The off practice Guider is an important accessory for astrofotography in long focal lengths, as it enables the highest support accuracy. The Celestron's off-get-together user uses a prism to distract a small part of the light from the image level of the telescope (and outside the visual field of the main camera) so that you can follow a guiding star. Every movement of this star corresponds exactly to the movements, which the main camera also sees. For example, an autoguid cancellation error can compensate for additional sources of error such as bending or overburdening the lead tube. The result: needle -sharp stars. - The most precise method for tracking = greater accuracy compared to a leading tube - multiple -supplied 12.5mm prism with aluminum -coated back for maximum relexion and a light image for the autoguid - helical focuser with a fixed ornamentation for light, exact and precise focus on autoguid 48mm free opening allows the use of full-frame cameras without vignetting- adapter for the correct distance of SLR cameras, night-cap CCD cameras and other widespread cameras for astrophotography- ideal for Schmidt- Cassegrain and Edgehd Telescopes
