Re: Finder for a bino
It is not necessary to have a finder for a binoculars because its Field of View is already very wide. You can use a iPhone with astronomy app that allows compass and inclination. 'Point' the iPhone towards a bright star or planet and from there the astronomy app will tell you which star/ planet it i...

Re: Hubble Optics 16" f/4.5 UL Dobsonian - thoughts anyone?
Hmm.. never read any review or seen any pictures of this scope before. If you were to take on this route, it will have its risks in terms of optical quality, stability of the design, movements of the dob (not all dob move smoothly), vibration and ease of assembly and collimation (including stability...

Re: What do you guys use for dew control?
If you are observing for about 2h in Singapore.. usually it is not necessary to have a heater/ heat pack. It is necessary to have a dew shield for the refractor or Cass though and it has the extra benefit of preventing stray light from street lamps from entering the objective lens. For the telrad fo...

Re: Advice on getting new telescope
16" is a very big and heavy scope. The pictures tend to show them 'smaller'. However a 16" will be pretty powerful instrument for planetary and for DSO. However, do note that extended dim objects like galaxies and nebulae will still not be seen well in Singapore despite the increase in ape...

I don't use such weather stations, however, I constantly monitor the satellite images around our regions. http://www.wunderground.com/global/stations/48698.html Wunderground has quite a high frequency of updates.. in few minutes interval and I found it one of the most reliable source of weather info...
