As many astronomers know, no single type of finderscope can be considered the end-all and be-all of sighting equipment. Many observers have multiple sighting devices on a single telescope. One of the most common combinations is the

I have had the frustrations in connecting RoboFocus with CCD Soft in the setup. Even though CCD Soft does have RoboFocuser in its pull-down menu, the user like me is confronted with a nagging error message in CCD Soft saying it Failed to connect to Focuser! After I got this to work, I documented it.

Collimation is the alignment of the optical parts of a telescope. Though lining up the secondary under the focuser is essential for uniform illumination of the field of view, there are only two alignments in collimation: the focuser axis (done by adjusting the secondary mirror), and the Primary Axis (done by adjusting the primary mirror).
