society and The Internation Sidewalk Astronomy Night
regularly scheduled ISANight was clouded out we chose tonight for the
We had a youth group from Lorain at the Observatory. Tim Kreja and Jim
Cunningham helped our guests
through the Nielson Observatory and offered them some spectacular views
of the Moon, Jupiter and Saturn
through the C-14.
Dave Lengyel and I
set up our scopes outside. Dave demonstarated a lo-tech setup using an
8" f/4.5 Dob
while I went for shock and awe with an "8 f/6.3 SCT and an 80mm F/5.0
on a goto mount. While observers
were looking through the 8" scope those waiting in line could watch the
video monitor which was caturing
video from the 80mm refractor.
The group was quite large but very well behaved, gracious and
attentive. We heard lots of "Oooohs and Aaaaahs."
In addition to the 30some students and the counselers, probably a
couple of dozen "Hams" stopped in also.
The NOARS Amateur Radio Club was celebrating their annual Field Day
event close by the Nielson
It never really got quite clear out. The upside of this was a lot
of ice crystals in the upper atmosphere. A small moondog
appeared and eventally became a full halo with a large spike. Here's
the money shot.............
After the "lightweights" went home Tim K and I set out to try and
capture some images through the C-14. We wanted
to see how well the new focal reducer worked for photographic work.
First, the clouds never did go away so we shot through them.
Second, there appears to be a problem with the C-14 drive.
Even at f/6.3 we could not get round stars.

The image (left) at f/6.3 doesn't look too awfully bad at low
magnification. However, zoom in and you can see the
stars are all trailed. The stars in the photo at right are
trailed even w/out magnification, resulting in a very poor image.
Here's Jupiter at f/6.3 and at F/10 with a 3x barlow
So, in summary, we had a great time......................
We introduced our hobby to today's youth, fullfilling our obligation to
The Sidewalk Astronomers and complying with our constitution.
We got to see an unusual transient astronomical event in the Moondog
And lastly we got spend some time under dark skies together.
Tim and I finally locked up and headed for home at about 3:00am.
I can't wait to do it again!
