6" F/9 Ritchey-Chrétien Telescope with BRESSER EXOS-II German Equatorial mount
Advantages of RC Telescopes compared to MAC and SCT
F/9 is faster than a 6" SC or Mak
illuminated field is much bigger
you can attach 2" eyepieces and full size SLR/DSLR cameras without vignetting
two hyperboloidical mirrors with 96% reflectivity lead to a bright image
faster cool-down time and no dew problems because of open tube design without front correcting plate
enough back focus for all kinds of accessories
M90 extension tubes for easy reaching of the focus are optional. Spacer, to be placed between focuser and telescope
fixed mirrors and 2" Crayford focuser with 1:10 dual speed transmission - no problems with mirror shift
corrected field is much bigger compared with a 6" SC
