Seems, hew design?
This scope has been around for nearly two years. Reviews aren't great,
but typical for the price and wide field. Google is your friend.
That's what it says, rich-field!
But is it flat field or what?
Just a plain Fraunhofer achromat and a fast one. Will have a bit of colour, not great for planets.
No rich-field scope is good for planets!
Made for photo and wide fields!
1. No, low-power, high-aberration rich-field achromats are the worst for planets.
2. Low-power scopes are poor choices for imaging planets.
3. Colour error bloats star images in deepsky photos.
This scope, I don't think can be used for photo either with that plastic focuser in the back?
Well, any scope can be used as a camera lens as long as it has a way to attach a camera, but it's an alt-azimuth mount so you'd be limited to terrestrial and moon/sun shots.
