Digadapt

The first universal eyepiece projection adapter designed especially for digital imaging. The special design allows the adapter to collapse much further than conventional projection adapters allowing the close afocal coupling necessary to reduce vignetting. The adapter is "T" threaded, use the proper step ring to mate it to your digital camera or use a T-ring to mate it to your 35mm camera. Note: To use an eyepiece with this adapter it must not exceed the following dimensions: maximum diameter of top - 42mm, maximum height of top - 49mm, maximum overall length of eyepiece - 80mm
