Q1: Is the Finderscope Polar Axis included in the Advanced Series C8-SGT XLT Coatings package? and is the cable to connect the telescope to PC included so? Thanks.
A: Both of those items must be purchased as accessories.
Q2: I am comparing the Celestron Nexstar 8i SE and the C8-S GT (both with XLT Coatings). Can you help with a few explanations: 1) What is the difference between a StarPointer finderscope on the Nexstar and the 6X30 finderscope on the C8-S GT? 2)What is
A: A StarPointer finderscope is a nonmagnifying device that lets you point your telescope while scanning the sky with both eyes. Its mirror lens projects the image of an illuminated pinpoint into the line of sight, providing a red dot of light to center on the object to be viewed. A 6x30 finderscope, on the other hand, is a little telescope in its own right. There is no weight difference between the two scopes; it was a transcribing error on our part. Both optical tubes weigh the same: 24 pounds. Resolving power is the ability of a telescope to distinguish very close objects from each other, and it's expressed in terms of arc seconds: the smaller the figure, the better the optical quality of the scope. Resolving power of .57 means the scope can differentiate two objects that are only .57 arc second apart. For reference, 1 arc second is about the size of penny viewed at a distance of 2.5 miles.
Q3: I am interested in purchasing a C8-S with the XLT coatings but NOT the GoTo feature. I see it elsewhere, but not on Telescopes.Com, is there a specific reason for this?
A: Celestron has discontinued the non-GoTo members of its Advanced Series telescopes. Some dealers may still have a few of the non-GoTo C8-S scopes around, but when they're gone, there will be no more for sale. Celestron is now making only the GT versions of the C scopes.
Q4: If I ran out of battery, can I manually slew the telescope? I understand that controller or GOTO will not be available. But, I want to know if this telescope without any external power is as good as a Dobsonian.
A: No. Without a source of power the Celestron Advanced Series C8-SGT Schmidt-Cassegrain Telescope cannot be slewed or rotated in any way and would not be as good as a dobsonian.
