FROM: History
of the Discovery of the Deep Sky Objects (SEDS)
"As a major milestone in
deepsky discovery, the Messier Catalog was published in its final version
of 103
objects in 1781 in the Connaissance des Temps
for 1784. Together with its more recent additions which
brought it to 110 entries, which at least all
but one (M102) belong to real objects (though four
of them were
missed for over a century), it contains the majority
of all clusters, nebulae, and galaxies known up to April,
1782 (when M107 was the last Messier object to
be discovered, by Pierre Mechain)."

I am using a Celestron CG-14
f/11, a7x50mm finderscope and a Telrad, with a 55mm (Gary Russell)
Plossl, 71 power, ~35', exclusively There
have been four fruitful sessions so far, I have located and
logged a total of 67 objects as of Sat. May
6, 2K, the last one being M102. There is some contention
about this object being bright enough to been
seen by Messier and his assistants. It is quite dim.
(More, later)

I started on the Longmont's Messier
Marathon Weekend on March 3/4, 2K at the
Pawnee
Prairie
Grasslands-
Cactus Flats site, east of Ault and west of Briggsdale. That first night

April 27/28, 2K
My Second search night was an
orientation night at Carter Lake Knolls, the night didn't start out as
a
Messier search, but with my new Telrad and
fairly clear skies, I hit 32 objects that night, 10 of which
were 'M's. Before sunset there was a Red Bi-Plane
doing somersaults and barrel-rools above the Lake
for about an hour and a half. Early
in the night, I showed some of the more interesting objects to the
campers next to me and around 10pm started
to get serious about logging 'M' objects.
Despite the the forest fire, north 18
miles, at Rist Canyon. The seeing cleared up quite well, especially
in the early hours of the morning.

Note: This session ended with the
last object being located at 3:06am. I tend to give up the night,
when my
eyes tear up, when looking through the eyepiece.
I found that this termination time is directly proportional to the
temperature. The warmer it is, the longer the
session lasts.
May 3/4, 2K
The Third night was back out at Pawnee again
and I logged 26 objects. This was a beautiful night, clear
and warm, little wind. Their were two others
observers out that night, Dan Laszlo-18" Obsession and

100's, Stiking
M26- 3:40am Dozen brighter stars ~15'diam, very loose conglomeration
It's now on to the Coma Berenices area, which
I am slightly dreading, since it is so clustered
with M's, in such a small area.
*********************************************************************************************
The Fourth session was pretty much hazed
out. It was hard to get any steam up to check for M's.
It was a great day, VERY clear, and then 1
1/2 hours after sunset in came this nasty line of
clouds that obscured the western 1/2 of the
sky and slowly degraded the rest of the sky over the
next hour or so.
Draco
M102 - 11:10pm
Edge-on spiral, no visible nuc. Ken VanLew also observe the
object.
*********************************************************************************************
I'm no longer talleying the sessions, this is the next one.
Story, Wyo. Sept.8, 2000 at the Scenic Turnaround, 4900' elev. , windy, clear, dark. Quite a bit of turbulence.
Pisces
M74- Spiral Galaxy, medium bright nucleus,
8' diam, 9th mag.
Sighted more objects, but had already located
them for my Messier search. 4:25 am Aurora
reared
it's spikey
little head and I took about 7 shots from 20sec-
1 minute. Something has got to turn up.
*********************************************************************************************
First Star Party at Virginia Dale ,
Sept 30/Oct1, 2K
At 34 miles north of the 'Y' at
north Ft. Collins and 7560 ft. elevation, near (15 foot) the Wyoming
border, 500 yards west of Hwy 287. V. Dale
is a excellent dark site with small light domes from
Ft. Collins-Denver and Cheyenne areas.
These were exasperated by a lower level cloud
layer, But did little to obfuscate the viewing. While
the stars Eta & Theta Scorpio were not
visible. I could see the rest of the Scorpion's tail. Setup at
about 500 yards from Hwy 287 there are two
Mercury street lights that are visible through trees if
you set up at the top of the ridge.
There is plenty of space lower on the slope. The atmosphere was
unsettled but transparent. The wind was slightly
breezy at sunset and picked up through 5am.
The night started out partly cloudy,
Venus was visible as a gibbous disk and the crescent
moon was glorious. I located M51
before twilight ended. After locating a few more of the brighter
objects waiting for dark, the owner showed
up with her 4.5" Newtonian. Being a beginning we went
through some of the brightest objects together,
M31/M33, Double Cluster in Perseus, Ring Nebula
in Lyra, double star Mizar/Alcor. M22 G.C.
in Sag., The Swan, etc.
From about midnight to 2:45 it was
completely overcast. After clearing up, Orion was as bright
as I have ever seen it. I swear I could see
'The Nebula'', 90' wide. The contrast was excellent and
I had no problem finding M50, 78, 35, 79,
41,46,47, 97, 108 and N2768, by star hopping. It was possible
to see M81/82 in the 7x50mm finder scope.
So with the twilight starting and the wind getting the better
of me, I packed it in .
As a first time report of V. Dale, I
would say, it can be dark, even very dark, if no clouds are present,
the contrast was GREAT, the wind does appear
to be more of a problem than at Pawnee. I will bring an
extra layer of clothes and something warm
to drink. It more or less the same distance as Pawnee for
those in Ft. Collins or coming from the south.
There are a few VERY short sloped sections on the 500
yard dirt road to the site from the highway,
but well worth the extra care. I think this will be an excellent
site weather willing and I'm really looking
forward to trying some astro-photography when the wind
doesn't intervene. As always these objects
were observed through a C-14 with a 55mm Russell Plossel.
M78- Orion Diffuse Nebula~5' Above belt stars
4:05 Oct. 1, 2000 (Prev.)
M79- Lepus G.C. 10' dim, below Orion 4:05am
(Prev.)
M46- Puppis O.C. 25' Dim w/ oval Planetary
Nebula at edge. 5:05am (Prev.)
M47 Puppis O.C. `20', but brighter than M46
35 brighter stars. 5:10am (Prev.)
getting there, 41 left!
