ASKAR FRA400C F/5.6 APO REFRACTOR SKYROVER-IP The ultra fast Riccardi-Honders astrograph

The ultra fast Riccardi-Honders astrograph represents the only true innovation in optics in the past few years

The QHY268M Pro I features a new front design that reduces the backfocus distance to 14

With this controller you can keep the temperature in the tube or around the optics only a few degrees above the air temperature

The QHY530 supports the floating ROI algorithm which is currently in experimental status

The AFW has M54 x 0

ASKAR FRA400C F/5.6 APO REFRACTOR SKYROVER-IP The ultra fast Riccardi-Honders astrographThe Askar FRA 400C f 5. 6 is a professional apochromatic Petzval quintuplet with an aperture of 72mm and a corrected field of 44mm in diameter. The lenses are assembled in two groups: an air spaced triplet on the front and a correcting doublet towards the focus. The objective lens includes two Extra Low Dispersion glass for a superb chromatic correction. Differently from standard ED refractors, the Askar 400C features a Petzval design that does not
