Product description

The AIRY ED72 apochromatic refractor uses a doublet lens with FPL-51 element fully multi-coated that offers superior correction of chromatic aberration, compared to the classic achromatic refractor, but at a lower price than the FPL-53 models. For this reason, the AIRY ED72 apochromatic refractor is perfect for those customers looking for a large diameter instrument but at an affordable price, very good for long-exposure astrophotography. It's also perfect for those who use monochrome CCD cameras with narrow-band filters for color images (the use of such filters cancels the small residual chromatic aberration and makes perfect the final image).

The short focal length and the fast focal ratio make it perfect for wide field astrophotography of many extended objects, which will be shown in their full extent also with cameras equipped with not too large sensors (and therefore not too expensive).

50,8mm Hybrid-Drive focuser: Often refractors are provided with Crayford focusers suitable for visual use but not for photo applications. In fact, during the long exposures required by astrophotography, this type of focuser can cause camera slippage moving the sensor out of focus. For this reason the AIRY APO65F telescopes comes with the new 50.8mm Hybrid-Drive focuser that adds, under the focuser tube, a rack and pinion thereby maintaining in position even heavy cameras. Below the focuser there's also a locking screw: closing it, you will be sure that your camera will not move any more!

The focuser also features a convenient 1:11 fine focus gear, particularly useful when you need to focus at high magnification. The focuser has a very long ride.

OnAxisLock is the accessories locking system that, compared to those using normal screw, offers a greater clamping force, avoiding any possible flexure (so it's perfect for astrophotography), it does not damage the connected accessory and it perfectly keeps the optical axis of the telescope.

All this thanks to a new locking device with double ring: just rotate manually the appropriate outer ring (designed to allow an easy grip, even with gloves) and you will get a perfect closure!
