The tilter allows you to make fine angular adjustments to square the sensor to the optical axis, ensuring sharp stars across the entire frame.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhere should I place the T-2 Tilter in my imaging setup?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFor best results, the T-2 Tilter should be placed as close to the camera sensor as possible. The ideal location is typically right before the camera body, after any filter wheels, filter drawers, or off-axis guiders. This ensures that you are adjusting the camera sensor itself relative to the corrected optical path.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the T-2 Tilter necessary for my 8\" f\/10 SCT?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWhile any system can exhibit tilt, it is most pronounced in \"fast\" optical systems (typically f\/5.5 or faster). An f\/10 Schmidt-Cassegrain has a more forgiving depth of focus, so minor tilt may not be visible. However, if you are using a focal reducer that brings your system to f\/7 or f\/6.3, or if you notice persistent, one-sided star elongation, the T-2 Tilter can be a valuable tool for achieving perfect correction.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I know how much to adjust the T-2 Tilter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAdjusting a tilter is an iterative process. You start by taking a short exposure of a dense star field. Analyze the image to see which corner or edge has the most elongated stars. You then make a small adjustment to the tilter to \"push\" the sensor plane in that direction. Take another test image and repeat the process until stars are uniformly round across the entire field. Software tools like N.I.N.A.'s Aberration Inspector can make this process much faster.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the T-2 Tilter correct for coma or field curvature?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo. The T-2 Tilter is a mechanical adjuster and corrects only for sensor tilt.
