HOTECH - DSLR Precision 1.25-inch T-connectorThis product is highly recommended
Code: SCA-TA125
A high-precision T-Adaptor dream come true for serious astro-photographers

Finally a highly accurate Self-Centering Camera T-adaptor for Astro Imagers! This beautifully designed mechanism provides repeatable and reliable connection between your telescope focuser and the camera. The SCA T-Adapter fits any make telescope that uses 1.25-inch focuser or visual back and you can use your existing T-Ring for your brand of camera and thread onto this excellent T-Adapter.

The Hotech SCA Brings your Camera to the closest optical axis of your telescopes drawtube/visual back for BEST / flattest field imaging results.

The SCA T-adaptor center loads your camera in the drawtube/visual back with a simple threading of a compression ring forcing the built-in rubber rings outward radially, thereby centering the camera in the drawtube/visual back for optimal installation.

All drawtube/visual backs have manufacturing tolerances and the SCA-T eliminates this small or large slop very effectively.

It features patented rubber rings that expand radially outward to fill the gaps. This makes your camera seat firmly in the drawtube becoming part of your telescope for a secure and repeatable installation.

It eliminates unstable locking from thumb screws or unified compression rings which are not always as accurate as we'd like. The SCA T-adaptor adapts your camera without using the thumbscrew or the unified compression ring. Thus it copes with the imperfection of a drawtube / visual back tolerances very well indeed. Even small imperfections inside the drawtube like dents or scratches, are negated. In addition, even if the drawtube is slightly deformed in diameter, egg-shape, the rubber rings in the SCA will compensate the differences and faithfully centers your camera.

It's short profile design keeps the installed camera stable from low frequency oscillation transferred from the telescope in a windy environment. The back focus of SCA TA125 is 18mm measured from drawtube shoulder to the bottom T-Thread.

The all-around adjustable tightness rubber contact damps unwanted vibrations from the telescope provides you a sturdy attachment on your telescope for a stable image capture.

The 1.25-in T-adaptor has built-in 1.25-in filter thread.

So if you're serious about you're DSLR or other T-threaded camera for astrophotography, you cannot do without this wonderful leading edge adaptor for achieving nice flat camera adaption to your telescope!
