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
 
Twilight I Adjustable AZ Mount
The Twilight II is a light-to-medium-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 or ED102mm, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the Explore Scientific Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go.

The Twilight II alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith.

Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment.

The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum.
