The fast apochromat is very well suited for astrophotography. The robust 2.7" RAP focuser supports even heavy cameras, offers 360° rotation and has dual speed for precise focusing. We highly recommend the following correctors:
WiflatT2 - 1.0x corrector
The corrector is simply plugged into the 2" receptacle and is well suited for cameras up to APS-C format. The working distance is 55 mm from the T2 thread.
TSFLAT25G2 - 1.0x Full Frame Format CorrectorThe professional corrector is designed for full frame format. For connection to the apo, the M74-TSFLAT25 (M68x1 adapter) transition adapter is required. This allows you to screw the corrector directly to the focuser.
For the correct working distance (55 mm from the M48 thread) you still need a 5 mm M68x1 extension tube # TSVM685.
TSRED379 - 0.79x focal length reduction
To all astrophotographers for whom f/6 is not fast enough, we offer a focal length reduction with field correction. The focal ratio improves to f/4.74. For the connection to the apo you need the transition adapter M74-TSFLAT25. This allows you to screw the corrector directly to the focuser.
To achieve the correct working distance of 55 mm from the M48 thread, you still need 2x M48 tuning rings with 1 mm thickness # M48abstimmring1.
