กล้องเล้งดาวเหนือ Sky-Watcher Polar Scope for EQ3 / EQM-35 / HEQ5/ CG4

• Suitable for Skywatcher EQ3, EQ3-2, EQM-35 and Celestron CG4 mounts. 
• Improved version with screw connection to mount 
• Precise polar lignment of the mount (for e.g. astrophotography) within a few minutes. 
• For using the polar scope you need an unobstructed view of Polaris. 
• This new version supports the Kochab method, which can easily found in the internet, for showing the correct position of Polaris on the reticle. 
• This polar scope also works on the Southern Hemisphere, by using the position of sigma Octantis

The Sky-Watcher Polar axis finder scope speeds up and refines the polar alignment procedure so the observer can spend more valuable time observing, rather than setting up.

FF80APO 0.76X Full Frame Reducer

ZWO has released a new 3-inch FF80APO 0.76X full frame reducer with a three-element optical design, including one element made of ED glass. Its reduction factor is 0.76x, which gives the FF80APO f/7.5 astrograph a shortened focal ratio of f/5.7 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a rear interface that attaches to the FF80APO telescope tube’s included four-segment camera extension tube. The back focus is the standard 55mm, and it has a built-in M48X0.75 2-inch filter thread for easy attachment.
