Meade GOTOs with the Autostar can track satellites provided you update it with the latest orbital information of the intended target.

I don't think so , coz if a tracking antenna can track satellites and they appear visible for at least 10mins when they come over our horizon.

The astro bargains owner, Joo Beng, is overseas alot of the time. Maybe give him a few days to check his email/PM.

That means his store is not open one ? I just want a place to go down to check out the gear. Like that i think i go science centre better.

Hi,

Tracking Antenna?? I believe the tracking antenna don't need to track like a telescope because it got a very large field. A telescope field will be very small at high magnification (you want to see satillites??)... the usual Field of View is around 0.5 degree or less at high magnification. It is a very difficult task to keep a moving object steady in the 0.5 degree Field of View.

Have a nice day.

Actually the bigger the antenna , the finer the resolution it can track or resolve. If a large antenna can track a moving object , which stays in sight for abt 10mins in our horizon or communication zone , isn't that enough time to snap a photo? , worse come to worse , we can at least do Geo Stationary but that is 36000 km away so i guess it won't be great quality.

Btw i noticed that no one suggested kent ridge hill as an ideal place to for observation? only distraction is a 13m tracking antenna.

Joo Beng's stall is his house near Adam Road. He has quite a lot of astro stuff in his house.

Patience is a virtue, young man :) Believe me, you'll be rewarded for it.

Joo Beng is indeed one of the nicest dealers I have come across. No doubt there seems to be no physical store front, it is perhaps one way to help him keep costs down and enable us to get our astronomy toys at very good prices. The name "Astrobargains" says something about the need to stay competitive in a niche market.
