To provide customers with more options, Askar has launched the new FMA180 pro. FMA180 pro is similar to the FMA180 in optical design. The objective lens features a sextuplet air-spaced APO design and includes two pieces of ED glass, providing excellent correction of chromatic aberration. In addition to visual observations, the FMA180 pro is specially optimized for astrophotography. Compared to FMA180, FMA180 pro adds a finder base and a 360° rotator. What' s more, the focuser is designed as internal focusing which promotes its stability and ensures its performance in use as a delicate, high-quality, and compact astrograph.

• 40mm aperture
• 180mm focal length
• Two-ED glass elements APO
• Internal focuser
• 0.8kg Lens tube
• 360 Degree Rotator
• 150mm vixen dovetail plate
• Finder base bracket
• Supporting full frame
• Built-in reducer

• 1” square sensor
• The IMX533 is a 1-inch, 9MP CMOS image sensor in a square format with a 3.76 um pixel size, capable of producing frames at 20 frames/sec in 14bit mode.
• Read out noise is as low as 1.0e which makes it comparable to SCMOS or EMCCD sensors and highly suitable for high definition, low noise imaging.
• IMX533 backlit sensor
• Zero amp glow
• Low read-out noise, high dynamic range

• Engineered specifically for use with DSLR, CMOS, and CCD color cameras
• Suppression of optical density (OD)4.5 on unwanted visual wavelengths adds signal-to-noise
• Extremely steep bandpass edges minimize internal reflections
• Ideal flat- top and moderate bandpass reducing spectrum down shifts
• Ion Gun Assisted Deposition coating technology on the double-sided polished substrate making it the most consistent and accurate light pollution suppression filter
• Good performance at focal ratios faster than F3.0 with contrast increasing as focal ratioincreases
• Designed to suppress artificial lighting from Bortle scale 1 to Bortle scale 8
• Near IR (NIR) is blocked up to 1100nm

NOTE: DO NOT LOOK AT THE SUN WITH ANTLIA FILTERS. Serious eye damage will result if you fail to observe the warning.
