It was a just
another mad summers evening. The day after midsummers night. Two brave amateur
astronomers decide to drive a 50 mile round trip to climb up to the 850 foot
high summit of Beacon Hill. The challenge...if climbing up the hill in 27
degrees Celsius was not enough, was to carry 2 pairs of binoculars, 1 seat, 1
rucksack stuffed full of water bottles, a hand-held GPS, eyepieces and other
goodies, a 5" reflector and its base along with the heavy counterbalance
weights. Oh and to get up the hill before 3 of the 4 planets set at 10:15pm and
the Moon at it's largest since 1987 rises!
We arrive late due to a talkative
builder holding me up at my house. It is 10pm. The Sun has set. The light is
slowly fading. We load up like 2 mules for the trek up. As we ascend Jupiter
sits like the star of Bethlehem at the top of the hill. We race off with a fast
walking pace hoping to get to the top to catch the planets.
After the 370 foot trek to the top we
arrive to be confronted by a gorgeous red sunset and Venus shining bright quiet
high above the horizon. I shove the scopes tripod into the ground as Brendan
collapses into a chair to catch his breath. We both realise that we had
calculated the planets setting time based on typical horizons. What we have from
this height is the best horizons possible for almost a 360 degrees panoramic
view. It's 10:15pm and the planets did not set for at least another 30 minutes
so we catch our breaths.
We unpack our bins and easily capture
Venus in the lenses. Sweeping down to the West and into the red glow of the
atmosphere we see Mercury twinkling like a star. Moving up towards the South we
see a tiny spec...this is Saturn. No longer discernible as the ringed planet, it
now resides at some 1.5 billion km from the Earth and moving away fast. The last
time I looked at Saturn in the spring it was much bigger being some 300 million
miles closer.
As we setup the scope (which is
buffeted by a slight cool wind) and view these wondrous jewels in the sky, 4
teenagers arrive and with interest to share the views through the scope of these
planets. Amongst sounds of 'wow' and 'cool' we move from Mercury setting fast
now to Venus then to Saturn which we can barely make out the rings on, even at
180x magnification. We show them Jupiter, 3 of its moons easily visible, Io and
Ganymede off to the left as seen in my scope and Europa to the right. My young
keen eyes spot Callisto just at the bottom so close that I am not sure it is
really there. The two distinct cloud bands stretch across Jupiter's massive
girth.
We look up and Venus is gone,
disappeared into the mirky red atmosphere on the Western horizon. A shout from
behind me and Brendan "The Moon Man" spots the large red Moon slowly creeping up
from the East, it looks bloated, it looks like the Sun setting.......
Through the bins you notice the eerie
clouds that wrap around it's waist, the red moon crystal clear due to lack of
heat from the ground. We are looking across miles of fields with no sign of
towns in the way. This makes the air extremely still and the viewing fantastic!
We point the scope with the 40mm
eyepiece at the Moon and everyone quietly soaks up the view. The only
disturbance...mobile phones ringing, friends asking what the teenagers are up
to, in reply "were up on Beacon with a couple of guys and their cool telescope
and binoculars looking at planets and the Moon......". To me the Moon has never
looked so good, a painting on the sky.
As the Moon rises so it's apparent
size shrinks, less atmosphere to distort it and no frame of reference as we had
near the horizon. The teenagers say their goodbyes, one of them says "I'm going
to tell my parents how good this was and that I want to get my telescope back
out of the loft". Brendan and I are left on top of this now dark hill. In the
quiet darkness, we enjoy the views of the stars through the unpolluted skies.
Just before we pack up I am sitting
looking West. I shout across to Brendan to look at the sky, after realising
where I am pointing he turns around and as if to place the 'icing on the cake'
of this great evening there hanging in the upper atmosphere the wispy filaments
of Noctilucent clouds. Forming some 50 miles above the Earths surface and some
ten times higher than cirrus clouds in an area of the atmosphere called the
mesopause, these clouds are tiny ice crystals and they shine like illuminated
cotton wool and are truly remarkable!
So after much gazing we decide to
pack up. The temperature is now 20 degrees Celsius and I am cold in shorts and a
vest. Dreaming of the hedge back at Cliddesden to keep us out of the wind, we
head off back down the hill dropping the 370 feet back to the car. On the way
Brendan comments "this would be a great place for a star party....." and I have
to agree!
