My List of Observed Comets:
The Evolution of a
Comet Hunter & Observer
Beginning with my 4 1/2 inch Bauch & Lomb newtonian ("Newton")
these are the telescopes that helped me observe the listed comets. My second
telescope, an 8 inch f/8 ("Wm Herschel") was constructed
with the help of the members of the Astronomical Society of Southern New
England. My third and finel telescope is the 10 inch, Meade "STARFINDER"
("J.
H. Metcalf with "Newton") .
It was not until about the time of 103PHartley
2 (1991) that I became an active member of the International Comet Quarterly,
and began understanding and using the terms and methods for observing and
reporting my comet observations. Having had experience with Variable Stars
and making estimates of their magnitudes, I had little trouble in that
area, and knowing the diameters of my lenses fields of view I had little
trouble there as well. It was estimating the "Degree of condensation",
or differentiating between the the central condensation and false nucleus,
that took some time to understand, as I found out later so had many other
observers.
Some Comet People I've Met or Speak
With
My Faverate Observing & Hunting Ground
:
When I lived in Rehoboth, Massachusetts,
not far from Taunton, my home was not far from this site bit I never knew
of it since at home I was able to pull my scope out from a small shed in
the backyard. After moving to Taunton I was forced to seek out a
new observing site. This field, I call "Bob's Field" is the closest
and darkest site within 20 minutes of home. The northern sky can
yield (with some work) naked-eye magnitudes of between 5.5 and 6.0.
The eastern horizon can yield down to about the same, as well as the southeast.
The south is not too bad granting 5th magnitude.
But the western horizon is not very good with Providence, Rhode Island
about 20 miles away.

Using 10x50s
To: 03/27/96
Comments: This comet was (in my opinion) a Great Comet. The
detail that I was able to resolve using the 10" f/4.5 and the 60cm f/400
was totally outstanding. Because of my moving to Taunton, Mass. observations
were greatly hindered. Slightly more than 34 obs. were made.
However, only the 34 were recorded. If all of the recorded observations
are not found in the index file, the rest will be located in the folder
file.

It's projected magnitude for 08/11/96 was between 9.5 and 9.9, my
estimate was 7.9, six observations were made. Maximum magnitude:7.8

Tabur
1996Q1 39
To: 11/11/96
Comments: (For historical data see Sky & Telescope, November
1996)
Three or four photographs taken of the comet during the using the
Pentex KM with a 135mm lens at f/4, exposures ranged from 1 minute, 1 1/2
minutes, 2 minutes, 3 minutes. October 5.30: 3 photographs taken using
270mm lens (135mm w/doubler) f/8 exposures were 2 minutes, 2 1/2 minutes
3 minutes.
This come had reached magnitude 5.5 earlier than predicted. Photographs
taken on 10/08/ 4:30 am, 270mm f/8: 2 minutes, 4 minutes, 6 minutes. October
12.31(3:38am/07:38UT); Eleven photos ASA400) taken of the comet having
a magnitude of 5.0, diam. 15'. Using a drive corrector trailing was still
a slight problem for many. Seven of the eleven were good.
Those using the 135mm at f/4 were best, 270mm at f/5.6 was under
exposed slightly. Need practice with corrector using 270mm. Attempted to
observe 1996Q1 on the evening of November 1st but the comet was not visible.
John Bortle reports through Sky-line that the comet has fizzled-down to
9th magnitude. The comet is only a couple days from perihelion. Although
this is not an unknown event as far as comets go, it is indeed a very rear
event!! Last observation made was on November 11,1996. No comet was observed
Maximum magnitude:5.0(10/18/1996)

POEM
To: 04/27/97
Comments: First observation was made on 01/08, while going to work
I stopped and took some photographs of it using my Pentex KM, with
a 135mm lens and ASA1000 film, 25 - 30 sec. exposure. Shots came out very
exposed because of the rising dawn, however, the comet did show of the
print. I estimated the magnitude to be 3.0 at that time. On 01/09 was my
first prepared observation using comparison stars and 10x50 binoculars.
I estimated the comet at that time to be magnitude 2.5. John Bortle estimated
3.0 The first telescopic observation was on 01/12/, Hale-Bopp at that time
was already showing sunward activity as small jets extended from the disk-type
nuclear region. During the morning of 01/19/, 8 to 10 exposures were taken
about 90 minutes before sunrise ...(02/03/) photos were developed yesterday
with others taken during yesterday morning (5:00-5:30), photos from 01/09
were good for no tracking. Photos from the morning of the 2nd were tracked
and came out beautiful. Used the crosshair lens from the 4.5" refl. Finder-scope.
