Baader DSLR-2" Filter Holder M48/SP54
- Allows the mounting of Baader 2" filters
- Needs Hyperion DT-rings #2958028 - 2458062 and additional Stepper Rings M67 up to M82
- All Baader 2" filters in version M48 thread can be customised with specific extension tubes on almost all DSLR lenses.
Many astronomical filters can be used with a DSLR-camera lens. Baader's largest cell mounted filters measure 2" in mechanical diameter (having a metric thread of M48). The clear aperture is 46 mm.
In order to ease the adaptation of Baader 2" filters onto most camera lenses, Baader produce a general-adaptor, to convert from the ASTRO-2" Standard (M48) into a more common photo-standard of SP54 mm. This ring is named: DSLR 2" FilterHolder M48/SP54 (item #2408166 - i.e. the ring on this page).
Individual lens adaptors for most camera-lens threads are available to fit onto this filter holder. Larger lens threads may be utilised by adding another 62 mm stepper-ring.
Lens Adaptor Ring: SP 54/M46 (#2958046) / SP 54/M49 (#2958049) / SP 54/M52 (#2958052) / SP 54/M55 (#2958055) / SP 54/M58 (#2958058) / SP 54/M62 (#2958062).
Step-up Rings (for cameras lenses with thread larger than M62): M62/M67 (#2968067), M62/M72(#2968072), M62/M77(#2968077), M62/M82(#2968082).M62/M67 (# 296 8067), M62/M72 (# 296 8072), M62/M77 (# 296 8077), M62/M82 (# 296 8082)
The animation below shows how it works: The lens thread adaptor (in this case M62 or M55 or M49) fastens onto the camera lens, next comes the Filter-Holder M48 (# 2408166) and lastly any 2" (M48) Baader-filter will thread onto the assembly.
