ES x3 Barlow v’s Meade series 5000 x3 Barlow?

[Merlin66]

The ES ad makes the point that their  design for the tele extender is like a telecentric- magnification doesn’t vary with spacing.

Meade appear to offer the same design but don’t highlight the telecentric capabilities.

Has anyone had practical experience with the Meade x3 and can confirm or not that it is a telecentric design.

Thanks.

I have the Meade S5K 3x and it is a tele-centric lens. I also have the 2x and a TV 2.5x PowerMate, and all have about the same performance, as far as I can tell. I don't use the 3x that much, as I now use cameras with smaller pixels than before.

Thanks for that Micheal, appreciated.

I’m looking at the Meade x3 to use for solar imaging, it would give me a good plate scale, hopefully without newton rings.
