Product description

The AIRY BLACK 90T apochromatic refractor uses a triplet objective with FPL-53 lens that, thanks to the perfect chromatic aberration correction, generate detailed and rich in contrast images. It's the perfect instrument for long exposure deep-sky astrophotography of weak objects like galaxies, nebulae and star clusters.

Who wants to use large sensors cameras (such as DSLR cameras) can use the optional "Deluxe 2.5" field flattener for 90T" that can be directly screwed on the focuser of the telescope (to prevent flexures). This way you get a great flat field corrected for sensors up to FullFrame (24x36mm)!

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!
