Thanks Ben 👍
Have seen a few of your images on astrobin too actually. Quality work consistently. So to answer your question, i can get away with 31mm filters with a Skywatcher Aplanatic Coma Corrector, but def do get vignetting with a Paracorr II or the Starizona Nexus f3 reducer. The latter two have to have the focuser racked out a lot further than with the SWCC. If i could, id like to try a larger focuser on the quattro to rule out whether it's vignetting caused by the 2" focuser or not. Thanks though, for now, I'll have to crop when using the f3 Nexus with the 2600mm, or perhaps drop back to 1600mm 4/3 sensor.
