What we liked
- + Matched to the SV503 102mm ED for correct optical design
- + Flattens field curvature for sharp stars across the frame
- + M54X1 thread gives a secure, tilt-free attachment to the focuser
Trade-offs
- - Check the reduction factor specs to confirm fit with your setup
- - Limited to the SV503 102mm telescope, so it will not move with you to a new scope
