The four-element reducer is a 0.84×optical device which can change the the FMA230 into a 50mm-aperture astrograph with a focal length of 230mm and a focal ratio of f/4.6. The reducer is designed specially for sophisticated astrophotography, which plays an essential role in improving the image quality generally across the whole field of view. And it pays special attention to the stars at the edge of the image. The pictures will be greatly enhanced and detailed under the help of this dedicated reducer even the imaging equipment you use is a rather professional full-frame ordinary or astronomy camera.
Askar FMA230 is equipped with useful standard accessories.
The pair of tube rings are artistically pierced. Its stalks are lengthened which means that the tube rings provide more room for the devices, like a camera, that are attached to the FMA230, so they won’t collide with the dovetail plate under the astrograph.
The FMA230 comes with a Vixen-style dovetail plate. Screw the tube-ring-wrapped astrograph onto the dovetail plate and then directly slide the assembly into the slot on top of an equatorial mount. The slot at the center of the dovetail plate is carved for the attachment to a tripod. It’s quite convenient and helpful especially when you carry out some ground imaging or observation.
In order to solve the awkwardness of carrying around your astrograph when you engage in field astrophotography, the FMA230 is designed with a pretty-looking and utility handle. The detachable handle is installed on the top side of the tube ring. The handle is not just literally a handle, the dovetail slot carved out of the handle can also be a base for the attachment of finders, guiders or ASIAIRs that have a corresponding dovetail foot. So you have more room to integrate as many accessories as possible. Besides, the handle is carved with 45°Arca-swiss style slots at the sides, so an upside-down handle can be directly slid into a corresponding Arca-swiss clamp on a camera tripod.
The lightweight and compact FMA230 is a new sibling from the Askar FMA- family, it will definitely bring your observing and imaging experience to a whole new level!
