  by  James Kevin Ty


Last August 7, members of ALP held its monthly 050807-h.jpg (83786 bytes)meeting at the residence of colleague Rev. Alice Villa-Real. Members who were present on the meeting were James Kevin Ty, Allen Yu, Rich Pijuan, Dante Cruz, Lea Visaya, Jett  Aguilar, Hans Gideon Cerdenia, Angie Tan, Melisa Bata, Dante Noche, Nat Nat and son Kim Paredes , Joel Munoz, Edmund Rosales, John Lawrence Uy, Joey Grajeda, new ALP member Tommy Tan , and guests Kurt Reyes, Zaira Ledda , Joy Lao and nephew Tim Lao.

The meeting started at around 3:00pm with  Edmund Rosales gives and informative lecture on basic astronomy entitled "Celestial Navigation."  He touched from historical backgrounds on how ancient people were able to use the stars to navigate the seas as well as determine directions.  He also discussed on how to use different types of star maps, how to determine altitude using basic hand technique; vernal and autumnal equinox, etc.

Then, it was Allen Yu's turn to  give a book review on the book entitled "Companion to the Cosmos" by John Gribbin, the book is an astronomy dictionary with extended discussion and info on Cosmology and  Astrophysics..

Afterwards, James Kevin Ty then discussed on the computations of determining magnifications, actual field of view, difference between the standard 50 degrees eyepieces compared to the more expensive wide angles (60 degrees) , Panoptics (68 degrees) and Naglers (82 degrees) eyepieces and how they differ in terms of quality and field of view.  He also tackle a little way on how to select a good eyepiece set for a particular telescope in terms of determining its proportion to our eyes' exit pupil.  He mostly use the optical specifications of the ALP's 8" f/10 Schmidt-Cassegrain telescope as example so that it can be memorized by the members when using the telescope in stargazing as well as public viewing.

After the lecture, James also invited the members to join him to observe the August 14 Antares Occultation by the Moon at UP-PAGASA Observatory wherein they will share data with observatory staff headed by Elmor Escosia to get images as well as timing Ingress (Disappearance) and Egress (Reappearance) contact times.   The data will be forwarded to IOTA as well as ALPO afterwards.  He also gives some tips on what a occultation observers should need aside from the telescope such as stop watch, compass, GPS ( to get exact location data as well as accurate time signal)   video and still cameras , etc.

Lastly, the winners of the just concluded 1st ALP 050807-q.jpg (26758 bytes)9 ball tournament , held last July 31, 2005 at Playdium Bowling and Billiards Corporation at Araneta Ave, Quezon City, were awarded their trophies as well as P1000  cash prize for the champion.  James Kevin Ty was declared champion of the tournament followed by Allen Yu and Jonathan Alcartado as 1st and 2nd runner-ups respectively.  Jonathan was not around, so Joey Grajeda recieved the 2nd runner up trophy on behalf of him.   Dante Cruz, who was the billiard tournament official scorer presented the awards to them.  Congratulations to the winners!

The meeting ended at around 6pm already but our fellow ALPer Jett Aguilar hosted a big birthday blowout party at Hap Chan Tea House to the delight of the members who attended the meeting. Belated Happy Birthday Jett!!!
