The camera has a standard T thread connection on its front and can be used with our new Filterwheel and Off Axis Guider unit. For focal ratios of F5 and above standard 1.25 inch filters can be used without vignetting. Faster focal ratios will need flat field correction or larger filters (36mm or 2inch). The camera body and shutter will work down to F2 without vignetting. Proprio non so leggere..... In effetti qui dice che i filtri da 1,25 basttano ed avanzano! basta fare un bel flat!
