Multifunctional lens Askar FMMA135 APSC - 135mm F / 4.5

The high-quality optics produce an image of pure color and contrast and meet the highest demands in astrophotography and observation.

With the special APS-C F4.5 corrector, the Askair FMA135 with 30 mm aperture and 135 mm focal length (F/4.5) becomes a professional APO telephoto lens with 135 mm focal length for both landscape and astrophotography.

The internal blackening and multi-coating processor ensure high contrast and bright, flare-free images, even in difficult lighting conditions.

It is also possible to use 1.25 to nebula filters thanks to the thread in front of the lens.

FMA 135 as a telephoto lens
The manual telephoto APO lens is designed for APS-C formats. From the T2 thread, there is a working distance of 55 mm.

It is ideal for APN and mirrorless cameras, but of course also for dedicated Astro cameras.
The telephoto lens is so compact that it can also be used freehand. The high speed of F/4.5 allows short exposure times, even in difficult lighting conditions.

FMA 135 as an astrograph
Astrophotographers will be delighted with this lens. Stars all the way to the edge of the image will be just fine. With a working distance of 55 mm, it is possible to attach all common parts (DSLR, CMOS, CCD or mirrorless).

The multifunctional mount allows easy adaptation to a telescope or tripod mount that can be connected via the 1/4" female thread.

FMA 135 APO mini telescope
The objective provides sufficient working distance for 1.25" diagonal eyepieces and 1.25" standard eyepieces. You can make wonderful observations with a field or simply attach a guiding camera and have perfect stars when guiding.
