Omegon T2 Extension - Precise distance, sharp image<\/strong>
Omegon T2 extension - 30 mm gives you the extra space you need in your image train. This puts your camera, flattener or filter wheel at just the right distance. Your image stays sharp and even, so you spend less time searching for focus.<\/p>\n\n\n\n

Simple and firm coupling<\/strong>
Telescope side with T2 internal thread (M42x0.75). Camera side with T2 external thread. You screw everything on directly. It's tight, straight and hassle-free.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Reliable alignment<\/strong>
The extension piece keeps your optical pad centered. This helps prevent tilt and backlash. Result: tight stars all the way to the corners.<\/p>\n\n\n\n

Flexible stacking<\/strong>
Combine with other spacers to achieve exactly the right backfocus. Quickly build your ideal setup without additional adapters.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Backfocus fine-tuning: add 30 mm in a T2 chain
\u2713 T2 (M42x0.75) compatible accessories: direct screwing
\u2713 Flattener\/reducer\/filter wheel with T2: correct distance, sharp image
\u2717 M48 systems only: use an M48 extension or T2-M48 adapter
\u2717 Visual use without T2 thread: not intended<\/p>\n\n\n\n
