Product Info

Manufacturer Description

Today's large sensor digital SLRs and advanced imaging techniques enable amateurs to take spectacular high resolution and long exposure images that push the limits of modern telescope optics. Until now, the only means of coupling a DSLR to the telescope relies on the use of a standard mass produced camera T-Ring. However, T-rings, albeit convenient and popular, do have limitations:

  • The use of 42mm T-thread for the coupling causes a choke-point in the imaging train (typcially 38mm internal diameter), possibly resulting in vignetting in fast systems.
  • High resolution digital image sensors and their protective glass covers are highly vulnerable to dust that can enter the body each time the camera is coupled/uncoupled, or in open systems, particularly if the camera has been modified for full-spectrum use.
  • Many cheap T-rings are mass-produced for generic camera use, with general manufacturing tolerances and design, which result in a potentially loose bayonet fit that can cause focal plane squareness and long-exposure image shifting from lateral play and angular wobble.

Baader's New Protective Wide T-Ring System for the Canon EOS series cameras evolves the T-Ring and solves these issues.

  • The 2" wide aperture of the protective T-ring accepts 3 different attachment adapters, which are included with each T-ring: Standard T-thread (42mm), 2" thin profile nosepiece, and 48mm thread (astro filter standard).
  • The internal filter compartment is able to accept both Baader 2" mounted filters, and 50.4mm diameter unmounted filters for the widest clear aperture possible (47.3mm aperture).
  • The optimized design and tight manufacturing tolerances ensure the closest fit possible with the Canon EOS body. This avoids the occurance of focal plane tilt and image shift caused by play and wobble at this connection point.

The Baader Protective Wide T-Ring System includes 6 configurable parts:

  1. Protective T-ring Body
  2. Temperature Compensation Ring (for installation of 50.4mm x 3mm unmounted filters)
  3. Adapter S52/M48 (for 48mm connection thread)
  4. T-thread/M48 adapter (for standard 42mm T-thread connection)
  5. S52/2" wide aperture 2" nosepeice (includes M48 filter thread)
  6. 1.5mm Allen Wrench

 

Baader Canon DSLR T-Ring parts included

In addition to the basic system, the Protective Wide T-Ring system is also available with 4 different pre-installed Baader 50.4mm x 3mm filters: Clear, UV/IR Cut, UHC-S, and 7nm H-alpha (sold separately).

Baader part numbers: # DSLR-T or # 2958550

      5.0 Thread adapter

      Pros:

      Cons:

      Comments:

      Works as expected but make sure you have a filter to fit it or v
      Buy one with it as it is required to make it all fit. I printed a ring as a place holder. They should include one.

      5.0 Baader always delivers the goods.

      Pros:

      Strong Construction,Amazing Quality,Lightweight,Easy to Use,Nice Fit With Zero Slop,Accurate

      Cons:

      None

      Comments:

      I needed a solution to fitting my 2" LPS filter to my DSLR keeping it as close to the sensor as possible to eliminate any possible unwanted reflections. Baader comes to the rescue once again!

      Ingenious design, top notch construction, Even if just used as a basic T-ring adapter it fits to the camera with zero shift or slop. The perfect solution to my problem. Don't think twice just get it.

      5.0 Works as advertised

      Pros:

      Strong Construction,Accurate,Compact,Lightweight,Easy to Use

      Cons:

      Comments:

      The adapter is perfect for connecting my Cannon SLR to my telescope. Fit and finish are excellent. There is one threaded adapter ring that fits between the camera mounting ring and my eyepiece. This will often unthread instead of unthreading from the eyepiece. I've been considering putting a dab of Loc-Tite on the one threaded joint that I'll never have to undo. My scope does not have a tripod that tracks so the images that I've taken of the planets have been bury due to movement. The moon is bright enough to shorten the exposure time so results are pretty good. I have an old Canon 20D that is not the astronomical version.
