It’s just too good to have the best optical cleaner.What do you guess? Lenspen? No, it’s just too small to be efficiency in cleaning telescope. It’s the Purosol Optical from Origin Lab. It’s a must-have for every amateur astronomer to keep their lenses and mirrors clean. Don’t forget to get Purosol Mircofiber to enhance the cleaning result.

Lunar GOTO v1 is a software which allows you to select any of the 1,985 features and observe them on the Moon. You need a telescope mount which is LX200 commands compatible so that it’ll be able to drive the mount to GoTo the site you selected. For example, Meade LX series & ETX series, Skywatcher HEQ-6 and many other. Just check with the manufacturer or go through the forums whether your mount is applicable.
Since I haven’t requested the permission from the author to enclose the download link of the software here, you have to go to the location below. (Hey, not using your telescope!

Yeah…. I know this is a bit late (very late?) to wish everyone Happy Chinese New Year! Yup, this festival is not only for Chinese since the global vilage concept is advertised. The photo above shows the angpao that I collected from my family, relatives and friends. Have you collected any?
Festival is always good but for me, it isn’t. We always have fireworks to celebrate this annual event. I’m not sure whether the fireworks will polute the skies but from the view of an astronomer, it makes the sky not so perfect for observing and imaging. Oops, I just remembered that I didn’t take any photo of the fireworks… What a waste…

New Horizons is a spacecraft designed for discovering the “ex-planet”, Pluto. It was launched at 19 January 2006. It’s going to flyby Jupiter on 28 February 2007 as it needs the strong gravity of Jupiter to accelerate to a higher speed to reach Pluto in 2015. I am quite sure that New Horizons will break Christopher Go’s Jupiter Imaging Job.
The distance between New Horizons will be shrunk from 40 million to 2.24 million kilometres. Until then, New Horizons is able to use its high-resolution imager (LORRI) to image Jupiter. Its resolution is believed to exceed the highest resolution that HST can archieve. LORRI will take its best full-disk portrait of Jupiter, just before the giant planet fills the camera’s field of view. So, let’s wait for the mouthwatering photos! Time to know more about Jupiter.
Below is the species of fungi that grow on lenses and mirrors.
Enicillium spinulosum, Thom.
Penicillium commune, Thom.
Penicillium citrinum, Thom.
Aspergillus niger, Van Tiegh.
Trichoderma viride, Pers. ex-Fr.
Mucor racemosus, Fres.
Mucor ramannianus, A. Moeller.
Aspergillus niger
Aspergillus fumigatus
Aspergillus candidus
Penicillium sp.
Paecilomyces sp.
Syncephalastrum sp.
Sepedonium sp.
Cuvulvaria sp.
Fusarium sp.
Monilia sp.
Cladosporium sp.
P.S.
Your body is smarter than you are; it considers your head and vital chest organs to be the most important parts of you. It will try to maintain their temperatures at all costs. If your uncovered head is causing you to lose heat faster than your body is producing it, your body will begin shutting down the circulation to fingers and toes, and then arms and legs. Your outer extremities will become frostbitten to maintain your brain at proper operating temperature. The moral is: To keep your toes warm, cover your head.
