Flat6AIII الجديد القابل للضبط (حامل T غير متضمن)

Finally, an adjustable flat6 that actually holds its position once set. The helical locking ring gave me precise, repeatable back focus adjustments without any slippage during imaging. My stars across the whole frame look noticeably rounder than with my previous fixed-length flattener.

The adjustable back focus on this flat6aIII is a game changer for dialing in perfect stars with my reducer. It cut my setup time in half compared to my old spacer rings.

I was pleasantly surprised by how compact the whole setup is compared to my older flattener, and the threaded adjustment ring clicks into place with reassuring precision. First light images look much sharper across the entire sensor.
