Starboosa M42 Spacer Ring Set, M42x0.75 T2 Extension Rings, 6-Piece

• **Flexible Spacing, One Kit:** Mix and match six rings (3/5/7/15/20/30 mm) to build the exact distance you need—adjust from 3 mm up to 80 mm total for imaging trains and projection setups.
• **M42x0.75 on Both Sides:** Every ring is threaded male-to-female for quick stacking and secure connections with T2/M42 components (T-rings, OAGs, filter wheels/holders, adapters). *Note: This is M42/T2, not M48.*
• **Sized for 1.25" Setups:** Designed to integrate cleanly into compact 1.25" systems where space is tight—ideal for small astro cameras, guide cameras, and lightweight optical trains.
• **CNC Aluminum, Matte Anodized:** Rigid all-metal construction with a non-glare anodized finish; cleanly machined threads help parts start easily and tighten smoothly.
• **Consistent Fit for Repeatable Results:** Accurate machining helps keep your camera train stable when you change spacing—useful when dialing in reducer/flattener distances and maintaining reliable focus positions.
