Ideal for serious astronomers requiring exact mechanical alignment, the QHY M54 spacer helps maintain sharp focus across your entire sensor.
Engineered Astronomy AdapterSeamless QHY Imaging Train Integration
Achieving critical backfocus is vital for deep-sky astrophotography, and the QHY M54 Female Spacer with 6 Through Holes - 020079 delivers the exact 3mm thickness needed for optimal optical performance. Featuring internal M54 female threading on Side A and six unthreaded through-holes on Side B, this precision spacer allows for versatile bolt-through attachment to compatible QHY filter wheels and optical accessories. Manufactured to tight tolerances, it eliminates tilt and unwanted mechanical flexure in heavy astro-imaging equipment setups. If your specific configuration requires threaded mounting holes rather than clearance through-holes, consider model 020078 instead.
