However after doing a bit of research it appears that the Skywatcher Quattro Coma Corrector is exactly the same (except for a removable ring on the TSGPU that is not removable on the Skywatcher), both produced in the same factory, although the Skywatcher is up to $100 cheaper. I found that information here, here, and here.
Does anyone have any additional information on whether or not they are the same? If so, is the TSGPU removable ring useful?
Many thanks,
Stéphane

Stephane,
The SW Quattro was designed specifically for f3.5 to f4 focal ratios to complement their Quattro range of black diamond premium Imaging newts that came out in 2019
The TS GPU is designed for f4 to f6 focal ratio’s and they work beautifully on f5 and f6 , I have the photos to prove it.
Please speak to Diego at Sidereal Trading and he will definitely recommend the TS GPU CC with brass sleeve. The brass sleeve definitely reduces tilt or slop in your focuser. I could never get my Baader Mk3 to sit square, the TS GPU solved the issue
By all means get other folk to comment on their experiences with f5 newts and coma correctors. The TS GPU CC immediately solved my issues , a quality piece of optics !!
Cheers
Martin
