This reducer is engineered for cameras with a 17.5mm backfocus, or 12.5mm in combination with a 5mm spacer, ensuring correct spacing for a wide range of dedicated imaging cameras.\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\u003e0.6x Focal Reduction: Capture the Full Solar Disc\u003c\/h3\u003e\n\u003cp\u003eBy reducing your imaging system's effective focal length, this 0.6x reducer allows cameras with smaller sensors to capture the entire solar disc in a single frame. The reduction also brightens the image significantly, cutting exposure times to approximately one-third of their original duration. This speed is critical for \"freezing\" moments of steady atmospheric seeing, allowing you to capture sharper, more detailed images of solar granulation and surface features.\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\u003eIntegrated Tilt Control: Eliminate Interference Fringes\u003c\/h3\u003e\n\u003cp\u003eInterference fringes, or Newton's Rings, are a common artifact in solar imaging caused by the highly parallel light path in a filtered system. The Daystar 0.60X Tilt Reducer incorporates a precise tilt mechanism that allows you to make fine adjustments to the optical path. This subtle tilt cancels out the internal reflections that cause fringes, resulting in clean, high-contrast images without post-processing headaches.\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\u003e17.5mm \u0026amp; 12.5mm Backfocus: Engineered for the Combo Quark\u003c\/h3\u003e\n\u003cp\u003eThis reducer is mechanically optimized for use with the Daystar Combo Quark Hydrogen Alpha Filter. It is designed for direct connection to cameras that have a 17.5mm backfocus distance. For cameras requiring less distance, the system also supports a 12.5mm backfocus when used in combination with a 5mm spacer, providing the flexibility needed to integrate with various popular solar imaging setups.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main purpose of the Daystar 0.60X Tilt Reducer?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Daystar 0.60X Tilt Reducer has two primary functions. First, it reduces your telescope's focal length by a factor of \u003cstrong\u003e0.6x\u003c\/strong\u003e, allowing you to fit the entire sun onto a smaller camera sensor. Second, its integrated \u003cstrong\u003etilt mechanism\u003c\/strong\u003e is used to eliminate interference fringes (Newton's Rings) for cleaner, higher-contrast solar images.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the Daystar 0.60X Tilt Reducer let my small-chip camera see the full solar disc with a Daystar Combo Quark?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, that is its primary design goal. Many telescope and camera combinations have too much focal length to view the entire sun at once.

This adjustment changes the path of light just enough to cancel out the internal reflections between parallel optical surfaces that cause interference patterns. By fine-tuning the tilt, you can make these distracting fringes disappear from your image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat backfocus do I need for the Daystar 0.60X Tilt Reducer?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe reducer is designed for two common backfocus standards.
