Friends from the European Union,the price you see is tax-inclusive, but AliExpress does not directly charge tax for ordersover 150 euros,so when you actually place an order, you will find that you only need to pay about80% of the price. For example, for a product of US$1,200, you will find that you only need to pay US$1,000 (not including tax) when you buy it. IfFrench friendshave problem that it needs to fill in theVATnumber, please contact the seller to solve it.
Other countries do not have these problems. thanks.

Includes dovetail rail compatible with CGE mount
Celestron's EdgeHD Optical Tube is a Aplanatic Schmidt Telescope design producing aberration-free images across a wide visual and photographic field of view. The optical system on the EdgeHD was designed to give an astrograph quality flat focal plane all the way to the edge of the field of view as well as reducing the off-axis star coma. What you will get out of your EdgeHD telescope are visibly sharper images, enhanced mechanical features, FASTAR compatibility, and superior performance all the way around! The difference in EdgeHD optics is that they produce a focal plane more than three times flatter than that from a standard Schmidt-Cassegrain telescope and dramatically flatter than other competitive coma-free designs. The EdgeHD design guarantees you visibly sharp stars across some of the largest CCD chips available today.
The new optical design and redesigned tube allow you to get the most out of your optics every night. Holding the mirror in place, thus reducing image shift when rotating are flexible tension clutches incorporated in this design. These flexible rods hold the mirror in place without using any pressure or force on the mirror assembly. This helps keep the image centered in your eyepiece or CCD chip. Tube vents on the rear cell allow hot air to be released from behind the primary mirror. These vents have an integrated 60 micron micro-mesh filter that guarantees letting warm air out without letting dust in.
