Alpine Astronomical M54 Fine-Adjustment Ring (0.3mm, Black)
This 0.3mm M54 Fine-Adjustment Ring, from Alpine Astronomical, is an aluminum spacer ring for fine-tuning the M54 system. It fits between all M54 threads and prevents binding between M54 parts. This 0.3mm ring is equivalent to approximately 2/5 of a rotational turn.
Alpine Astronomical M54 Fine-Adjustment Ring (0.5mm, Red)
This 0.5mm M54 Fine-Adjustment Ring, from Alpine Astronomical, is an aluminum spacer ring for fine-tuning the M54 system. It fits between all M54 threads and prevents binding between M54 parts. This 0.5mm ring is equivalent to approximately 2/3 of a rotational turn.
Alpine Astronomical M54 Fine-Adjustment Ring (1mm, Gold)
This 1mm M54 Fine-Adjustment Ring, from Alpine Astronomical, is an aluminum spacer ring for fine-tuning the M54 system. It fits between all M54 threads and prevents binding between M54 parts. This 1mm ring is equivalent to approximately 1-1/3 rotational turns.
