7 x 35 is a little small with very little light gathering power. For other applications like birdwatching, yes, it can be very handy. But for astronomy, 50mm is usually the minimum.

wah.. then have to buy new one??

hmm... my mum's friend has a telescope bought from China.. but i dunno how's the quality.. i heard from my mum that the scope is a 400X... and is around 5"... tomolo i am going to take a look with that..

Usually, from the box we can already tell 8) . Especially those that state in very big, bold fonts "400 POWER ASTRONOMICAL TELESCOPE" or something similar.

As a general guide, newbies are usually advised to stay away from scopes from Tasco and Bushnell. Their binoculars and spotting scopes are ok, but definately not their astronomical telescopes. Quality control is usually very poor, and those guys are not mainly into the astro biz anyway so their astro scopes are half hearted products from the factory.

They may be very attractively cheap, but have the danger of snuffing out the enthusiast's burning interest by giving him/her the impression that "Oh ... so *that's* it ?"

The only reputable 100% China/Taiwan-originated scopes in our global astro community are those from Skywatcher, Celestron and Orion.

And other than checking for general fit and finish of every exterior part, hardcores or those who know how will go on to test the optical quality of the telescope by applying what we call a "Star Test".

This is something like a thorough "X-ray" of the scope's optics and will tell you if the scope is "internally sound". Any optical defects will be revealed easily here

so how the "Star test" can be done?? hehe

Now *thats* an essay question if you want the proper explaination.

It's best shown to you and you will learn faster. Explaining it in writing can be quite tricky sometimes. Do you know that there is actually a book written all about this ? Hundreds and hundreds of pages thick

Perhaps our Site Admin Vin Snr can tell you a little bit on that.

As a side note, I think this thread is getting a little bit out of control here. Poor me was just trying to put up my demo 80mm binoculars for sale and now I even have to answer questions about testing scopes and star testing down here

Let's take all these non 80mm bino questions into the relevant discussion sections shall we ?

ooh.. sorry... i am too engrossed in asking newbie questions... :oops: :oops:

sorry to disturb ur thread, i already posted a new thread regarding that... pai seh!!! :oops:

Hi samuel,

Can you post a picture of the binocular... Also does it come with a bino mount..

cheers
Addy

Hi,

It comes with the threaded hole for the L-adapter for tripod mounting.

I can give you the heavy duty L-adapter (worth S$40) with the bino free of charge if you do get it from me at my asking price.
