Basically the apo can be combined with all suitable correctors. We especially recommend the following correctors, which are linked in the recommended accessories.
TSFLAT3 - 1.0x corrector
The corrector is screwed directly onto the M92 thread of the focuser. The corrector provides illumination and correction up to 60 mm image circle diameter. The focal length is not changed.
TSRedJM63B - 0.8x corrector
The corrector is screwed directly onto the M63 thread of the focuser. It reduces the focal length to 992 mm and improves the focal ratio to f/6.4. The corrector provides illumination up to 42 mm image circle diameter.
TSAPORED075 - 0.74x corrector
The corrector is screwed to the M92 thread of the focuser with the Adapter M92A-M88i (optional, linked in the accessory section). It reduces the focal length to 917 mm and improves the focal ratio to f/5.92. The corrector provides illumination up to 44 mm image circle diameter.
