This is a combination of 5 x 30 second exposures of Cassiopeia.
taken with a Canon digital SLR camera, stacked using Deep
sky stacker to remove noise and increase detail.
The image, taken by Trevor O'Donaghue, is centered on the constellation
and shows the Andromeda galaxy (just above center on the right)
and the double cluster (lower center) nearly lost in the band
of the Milky Way.
Partial lunar eclipse.
There was a penumbral lunar eclipse on the night of the 18th
of October. Although, even at its peak, (at 00:50 BST) only 76%
of the moon lay inside the penumbral shadow.
This made it very difficult to notice but with the camera, the
Southern limb (at the five o'clock position on the picture opposite)
is a little darker than usual.

Venus in the autumn evening skies.
Venus has returned to our evening skies. On the 1st of November
it is at greatest eastern elongation from the Sun. This evening
pass of Venus never sees it very high above the south-westeren
horizon and as the month progresses it beggins its journey back
to align with the Sun.
As it does it climbs from the horizon and gets closer to Earth.
There fore even though the percentage illuminated decreases its
angular size increases and with it its brightness.
At start of the month, it sets at 18:25 and by month's end at
18:40. It is in Sagittarius and brightens from mag -4.5 to mag
-4.8 during the month.
Close pass of Asteroid 2012 DA14, Feb. 15th 2013.
On the evening of the close pass of this asteroid, several club
members were lucky enough to have a clearing sky to enable us
attempt to see this asteroid pass by.
At magnitude 7, and fading rapidly as the ~50m body receded
from us, it was never going to be an easy target. To put it in
perspective we were trying to see a medium size building from
30+ thousand km!
Despise scanning good clear skies with various size binoculars,
none of us saw it visually.
However Pat Granfield did his homework and had several transit
positions, at various times, programmed into his polar mount and
with his Meade, he succeeded in capturing it in a couple of these
The frames opposite were best centered and with the least cloud
A great achievement, well done Pat.

Global Astronomy month observing session 27th of April 2012.
On the evening of April 27th we held an observing session at
Carpark No.2 in Banna Beach. We had a nice crescent Moon, Venus,
Mars and Saturn as well as the beginning of the summer constellations
on view. In the image here Betelgeuse in Orion is just visible
to the right of the tripod above the sand dunes.
Venus was a thinning crescent in the telescope as it continued
its swing back toward the Sun for its transit on the 6th of June
2012. The image over shows it just below Auriga in the constellation
The Moon was just over 30% illuminated but was still bright enough
to limit any deep sky observing. In the north near the terminator
were the remarkable craters of Eudoxus and Aristoteles while in
the South, Maurolycus and Clairaut were even more so.
Mars was nice and high in Leo but gave up very little detail
and had noticeable shrunk in apparent size since our last viewing.
Saturn was stunning with it's rings well open again and four
of its Moons, Titan, Tethys, Rhea and Dione all visible. The Cassini
division was only occasionally spotted when the air steadied.
The International Space Station (ISS) is visible
from Ireland in the Evening and Morning Sky for at different times
throughout the year. Check the links below for times.
The times are available here for when it is visible
