This fast, wide-field f\/2.2 system allows for shorter exposure times compared to traditional f\/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.\u003c\/p\u003e\n\u003cp\u003eRASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.\u003c\/p\u003e\n\u003cp\u003eToday, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent.\u003c\/p\u003e\n\u003cp\u003eCombine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical Performance\u003c\/strong\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003eThe RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument.

At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.\u003c\/p\u003e\n\u003cp\u003eEngineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly. \u003cspan\u003eThe \u003c\/span\u003e\u003cspan\u003eDovetail CGE bars on the top of the optical tube provides a connection for use of optional accessories like a guidescope.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"table-open\" id=\"product-specs-list\"\u003e\n\u003ctbody id=\"spec-block-1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eRowe-Ackermann Schmidt Astrograph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e279mm (11\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e620mm (24.4\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003ef\/2.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCentral obstruction diameter\u003c\/td\u003e\n\u003ctd\u003e114mm (4.48\") (41% of aperture diameter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Gathering Power (Compared to human eye)\u003c\/td\u003e\n\u003ctd\u003e1588x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution (Rayleigh)\u003c\/td\u003e\n\u003ctd\u003e0.49 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution (Dawes)\u003c\/td\u003e\n\u003ctd\u003e0.41 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage Circle\u003c\/td\u003e\n\u003ctd\u003e43.3mm (1.7\") Ø , 4.0°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUseable field\u003c\/td\u003e\n\u003ctd\u003e52mm (2.04\") Ø , 4.8° only minimal performance loss at edge of FOV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWavelength range\u003c\/td\u003e\n\u003ctd\u003e400 -

This incredibly fast f\/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely.

Instead of a secondary mirror, the Mak features a “secondary spot” of reflective coating applied directly to the inside of the corrector plate.

Also, the secondary spot is significantly smaller than a traditional Schmidt-Cassegrain secondary mirror, giving the Mak its signature high-contrast views.\u003c\/p\u003e\n\u003cp\u003eOne important

Larger rear lens groups absolutely minimize vignetting in formats up to 50mm diagonal. For these large chips an optional field corrector was developed\u003cspan\u003e \u003c\/span\u003eso the corners of the newly brightened edges would virtually be as perfect as the center of the field.\u003c\/p\u003e\n\u003cp\u003eNext, to take full advantage of the larger lenses, they developed a larger focuser and draw tube having a 3\" front aperture and 2.4\" rear aperture. This eliminates any restriction of the larger diameter converging light cone. Tele Vue build and test the rack and pinion focuser to hold 12 lbs. of weight, yet still permit extremely fine focusing control via a 10:1 dual speed pinion assembly. This new draw tube also permits quick change from visual to imaging operation and allows full camera rotation without focus change. In addition, it has the capability to correct for any residual focal plane tilt and accepts a \"position stop\" for our digital micrometer to allow repeatable focus measurement to 0.0001\".\u003c\/p\u003e\n\u003cp\u003eTo maintain squareness to the optical axis while changing camera orientation, the draw tube has three lock screws that tighten against a taper on the \"imaging insert\" ring.

This eliminates any restriction of the larger diameter converging light cone. Tele Vue build and test the rack and pinion focuser to hold 12 lbs. of weight, yet still permit extremely fine focusing control via a 10:1 dual speed pinion assembly. This new draw tube also permits quick change from visual to imaging operation and allows full camera rotation without focus change. In addition, it has the capability to correct for any residual focal plane tilt and accepts a \"position stop\" for our digital micrometer to allow repeatable focus measurement to 0.0001\".\u003c\/p\u003e\n\u003cp\u003eTo maintain squareness to the optical axis while changing camera orientation, the draw tube has three lock screws that tighten against a taper on the \"imaging insert\" ring.

With 4 elements in 3 groups (2-1-1- configuration), the 71 mm RedCat Petzval refractor is designed with a doublet made of FPL-53 glass up front, a single central element, and a single rear lens to provide a flat image plane without any need for an additional flattener.\u003c\/p\u003e\n\u003cp\u003eWilliam Optics designed this refractor with excellent color correction and pinpoint stars, even at the edge of the 45 mm image circle.\u003c\/p\u003e\n\u003ch3\u003eBahtinov Mask\u003c\/h3\u003e\n\u003cp\u003eIncluded with this William Optics RedCat telescope is a Bahtinov focusing mask.
