Takahashi CCA‑250 Visual Adapter (TKA86005)

Takahashi CCA‑250 Visual Adapter (TKA86005)

The TKA86005 visual adapter brings the powerful CCA‑250 astrograph into the realm of visual astronomy without compromise. It converts the M54×0.75 rear thread to M43×0.75, enabling connection of standard Takahashi visual accessories like diagonal couplings.

Constructed to the exacting standards expected of Takahashi optics, this adapter preserves parfocality and alignment when moving between imaging and visual pursuits. The knurled outer sleeve ensures easy hand-tightening even in cool, dark conditions.

Cloudy Nights Community Insight:
Photographers and visual observers using the CCA‑250 relay that this adapter “lets me swing between imaging nights and visual observing without refocusing”—a small solution that drives big satisfaction.

Observing Tip:
Leave this adapter threaded in when not imaging; swapping between diagonals and cameras becomes a one-hand click, both smooth and precise under the stars.
