Hi Eteny, I also have this exact same binocular which I bought last year at Camerahaus. Excellent optics and construction. only thing is with this power and magnification, a sturdy tripod and a binocular to tripod adapter would be a must. Both of these accessory is available at the same shop in Robinson’s Galleria. I highly recommend this to anyone wishing to view the night sky without the use of a telescope. Best Regards, Richard
Hi Richard!
I also purchased my binoculars from Camerahaus, in Mall of Asia. I realized that there are only very few sellers of decent binoculars here in our country.
