Not many large telescopes in permanent observatories actually have
eyepieces attached to the business end of the scope. Most have CCD cameras
or other instrument packages attached, and viewing is done remotely at a
computer monitor.

At Stamford Observatory the 22" Gregory Maksutov has a whole turret of
eyepieces for the observer to select from. For two nights in November last
year, I had the privilege of observing with the big scope at Stamford, the
old fashioned way, through the eyepiece.

I had been invited by Charles Scovil, the observatory director, to come
visit him and observe at Stamford. So on Sunday, after the AAVSO fall
meeting in Cambridge, I found myself tailgating Chaz and his other guest,
Marc Beismans, across the countryside from Boston to Stamford.

We arrived at the observatory around dusk. Chaz gave Marc and me a tour
of the facility and then marched us up the stairs to the dome.

 I had seen pictures of the telescope
before, but I wasn't prepared for the
sight of the 22" up close when the
lights were flipped on. It's massive!
The solid tube, painted silver, adorned
with a number of guide-scopes, finder-
scopes and the eyepiece turret, looks
like a giant cannon out of some Buck
Rogers fantasy. I was also surprised at
the thickness and extreme curvature
of the meniscus, and the relatively
small size of the secondary.
 
  The control panel has digital setting circles,
a joystick for telescope control, controls
for rotating the dome and a switch for
pumping oil into the bearing of the huge
fork mount. The telescope makes a slow,
rhythmic squeaking sound when the drive
is engaged. A sound I never did get
completely comfortable with.
 
 

  In spite of hazy skies and a nearly full moon, we took turns observing at
the eyepiece of the 22. We observed a fading nova, V2275 Cyg, and RX Lyr,
an LPV Chaz and Marc were working on new charts for. This is an interesting
star if for no other reason than the ghostly smoke ring, M57, resides in
the same medium power field.

 
  One of the things I had looked forward to was making positive
observations of some of my program CVs at minimum. Observations that are
usually difficult or impossible in my 10" scope. As luck would have it SS
Aur, U Gem, KT Per and TZ Per, four of my intended targets, all went into
outburst during my visit! Just as well, since sky conditions favored
brighter objects that first night.
 
  Skies deteriorated quickly, so we closed up the dome and went to dinner,
hoping for a change in local conditions. It rained while we were eating and
never did improve that night, so we spent the rest of the morning in the
inner sanctum of chart making for the AAVSO, Charles' office on the second
floor of the observatory.
 
  Monday evening looked very promising as I pulled up to the observatory.
The skies had begun to clear and I could almost smell the Canadian high
pressure that is my best friend back home in Michigan.
 
  Charles and Marc were already there and had opened the dome and readied
the scope for another night of observing. Unfortunately, Charles had other
plans for the night and asked if I would mind observing alone, since he and
Marc were busy preparing the new charts for RX Lyr.
 
  I tried not to giggle as I found myself saying, "No, I won't mind having
this huge telescope to myself all night!"
 
  It happened to be my birthday, and I couldn't have dreamed of a better
gift. At least that was what I thought at the time.
 
  After a couple hours of being blissfully absorbed in observing in
Andromeda and Perseus, I suddenly began having trouble seeing faint stars.
I thought maybe it was time to take a break or that the weather had taken a
turn when I looked out the dome slot and the sky appeared orange. Or was
that red?
 
  It quickly dawned on me as I ran out on to the observation deck that Chaz
had ordered up one of the most dramatic auroral displays I had ever
witnessed in honor of my birthday! We all stood outside under the blazing
red, orange and green lights for a long time.
 
  In spite of the moon and occasional auroral flare-ups later that night, I
was able to log several 16th magnitude observations. The faintest positive
observation was in one of my favorite fields in Auriga, ST Aur. I was able
to see it at or near minimum at 15.7. After making an estimate of RX And in
outburst I scanned over M31, quite a sight in a 22" scope.
 
  At times it was necessary to re-align the digital circles on a bright
star. I was impressed by the different colors of these stars blazing in the
eyepiece of the 22" Mak. Betelgeuse, Aldeberan, Vega and Altair left
lasting impressions on my mind and dark adaptation!
 
  Closing up for the night felt strangely familiar as I capped the end of
the scope, parked it in the home position, closed the dome slot and turned
off the power. Of course, the cap for my scope looks like a Frisbee,
whereas the cap for the 22" is more the size of a garbage can lid!
 
I slept with a smile on my face that morning.
 
I hope to return some time soon (around new moon) and do it all again.
