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:
- Protective T-ring Body
- Temperature Compensation Ring (for installation of 50.4mm x 3mm unmounted filters)
- Adapter S52/M48 (for 48mm connection thread)
- T-thread/M48 adapter (for standard 42mm T-thread connection)
- S52/2" wide aperture 2" nosepeice (includes M48 filter thread)
- 1.5mm Allen Wrench
In addition to the basic system, this Protective Wide T-Ring system also includes a pre-installed Baader 50.4mm x 3mm Clear filter with Phantom Group Multicoating.

The best.
Pros: Cons: Comments:After using a few different brands of T adapters I have to say I've never had any with a sloppy fit. The Baader stands out with the ability to place a filter in it. Keeps your camera sealed and clean inside. It comes with several different parts for several applications. I do wish it came standard with the special wrench needed to take it all apart, be sure to pick that up! Expensive, but I appreciate having my camera body sealed up while changing the setup.

Sep 27, 2013Protect your EOS
Pros:Easy to Use,Compact,Accurate,Quality Lenses,Strong Construction,Lightweight
Cons: Comments:This is the only T adapter I know that has a quality Baader glass filter installed between the camera and telescope. This is important to me as I know that nothing will enter the camera from the scope, especially when pointing overhead. Essential in my opinion in order to keep the camera optics clean. Highly recommended.

Jul 28, 2013Helps reduce vignetting
Pros:Easy to Use,Accurate,Quality Lenses,Strong Construction
Cons:None
Comments:A nice solid connection to my Canon t-3. Accepts 2" filters

Sep 22, 2012A Must for Astrophotography
Pros:Accurate,Compact
Cons:Ergonomically Inelegant
Comments:Dust protection is essential to high quality imaging. This product protects the sensor from the evil "dust doughnuts" that will certainly accumulate on the sensor when off the imaging train, and even when hooked up.
Bottom Line: Would you recommend this item? Yes
Switching from a 2" nosepiece to the 48/42mm adapter requires a screwdriver and good eyes. This is inexcusible, as all changes in configuration should be done without tools.This review was provided courtesy of AgenaAstro.com
