This one is the one I have Please see below subs on the configurations: Image - Configuration 1 Configuration: 2600MM Without Backplate -> EFW -> 22.5MM Extender -> Coma Corrector Image - Configuration 2 Configuration: 2600MM With Backplate -> 2MM Spacer -> EFW -> 16.5MM Extender -> Coma Corrector Apologies if these images are naff, still learning as I go only have these two subjects currently

Indeed, it has a title plate included that is 5mm, with it removed and the efw bolted directly on, its 12.5mm, 17.5mm with the black plate. Have tried both configs

Hi all, New to the hobby and forum, need a little help with setting up and configuring the kit in the title. Using an 8" Quattro F/4 and the Skywatcher Coma Corrector. Suffering miserably currently with edge of view star warping. Have tried the following two configurations (all distances in mm): Config 1 Config 2 Camera 12.5 Camera 12.5 EFW 20 Tilt Plate 5 Filter 1 Adapter 2 Adapter 22.5 EFW 20 Coma 0 Filter 1 Adapter 16.5 Total 56 Total 57 Required 56 Required 56 Required backfocus for the CC is 55mm as is the camera but struggling with getting the images with the above configs to look decent. Still have severe warping at the edges of the image. Anyone with more experience and expertise on this would love to get your thoughts or even someone with the same kit. Havent been able to find any help with this currently. Many thanks
