Its modular design, based on<br \/>\nthe system <strong>Baader T-2<\/strong> allows it to be easily adapted to different telescopes,<br \/>\neyepieces, astronomical cameras, and SLR or mirrorless cameras.<\/p>\n<p>Its apochromatic optics provide a magnification of approximately <strong>2x<\/strong><br \/>\nwhile minimizing chromatic aberrations and maintaining excellent image sharpness.<br \/>\nIt is particularly well-suited for lunar and solar imaging (with an appropriate filter) as well as planetary imaging<br \/>\nand for compact subjects that require a longer focal length.<\/p>\n<h3>High-quality optical design<\/h3>\n<p>The optical design of the Baader VIP was developed by Dr. Pudenz, who is also known for his<br \/>\nbased on the Zeiss Abbe eyepieces, then adapted by Roland Christen. It was calculated for<br \/>\ncover a diagonal of the image corresponding to the 24 \u00d7 36 mm photographic format.<\/p>\n<p>The lens features a multi-layer anti-reflective coating designed to improve light transmission<br \/>\nbrightness and reduce internal reflections. It can therefore be used with cameras<br \/>\nfull-frame, APS-C, or Micro Four Thirds, as well as with astronomical cameras.<\/p>\n<h3>T-2 Modular System<\/h3>\n<p>The Baader VIP features a fully modular design. Its various components can<br \/>\ncan be assembled or removed depending on the intended use. In particular, it features a connection<br \/>\nstandard photographic <strong>T-2, M42 \u00d7 0.75<\/strong>.<\/p>\n<p>T-2 extension tubes can be placed between the Barlow lens and the camera so that<br \/>\nto increase the working distance. The greater this distance, the greater the factor<br \/>\nThe magnification increases. The Barlow lens can therefore be used at approximately 2x or at a magnification of<br \/>\nhigher, depending on the configuration selected.<\/p>\n<h3>How do I connect a camera to the Baader VIP?<\/h3>\n<p>To connect an SLR or mirrorless camera, you need to use a<br \/>\n<strong>T-2 ring compatible with the camera body<\/strong>. This ring replaces the lens<br \/>\nphotographic and allows the camera body to be connected directly to the Barlow's T-2 thread.<\/p>\n<ol>\n<li><strong>Remove the lens from the camera.<\/strong><\/li>\n<li><strong>Install a T-2 ring that fits the camera body mount<\/strong>, for example, a<br \/>\nT-2 adapter ring for Sony E, Canon RF, Canon EF, Nikon Z, Nikon F, Fujifilm X, or another mount.<\/li>\n<li><strong>Screw the T-2 ring onto the M42 \u00d7 0.75 thread of the Baader VIP.<\/strong><br \/>\nThe connection is entirely mechanical: no camera lens is used.<\/li>\n<li><strong>Next, insert the Barlow lens into the telescope's eyepiece holder<\/strong> by using<br \/>\nits 1.25-inch flow path or its 2-inch configuration, depending on the chosen setup.<\/li>\n<li>Position the camera correctly, then carefully tighten the screws or the ring<br \/>\nTightening the eyepiece holder.<\/li>\n<li>Focus the telescope using its focusing system.<\/li>\n<\/ol>\n<p>The standard photo layout is therefore as follows:<\/p>\n<p><strong><br \/>\nTelescope \u2192 Baader VIP \u2192 T-2 thread \u2192 T-2 adapter ring \u2192 camera without a lens<br \/>\n<\/strong><\/p>\n<p>In this setup, no eyepiece is placed between the Barlow lens and the camera.<br \/>\nThis is a close-up photograph taken with a Barlow lens, not a<br \/>\nviewing through an eyepiece.<\/p>\n<h3>Choosing the Right T-2 Ring<\/h3>\n<p>The required adapter ring depends entirely on the camera mount. An adapter ring designed for<br \/>\nA Canon lens cannot be used on a Sony or Nikon camera. It is therefore important<br \/>\nto select a ring that indicates both:<\/p>\n<ul>\n<li>the exact camera mount; ;<\/li>\n<li>an Astronomical T-2 connector with an M42 \u00d7 0.75 thread.<\/li>\n<\/ul>\n<p>The astronomical thread should not be confused with <strong>T-2 M42 \u00d7 0.75<\/strong> with the former<br \/>\nphotographic threading <strong>M42 \u00d7 1<\/strong>. Although their diameters are the same, their pitches<br \/>\nThe screw is different.<\/p>\n<h3>Adjusting the Gain Factor<\/h3>\n<p>The reported factor of approximately 2x depends on the distance between the optical element and the Barlow lens of the<br \/>\nsensor. Adding T-2 extension tubes increases this distance and allows for a<br \/>\nsuperior amplification.<\/p>\n<p>A higher magnification produces a larger image on the sensor, but<br \/>\nIt also reduces brightness, increases the required exposure time, and thus makes tracking<br \/>\nthan more demanding setups. To start with, it\u2019s generally best to use the<br \/>\nstandard configuration close to 2x.<\/p>\n<h3>Compatibility<\/h3>\n<ul>\n<li>SLR and mirrorless cameras with a compatible T-2 ring<\/li>\n<li>Astronomical cameras equipped with a T-2 thread<\/li>\n<li>1.25\u2033 and 2\u2033 Eyepiece Holders<\/li>\n<li>Astronomical Eyepieces for Visual Observation<\/li>\n<li>Extension Tubes and Accessories for the Baader T-2 System<\/li>\n<li>Full-frame, APS-C, Micro Four Thirds, and smaller astronomical sensors<\/li>\n<\/ul>\n<h3>Key features<\/h3>\n<ul>\n<li>Gain factor: approximately 2x, adjustable with T-2 extensions<\/li>\n<li>Focal length of the Barlow lens: -65.5 mm<\/li>\n<li>Optical design with apochromatic characteristics<\/li>\n<li>Multilayer anti-reflective coating<\/li>\n<li>Photographic adapter: T-2, M42 \u00d7 0.75<\/li>\n<li>Compatible with 1.25-inch and 2-inch eyepiece holders<\/li>\n<li>Aperture: 28 mm<\/li>\n<li>Designed to cover a 35 mm photographic diagonal<\/li>\n<li>Modular structure for visual and photographic use<\/li>\n<\/ul>\n<h3>Recommended applications<\/h3>\n<p>The Baader VIP is particularly well-suited for photographing the Moon, the planets, and fine details<br \/>\nsolar systems with an appropriate solar filtration system, binary stars, and objects<br \/>\ncompact cameras.
