A flattener \"levels\" the optical problems in the image field such as coma and astigmatism and leads to a similarly perfect image as on the optical axis itself. The flattener model 1 is especially designed for short focal lengths and faster aperture ratios and currently represents the limit of what is possible.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThere is currently no comparable flattener on the market with such a good apochromatic longitudinal and transverse aberration correction. Other cheaper models, on the other hand, clearly fall behind. This can be seen on the one hand in their significantly higher edge vignetting, but mainly in their drastically larger lateral color errors. This flattener allows a generous working distance from the thread to the focus of over 90mm, see attached file. So that there is space for all common accessories such as filter wheels.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eOur Model 1 is suitable for the following telescopes and telescopes with a similar aperture ratio:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM LZOS Apo 105 F\/6,2\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM Apo 107 F\/6.5\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM LZOS Apo 115 F\/7\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM LZOS Apo 123 F\/6\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM LZOS Apo 130 F\/6\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAPM-Riccardi Apo Doublet 140 F\/7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eCharacteristics\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eUniversal flattener for short focal lenghts and fast f\/ ratios\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eHigh quality triplet optical design\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eState-of-the-art multicoatings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"data-table\" style=\"margin: 0px;
