It attaches your camera directly to the telescope through a T-Ring (sold separately), or through the Extender TOA when you need additional focal length.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is what you need if you own a TOA-130 and want to shoot with a DSLR or 35mm film body directly on the telescope, with the field corrected for a flat frame.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eCombining the flattener and T-mount interface into a single part removes one connection point from the imaging train compared with fitting a separate flattener and T-ring adapter — fewer joints to seat correctly, and one less place for the stack to drift out of square. The flattener element corrects the field curvature the TOA-130's triplet objective otherwise produces at prime focus.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDSLR and 35mm film astrophotography on the TOA-130\u003c\/strong\u003e at prime focus, corrected for field curvature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtending the setup\u003c\/strong\u003e with the Extender TOA when a longer focal length is wanted for the same camera.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eA camera-specific T-Ring is required and sold separately — the TOA130FN provides the T-mount interface, not the camera-side bayonet.
