SVBONY extension tubes allow precise spacing adjustments between cameras, eyepieces and focusers. Ideal for achieving correct back focus in visual astronomy and astrophotography setups.
I received my SV905C yesterday. It was very well packaged and postal costs were very reasonable. The commiunications with the seller were excellent and I was kept informed about the progress. The item was new as described and was the perfect product to fulfil my needs as a fairly novice astrophotographer and a very good price
I would highly recommend this seller
Could not be happier arrived within 48hrs, unfortunately not had chance too test it as its been too cloudy and wet, very satisfied customer.
