Seben Telescope.

I know nothing about these scopes to be honest, but I saw this and thought it may be worthwhile to someone.

I am tempted myself but with Christmas coming up I will have to give it a miss.

The owner has posted information from a catalogue I think, but he admits this at the bottom.

I heard Seben scopes uses spherical mirror rather than parabolic, so image quality will be poor. That mount is not a EQ3. A EQ3-2 has a polar scope hole, that Seben mount doesn't.

"Transporting and setting up is more a child?s play and with the catadioptric technology this telescope is sturdy even in outdoors not shaken even by the stormy winds."

I don't know what this supposed means. Catadioptic describe telescope designs that use a combination of mirrors and lenses, such as SCT and Mak. It has nothing to do with Newtonian and even less to do with the mount.

A newtonion like this being described as catadioptric usually means that the focusser drawtube will have a built in (probably low quality) barlow in order to increase the focal length - this is 1400mm focal length, but the tube isn't long enough to be a standard newtonian of that focal length :)

I think Skywatcher used to have this on one of their very basic models (the Skyhawk 114, not to be confused with the skyhawk1145p which has a parabolic f5 mirror).

I'm reminded of a thread a few months ago about Sebens, which descended into a list of the 101 uses of a Seben OTA. Here was my contribution: A strawberry planter.

What puzzles me is that, if they are as bad as they appear to be, even though they aren't really any cheaper than Sky-watcher, which makes decent but affordable products, why:

a) haven't they gone bust, or

:) don't they make decent scopes to compare with Sky-watcher? It can't be cost, because if Sky-watcher can do then so should they.

We've had families bring them along to stargazing nights and, with a bit of a tweak here and there, I wouldn't say they are completely worthless. They seem a bit under-mounted if anything.

Obviously not for anyone in-the-know, but still something for a kid to get started with.

The clear 'not winner'. At least the National Geographic (poor) efforts are sold as toys. My sister got one for my youngest a couple of Christmases back and it was hopeless. He much prefers looking through my little 60mm mid-70's Prinz frac or a little pair of bins.
