It adds the LFPT internal double stack module (LS152 version) to the same components as the LS152THa Standard Kit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 100% unobstructed system will perform to the highest level at both low and high magnifications. Utilizing both advanced high-contrast coatings and the Doppler True Pressure Tuning system, you will be able to experience crisp, sharp, high magnification visual images, as well as use this system for high end digital processes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAn unobstructed internal HD etalon with the pressure tuner allows for a bandpass of \u0026lt;0.45Å, providing slightly higher surface detail without the loss of edge detail. The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat You'll See\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTrue Doppler Tuning allows for a shift into and away from you, adding a 3D-like component to the viewing experience. While it has minimal effect on prominences due to their location at the edge of the disk, it does have an effect on filaments and active regions on the surface.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhile looking at a filament at the center of the Sun, you can Doppler shift from the base of the filament to the tip, following the filament through its structure toward you and away from you. This allows for enhanced visual and imaging capability for the observer, as well as a research tool for the avid hobbyist.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLS152THa OTA w\/ H-alpha module: 152mm aperture, 900mm f\/6 refractor.
