This lens really does bring the stars to life
it's definitely a game changer for widefield. I am very happy to have it. Clear skies
I've managed to take some decent images so I'm pretty happy for the price I paid.
I have got the sv555 last week, it has no focussing issues, and also improved the overall finish and reduced the weight by 90g.The new lens really does bring out the beauty of the stars!
I have been shooting with the SV555 and a Sony A7 III on a SA GTi for a few months now. I'm really happy with it!
The SV555 is probably the cheapest small telescope that can support round stars over a full frame sensor with a decent reach/focal length.
I have had it since January and enjoyed it a lot! I was about to get a redcat but... this one had slightly better reviews, a better look (IMO) and half the price. It is riding on my Juwei-17 mount and I am happy with the results. Now just need more time on the targets. Cheers.
I have got the sv555 last month. I'm over in darker skies of Nagano. I have already tested it but with a filter drawer on a Player One Poseidon-C Pro. I can achieve focus easily and the stars looked nice and round on 300 second exposures.
I think, for the money, the SV Bony SV555 lens does a good job for astro-imaging, and it offers the features that enable it to be used for traditional terrestrial photography too.
I got one its beautiful, I paid full price and got a receipt to prove it.
I really liked it and gives a lovely widefield shot at a good price.
