Canon Camera

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.  Up until now, the only means of coupling a DSLR to the telescope  relies on the use of a standard mass produced camera T-Ring.   Unfortunately, T-rings have failed to evolve with the demanding needs of the advanced astro-imager:

 

  • The use of 42mm T-thread for the coupling causes a choke-point in the imaging train (typcially 38mm internal diameter), 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.  
  • These commonly available 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.

 


The New Baader Protective Wide T-Ring System for the Canon EOS 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 x3mm 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, the Protective Wide T-Ring system is available with 4 different pre-installed Baader 50.4mm x3mm filters:  Clear, UV/IR Cut, UHC-S, and 7nm H-alpha.

Comments about Baader Planetarium Protective Wide T-Ring System for Canon EOS with Filter Mounting:

I recently upgraded from an entry level Canon XS to the 5D MKII. I was in the market for a new t-ring and this caught my eye. The 5D is not cheap... I really wanted to do everything I could to keep it clean as it seems dust and particles easily found their way on my old camera sensor. Fumbling around in the dark kicking up dust is going to happen. I decided to go with just the dust cover option as my camera is not yet modded. This product fit seamlessly and allowed me to utilize my existing t-adapter as well as reducers and flatteners. I have imaged with and without and there is no negative effects whatsoever through my Williams Optics Zenithstar 110 APO. It also attached to my camera body very securely...this is very important when auto-guiding as you cannot have any slop in your gear anywhere! This is a fantastic product that i would recommend to anyone!
