This adapter from the M48 thread (2" filter thread) to the Nikon F mount allows a short adapter from the M48 filter thread without the smaller T2 thread. This improves the illumination and makes the adaptation to correctors with M48 thread possible.
T Ring from M48 Thread to Nikon F Mount
Description
Specifications
The T-Ring adapter fits to:
♦ All Nikon (D)SLR cameras
The T-Ring adapter is, among others, suitable for:
♦ Skywatcher field flattener / reducser for ED refractors (SKFlat80, SKFlat100, SKFlat120)
♦ Skywatcher coma correktor (Komakorrf4)
♦ Baader MPCC Coma Corrector
♦ TS Newton Coma Corrector (TSKomakorr)
♦ TS, Riccardi, TeleVue ... Flattener and correctors
2" connection to the telescope with full clear aperture without small T2 thread:
With the 2" extension tube TSVF230 you can adapt the T-Ring directly to a 2" receptacle without the bottleneck over T2. Of course, the TSVF230 again offers the 2" filter thread on the bottom side.
This allows you to attach your DSLR camera directly to 2" connectors and thus with full illumination even for full-frame cameras. You will find the 2" extension tube further down under the "recommended products".
Connection to correctors with the T2 thread:
The adapter reduces the M48 female thread to T2 without optical path. This allows you to use the adapter also for correctors with T2 (M42x0.75) connection.
