ALP February 22, 2009 Comet
C/2007 N3 Lulin Observation Report
by James Kevin Ty
After the conclusion of the National Astronomy Week
2009 Celebration with a free public stargazing session at Baywalk
last February 21, some
members of the Astronomical League of the Philippines (ALP) that
include ALP President James Kevin Ty, ALP VP Jett Aguilar, Vincent Lao,
Dennis Buenviaje and Andrew Ian Chan proceeded to PAGASA Observatory at
UP-Diliman to try to observe and image the brightening Comet C/2007 N3 Lulin
which was estimated to be around magnitude 6 that time.
James brought along his TV-101 refractor on
GP-DX mount while Jett setup his Takahashi TSA-102 refractor on GP-DX mount;
Andrew with his Skywatcher 80ED refractor on EQ-1 mount , Vincent with his
Orion 4.5" Orion Starblast Newtonian reflector on EQ-1 mount.
ALPer Andrew Ian Chan was on
bended knees because of the almost zenithal position
of the comet and observing it through his Skywatcher
80ED refractor on EQ-1 mount.
ALPer Vincent Lao was all
smiles as he was able to image the comet even with
his point and shoot digicam afocally attached to his
Orion 4.5" Starblast reflector on EQ-1 mount.
ALPer Dennis Buenviaje used a
pair of 10x50 binoculars to observe the comet.
PAGASA astronomer Rueben
Cunanan also used a pair of binoculars to observe
the comet with ALPers.

comet with his TV-101 refractor on GP-DX mount.
ALP VP Jett Aguilar was
finally able to image the comet amid early problems
encountered with his Takahashi TSA-102 refractor on
They arrived at the site at around 1:00 am.
Amid an earlier stargazing session at Baywalk, they were still able to
garner enough strength and persistence to try to locate the comet.
and Andrew were trying to locate the comet a day earlier at their place but
weren't lucky enough to find it due to light pollution sky in their
residences. James told them although the sky at PAGASA observatory is
not that dark as what they are accustomed in Caliraya, Laguna, he said that
it is still dark enough for them to locate it there. And true enough, after
around 30 minutes of locating the comet, they were able to find the comet!
James , Jett and Vincent hurriedly setup their cameras and tried to image
the comet as the comet was situated almost at the zenith that time.
The comet was bright enough to be seen even with a pair of binoculars as well
as through finderscopes. They were also able to detect a faint tail
that was about 1.0 deg long amid a light polluted sky . Jett got trouble
again with his imaging setup earlier that morning and was already calling it
a day but James still urged Jett to take his time and remedy the problem as
it was still early and he abided. After 30 minutes of fumbling his astro-imaging gears, he was all set to image the comet. Although the
sky was starting to brighten up a bit already, he was able to still image the
At around 4:30am, they posed for a traditional
group shop to end the session and quickly packed up their gears and head
home with a happy feeling that they were able to locate and image the comet!
