Log Entry for November 2014.
Since the beginning of November it has been slim pickings astronomy wise from here in Pembrokeshire.
So few have been the clear nights, that one sticks out in my mind - it was the first week of November.
The best night in November was the night of the 7th .
I decided to concentrate
on some Messier objects and put the Celestron through it’s paces.
Celestron C8 SCT |
M57 was glorious, it shone brightly with averted vision.
My 20mm Erfle eyepiece did a grand job of teasing out the photons.
M13 in Hercules was easy to locate in the finder scope.
The Erfle ep really revealed a lot of detail, a beautiful sparkling globular.
I trained the finderscope onto nearby M92, a vague hint of it could be detected.
The Erfle revealed a beautiful sparkling globular, not as big as
M13, but well worth spending time
observing.
M31 The Andromeda Galaxy was a magnificent sight high up above,
near the top of the sky.
Nearby companions NGC 205 (or M110 if you prefer, I
prefer NGC 205) and M32 were easy to
locate.
The last time I saw M32 that clearly I was peeping at it through a 6
inch refractor.
To test the seeing, and to give the Celestron a
challenge I trained it towards Epsilon Lyrae, the double double. Both
stars revealed their companions easily.
Albireo in nearby Cygnus delivered a striking Yellow primary
with a lapis lazuli blue.
I’m glad Albireo was on top form tonight, these past
several months this most favourite of stars was noticeably washed out, until
tonight I was blaming the lack of colour on my ageing eye.
Thankfully
tonight the clear skies restored faith in my eyesight.
Gamma Delphinus had to go and spoil it though by returning a lack lustre green and yellow,
not the bright lemon and lime colours usually detected.
I reckon the skyglow
of Milford Haven might be the culprit
for lack of detail in this most beautiful of double stars.
At midnight I began
turning my eye towards Jupiter who by now was well above the roof tops and
some distance away from the blessed trees of my next door neighbour.

By chance I witnessed the emergence of Europa from behind
the gas giant, plus at the same time a transit of Ganymede was also in progress.
It was complete luck that I happened to witness
Europa emerging from behind the gas giant.
The satellites of Jupiter are a source of constant
fascination, though I do have some trouble teasing out the details in the
belts.
This I know is in a large part due to the seeing conditions from my
location.
The Celestron performed really well, though the mirror image
of the planet is a bit strange, though I will undoubtedly become accustomed to
it!
That dance of Europa
and Ganymede was a beautiful grande
finale to the evenings viewing.

Returning Subaru echoes the Autumn.
Glitter like a swarm of fireflies
Tangled in a silver braid
Tennyson
A clear night with a whisper of a cooling breeze.
High up Vega is now noticeably Westward
bound.
The Pleiades now spotted in the East.. here
comes the Autumn.
There are many names given to this most
wonderful of star clusters, The Seven Sisters, The Starry Seven, Children of
Atlas, The Seven Atlantic Sisters, The Hen and her Chicks to name just a few.
But my favourite name for the Pleiades has
to be the Japanese name of SUBARU.
The Japanese language contains some lovely
astronomy related names e.g. Hoshi=Star, Hi=Sun, Tsuki=Moon, Milky
Way=Ama-No-Gawa.
Viewing Subaru through 8x40 binoculars
never fails to bring a smile to my face.
This cluster was made for binoculars.
Subaru along with the Orion nebula can always guarantee a spontaneous WOW! followed by a dance around the garden.

A Swift view of the Milky Way.
This evening’s sky was a delight , even with the nearby streetlights shining, the Milky Way stretched far and wide overhead.
At about 11.00pm I grabbed my Swift 8x40 binoculars and planted myself in the front garden.
Thanks to an earlier collimation my new binoculars were spilling out sharp pin-point stars in all directions.
My Swift Auburon 8x40’s cost £15 at a local
bootsale, and I can highly recommend that particular model.
One thing is to always make sure that any
prospective binoculars have collimation grub screws.
These four tiny screws are easy to find (with
a magnifying glass!) and are necessary to properly align the stereo view you see.
Without the ability to adjust this double view, you will quickly go cross-eyed and relegate the binos to the dustbin!
For astronomy usage I would never
buy binoculars unless they have the four adjustment grub screws.
When I first tested the 8x40’s, I mounted
them on a tripod and placed Arcturus in the field of view.
I was rewarded with
a lovely view of Arcturus and what appeared to be its identical twin!
After a slight adjustment of all four grub
screws, the double image of Arcturus merged back into one sharp starlight
point.
Do they work?
Most definitely, so far I’ve had good
views of M13, M33, M31, M81/82, Kembles
Cascade, the Sword Handle and The Coat Hanger.
Plus, ambling through the river of the
Milky Way is a joy with those little 8x40’s.

Gibbous Moon and Chasing the ISS
This evening I took the Schmidt outside to spy the gibbous moon.
I wanted to have a good look at the Moon Maiden and Gassendi before they slipped behind the trees at the end of the garden.
After about ten minutes of viewing the moon slowly but surely slipped behind the blasted trees.
Never mind.... across I went to my favourite double Albireo.
With the 20mm Erfle in place I was able to distinguish the blue and yellow of this lovely double.
By defocusing the image the two stars exhibited an even stronger yellow and blue colour contrast.

Chasing the ISS
THEN.. in the west I noticed the International Space Station racing towards me.
I wondered if I would be able to capture its image in the Schmidt?
After a bit of frantic repositioning I centred the ISS in the field of view.. for about a SECOND!
I quickly tried to manually keep up with the ISS.
For several seconds I managed to see a decent image of what looked like two long horizontal bright bars, connected to a much shorter vertical bright bar.
Did I see the space station, or was my brain playing tricks with me?
I'm not sure, but at least what I saw was not the usual star like point of light, as seen through my binoculars.
