Askar FMA135 Astrograph and Triplet Apo with Flattener
The motto of Askar´s compact FMA135 is "small but mighty"! It is of course an ultra-sharp telephoto lens with fast f/4.5. Unlike the simple camera lenses on the market, the lens is also suitable for the modern, high-resolution astro cameras.
The 3-element f/4.5 corrector makes the ASKAR FMA135 a professional telephoto lens for both landscape and astrophotography. The internal blackening and the elaborate multi-coating ensure high-contrast and brilliant images without reflections even under difficult lighting conditions. The use of 1.25" nebula filters is also possible, thanks to the filter thread in front of the lens.
The FMA 135 mm f/4.5 as a telephoto lens
The manual APO telephoto lens is corrected up to full-frame. From the T2 thread you have 55 mm working distance. Ideal for system cameras, DSLR and of course astro cameras. The telephoto lens is so compact that it can be used hands-free. The high speed of f/4.5 allows short exposure times even under difficult lighting conditions.
The FMA 135 f/4.5 as astrograph
Astrophotographers will be delighted with this compact telephoto lens. Stars up to the edge are imaged crispy sharp, when using cameras up to APS-C format. With 55 mm working distance (T2 mount), you can connect all common cameras. The multi-function mount allows easy adaptation to the finder shoe of your telescope or to a piggyback camera mount via the 1/4" female thread.
