Looks same but the TS says it is good for full format and the skywatcher not.

Thanks
Andre

Hi André,

I have the TS optics-GPU one. It is really good. TS optics sold another GPU non-TS that was almost the same, without the ring though. I don't know if the Skywatcher is identical (it is not specified on their site if it also has 4 elements, that's important). Both are not optimal for full frame they are 2''. For full frame you need 3'' to decrease vignetting but that requires changing everything sometimes from the tube (or drilling a 3'' hole), focuser, filters… I would go with the TS.

Best regards,

Bogdan

They are the same, i have that Skywatcher F4 Aplanatic and it is 4-elements, same as GPU, i am sure they are all manufactured the same but then rebranded under different name.
