Telescope

SharpStar's 13028HNT is a tiny little powerhouse that similar size APO's simply cannot compete with, with a relatively large aperture blistering F/2.8 speed and well corrected optics it will image like you have spent many thousands more. For stable well corrected astrophotography nothing else comes close to a hyperbolic newtonian and this little telescope certainly keeps that mantra going!

All it ever asks in return is you know how to collimate a fast telescope :)

Camera

Player One camera may look similar to all the other Chinese cameras on the market but after a few years of testing we assure you they are far from it, lower noise, less banding and a global shutter not to mention significantly higher build quality and attention to detail.

All this stands the Poseidon head and shoulder above its contemporaries in our humble opinion.
