Hi everyone, has anyone got any experience with Kson products.
From what I can find, they are made in China and like most products, their focuser would be the first upgrade.
They are selling here for $800 for an 102mm f6 (http://www.australiantelescopes.com.au/telescopes/refractor-telescopes/buy-kson-ekinox-ed-doublet-apo-apochromatic-102mm-4-inch-refractor-telescope-ota-on-sale.html).
Fast and affordable, but what's the catch?
I looked on CN, but not much luck.
Thanks,
Bo :thumbsup::help::thanx::confused2:

anyone can make up there own brand - they also have some orthos - i think you'll find the scope ok - will be in the same league as any short-ish ED doublet, will be some colour but good value - if you contact some of the chinese manufacturers its an eye opener to see what some of the goods cost you,
there was a guy on CN selling them for 700 ish -

when you factor in focuser upgrade plus flattener - looking for a secondhand good scope can be just as cost efffective

Thanks Daniel,
I was talking to the guy on CN, he is selling the OTA with case for $550 now. I don't know what glass is used and CA.
My brother is pricing a few ED OTAs for me at the moment in China, so if he comes across any good prices, I will let others know so we can aim for a group discount.

Apparently there was a test report on 102mm f6 in the April 2011 edition of Aust Sky and Tel, page 80.
If anyone has a back copy, I'd be interested in borrowing it or have a scanned copy of the report.
Thanks again,
Bo

Here you go....MrB

There's no indication of the type of glass.On the end it just has ED High definition Optics.
Looking at Kson's website I don't think it's ED/APO just ED glass.

I have had it out a few times and am very impressed with the view through it.
It performs well with all my EPs even my TV 4mm Radian.
I have taken some shots of the moon with it and my 600D and am also impressed.
I don't have any sort of flattener/reducer but it still works very well.Of course having the moon in the centre of the FOV helps too.
I should mention that Colin had a Moonlite focuser fitted that definately helps
but I reckon the glass is very good going by the views and the sharpness of the moon photos.
Quite a few didn't need any sharpening.
I haven't noticed any CA either.Then again I haven't done any longer exposures yet.
