ZWO FF 65 APO Refractor Telescope (ZWO-FF65-APO)

ZWO FF 65 APO Refractor Telescope (ZWO-FF65-APO)ZWO FF65 APO Astronomical telescope The ZWO FF65 APO is a refractive astrograph with the powerful flatfield optical design which saves you from the expensive cost of a field flattener. It eliminates the trouble of calculating the back focus distance of the flattener and connecting various accessories to achieve that distance. You can just connect any possible accessories you need. As long as the target is focused, the whole optical system is perfect

ASIAIR Mini is made out of aluminum and processed by CNC tech

invented Celestron's proprietary method of producing Schmidt corrector plates for superior views and maximum portability

random horizontal banding can be removed with multiple frame stacking so it does not affect the final image

It is used on a digital camera and the video

While the sulfur element does not have much scientific significance

further reducing the focal length and thus shortening the exposure time on its original 400 focal length and f/5

please use a separate 12V power supply rather than the power hub in the ASIAIR Pro as the hub cannot provide enough amperage to power the camera's TEC coolersASI6200

The reducer is equipped with fine focal adjustment function for more precise calibration in practical observation or sky imaging

With shorter tubes

and has integral placement of the focuser knobs

And users don't need to worry about the calculation of back focus when using FRA400
