This 0.8x reducer from Askar is designed for their 103APO triplet refractor. The 0.8x reducer provides a wider field image for astrophotography, allowing the capture of larger areas of nebulae or star clusters, or to capture faint and fast moving celestial objects.
This 0.8x reducer brings down the focal ratio of the Askar 103APO to f/5.4. This reducer also acts to flatten the image field, as well, making this optimized for astrophotography.
A Full-Frame Reducer for Astrophotography
This 0.8x reducer from Askar is made for their 103APO triplet refractor. It supports a 44mm, full-frame image circle and weights just over one pound. The reducer itself also sports a three-element (triplet) optical design. The front thread is an M84x1. The camera end of the reducer provides M54x0.75 and M48x0.75 threads, allowing for the connection of a variety of cameras. In addition, an internal M48x0.75 thread allows for the attachment of 2" threaded filters. Backfocus from the M48 thread is the standard 55 mm. Once installed, the 0.8x reducer changes the focal ratio of the 103APO to f/5.44 and the focal length to 560.32 mm.
Installation Step One
Installation of the 0.8x full-frame reducer to the Askar 103APO is simple. Unscrew and remove the 2" and 1.25" adapters.
Installation Step Two
To complete the installation, unscrew and remove the dust cap of the 0.8x reducer. Then screw the reducer into the 103APO. Before attaching a camera, you may also install a 2" filter to the reducer using its internal M48x0.75 threads.

Thank you Laurence, the unit works very well with the speaker arrangement I have and has a clear sound, it has brought new life to these since my amp blew many years ago. Vaughan
