Re: First scope for a newbie. Is this a good start?
Hello! Are you located in Singapore or in another country? That does make a difference between price, availability and light pollution.
Also, what's your budget and do you know what you're enjoy seeing?

Looking for Obbing buddies with Flexi-hours
Hello! I'm looking for friends to join for the occasional, ad-hoc observation session in JB As my off days are usually weekdays, I can't join the usual weekend new-moon sessions and weekdays tend to be the days I head up north for a session, usually just an evening, returning to Singapore about 1-3a...

Re: Unexplainable moving object near moon - 0300hrs, 19Apr14
Good points. I stand corrected. Still, it would have been a nice thought. On the other hand, although the object itself would be invisible in a telescope, I wonder given such a bright background whether the eye might actually see something, or its shadow, for that matter. Could have been floaters in...

Re: Comments on takahashi scope
What are you hoping to achieve, as in what improvements are you hoping to obtain, how are you going to mount it and how much is your budget? :) A good 4" APO will be a definite improvement from the 80ED. The 90 - depends on the quality of your 80ED. It increases the light gathering by about 25%...

Re: Comments on takahashi scope
In short, no, unless you are trying to downsize your setup. Yes, it has the legendary takahashi optics but it is significantly smaller than an 80mm, allowing only more than half the light throughput of an 80mm (very significant) and its resolving power will be accordingly less as well, not that a 2&...
