2\"\u003c\/h2\u003e\n\u003cp\u003eThe Baader SolarSpectrum Research Grade 0.4x Telecompressor is an essential optical component designed to solve the primary challenge of high-magnification solar observation: fitting the entire sun in your \u003ca href=\"\/collections\/eyepieces\"\u003eeyepiece\u003c\/a\u003e. Specifically engineered for Solar Spectrum H-alpha filters, which require a slow f\/30 light path, this 2-inch telecompressor reduces your telescope's effective focal length by a factor of 0.4x. This aggressive reduction transforms a narrow, high-power view into a complete portrait of the sun, making the full disk and surrounding prominences visible in eyepieces with focal lengths from 30mm to 35mm.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCapture the Full Solar Disk: A 0.4x Focal Reduction for f\/30 Systems\u003c\/h3\u003e\n\u003cp\u003eBaader's Solar Spectrum H-alpha filters achieve their ultra-narrow bandpass by operating within a parallel light beam, typically created by a telecentric system that extends a telescope's focal ratio to f\/30. While optically necessary, this long effective focal length often results in a field of view too small to contain the entire solar disk. The 0.4x Telecompressor directly corrects this by converting the f\/30 beam to an effective f\/12, dramatically widening your field of view and ensuring you can frame the sun in its entirety.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e2-Inch Format for H-alpha Imaging: Wider Fields and Shorter Exposures\u003c\/h3\u003e\n\u003cp\u003eFor solar imagers, the benefits of the 0.4x telecompressor are twofold.

It is the definitive choice for imagers wanting to capture full-disk portraits, for visual observers using long focal length telescopes, or for anyone operating under seeing conditions that don't support very high magnification.

The SunDancer II comes only with the TZ-3S; for faster telescopes of about f\/7.5 there is the TZ-4S (#1363080), into which the blocking filter of the SunDancer II is moved.

requires, and gives f\/30 on telescopes with f\/7.5. Baader designed it for the SunDancer II H-alpha filter, where it replaces the original 3x telecentric so the filter can be used on telescopes of f\/7 to f\/8. It illuminates a 36 mm image circle at 97 mm from the base of the T-2 thread, has a violet anodized label and weighs 0.25 kg. It does not include the 2 nm blocking filter, which must be moved over from the SunDancer II's TZ-3S.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eWhy H-alpha Etalons Need a Telecentric\u003c\/h3\u003e\n\u003cp\u003eThe 1\/100 lambda plane-parallel etalon in an H-alpha filter requires a perfectly parallelised beam of light over the entire image, and for H-alpha observation below 1 Ångström half-bandwidth (FWHM) a telecentric lens system is absolutely mandatory to reach the recommended focal ratio of f\/30 to (preferably) f\/40.

The TZ-4S replaces it so that the filter can be used at about f\/30 on telescopes of f\/7 to f\/8.

solve the frustrating problem of Newton's rings in solar imaging. It replaces slow, difficult adjustments with a fast, convenient control system, allowing you to achieve a clean image in bright sunlight without fumbling with tiny bolts. This patented tilter uses a simple two-screw mechanism to provide a wide adjustment range of around ±9 degrees, making it possible to remove interference patterns in as little as 5 seconds.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSolar Fast Tilter: Eliminate Newton's Rings in 5 Seconds\u003c\/h3\u003e\n\u003cp\u003eAdjusting a traditional \u003ca href=\"\/collections\/rotators-and-tilt-adjusters\"\u003etilt plate\u003c\/a\u003e in the bright sun can be a tedious process, requiring you to manipulate tiny bolts while trying to see the effect on screen.
