3吋Stellarvue調焦座用低輪廓目鏡背板 (DCQSV3)

Finally a visual back that actually keeps my eyepieces snug without any wobble—the compression ring clamp locks down tight and releases smoothly. Slips right onto the 3" focuser with zero slop, and the low profile design means I don't have to rebalance the scope much. Exactly what I needed for crisp

The compression ring clamp holds my heaviest 2" eyepiece securely without any play, and the reduced profile lets me reach focus with my binoviewer setup. This is exactly the right adapter for the SVQ100.

Swapping out the stock adapter for this low profile version really cleaned up the rear of my scope. The compression ring clamp holds my 2" diagonal firmly without any slippage. A simple upgrade that makes a noticeable difference in the setup.
