ZWO has created a system where each part is matched to the others, delivering a portable platform for capturing detailed, wide-field images on full-frame cameras without the complexity of traditional setups.\u003c\/p\u003e\n\u003cp\u003eFor the traveling astrophotographer, this package simplifies setup. The telescope's flat-field optics require no external correctors, the mount carries the load without counterweights, and the lightweight tripod ensures stability without bulk. It suits imagers who want strong optical performance and precise tracking in a system that can be easily transported to dark-sky locations and set up quickly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 33 lb. Capacity for a 14.9 lb. Telescope\u003c\/h3\u003e\n\u003cp\u003eThe pairing of the FF110-APO telescope with the AM5N mount is deliberate, creating a system with a significant payload margin for stable, long-exposure imaging. The telescope, fully equipped with its handle, rings, and 300mm Vixen-style dovetail, weighs 14.9 lb. The AM5N mount supports up to 33 lb. without any counterweights.\u003c\/p\u003e\n\u003cp\u003eThis leaves over 18 lb. of additional capacity for your imaging train. You can add a large cooled camera, a filter wheel, an off-axis guider, and a guide camera without approaching the mount's operational limit. This headroom is critical for maintaining tracking accuracy, as it ensures the mount's motors are not strained, resulting in sharper stars and a higher percentage of usable sub-exposures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e110mm f\/7 Quadruplet Optical Design\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the bundle is the FF110-APO's four-element, air-spaced apochromatic optical system. With a 110mm (4.33\") aperture and a 766mm focal length, the f\/7 design strikes a balance between light-gathering power and image scale. The quadruplet lens arrangement, which includes one Extra-Low Dispersion (ED) glass element, corrects for optical aberrations across the visual spectrum.\u003c\/p\u003e\n\u003cp\u003eThe ED element is key to minimizing chromatic aberration, virtually eliminating the false color halos around bright stars that can soften an image. This advanced optical design is what allows the telescope to produce sharp, high-contrast views and photographs, making it equally capable for detailed deep-sky imaging and immersive visual observation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Native 44mm Full-Frame Image Circle\u003c\/h3\u003e\n\u003cp\u003eThe FF110-APO is engineered with a built-in field corrector, producing a natively flat 44mm image circle. This is large enough to fully illuminate full-frame (36x24mm) camera sensors, delivering sharp, point-like stars from the center of the frame to the corners without requiring a separate field flattener.\u003c\/p\u003e\n\u003cp\u003eThis integrated design greatly simplifies your imaging setup. There are no complex back-focus calculations or additional spacers to manage. Instead of a single fixed distance, the telescope offers a flexible focus range of 42mm to 73mm from the M48x0.75 thread. This allows you to attach your camera and accessories and begin imaging immediately, saving valuable time under clear skies.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e3\" Focuser and Imaging-Ready Mechanics\u003c\/h3\u003e\n\u003cp\u003eTo handle heavy imaging loads, the FF110-APO is equipped with a rigid 3\" dual-speed rack-and-pinion focuser. This design prevents sag and flexure, even with a large camera and filter wheel attached. The focuser provides 31mm of travel, and a 1:10 fine adjustment knob allows for the precise, minute movements needed to achieve critical focus.\u003c\/p\u003e\n\u003cp\u003eThe telescope's mechanical design is focused on practicality for astrophotography.\n\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e360° Rotator:\u003c\/strong\u003e The entire focuser assembly rotates, allowing you to frame your target without removing the camera.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware:\u003c\/strong\u003e The OTA comes with CNC-machined mounting rings, a carrying handle, and a 300mm Vixen-style dovetail plate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinder Bases:\u003c\/strong\u003e Two findershoes are mounted on the focuser body, providing flexible attachment points for a guide scope and finder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetractable Dew Shield:\u003c\/strong\u003e Helps prevent moisture from forming on the objective and blocks stray light, improving image contrast.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e33 lb. Capacity from a 12.1 lb. Harmonic Mount Head\u003c\/h3\u003e\n\u003cp\u003eThe ZWO AM5N mount uses a strain-wave gear and synchronous belt drive system, a technology that delivers high torque from a very compact and lightweight mechanism. The mount head itself weighs only 12.1 lb. but can carry an imaging rig up to 33 lb. without counterweights. For heavier setups, capacity can be increased to 44.09 lb. with an optional counterweight.\u003c\/p\u003e\n\u003cp\u003eEach mount is factory-tested to ensure a native periodic error of less than ±10 arcseconds over its 288-second cycle, and an individual performance sheet is included. With a 300:1 reduction ratio and a stepper motor resolution of 0.17 arcseconds, the mount makes precise guiding corrections. When moving between targets, it slews at up to 6° per second, minimizing downtime during an imaging session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual-Mode Control from 0° to 90° Latitude\u003c\/h3\u003e\n\u003cp\u003eThe AM5N is engineered for use anywhere on Earth, with a mechanical latitude range of 0° to 90°.

Tripod with 200mm of Safe Clearance\u003c\/h3\u003e\n\u003cp\u003eThe foundation of this bundle is the ZWO TC40 carbon fiber tripod and PE200 pier extension. The TC40 tripod weighs 5.07 lb. but supports a 110.23 lb. load, providing a rigid, vibration-dampening base that is easy to transport. Its height adjusts from 18.5\" to 31.49\", allowing you to achieve a low center of gravity for maximum stability.\u003c\/p\u003e\n\u003cp\u003eThe included PE200 pier extension fits between the tripod and the AM5N mount head, adding exactly 200mm of vertical height. This clearance is essential for preventing the FF110-APO and its attached camera from colliding with the tripod legs when pointing near the zenith or performing an automated meridian flip. The pier is machined from aircraft-grade aluminum to provide this space without introducing flexure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e12V 3A Operation with Power-Off Protection\u003c\/h3\u003e\n\u003cp\u003eThe AM5N mount operates on a standard 12V DC power supply and requires a source capable of delivering at least 3A to ensure stable performance, especially during high-speed slews. If the input voltage drops below 10.8V, the mount will emit an audible alarm to warn of a potential power issue.\u003c\/p\u003e\n\u003cp\u003eA critical safety feature is the mount's power-off protection. In the event of an accidental power loss, a mechanical brake on the Right Ascension axis engages automatically. This prevents the telescope from swinging freely, protecting your optical tube and expensive camera from impact damage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eImaging and Visual Use with the FF110 \u0026amp; AM5N\u003c\/h3\u003e\n\u003cp\u003eThis bundle is optimized for astrophotography. The 766mm focal length and 110mm aperture are an excellent match for a wide range of deep-sky targets, from the core of the Andromeda Galaxy (M31) to smaller planetary nebulae. The native flat-field optics mean you can connect your full-frame or APS-C camera directly to the M48 or M54 threads and start imaging with sharp stars across the field.\u003c\/p\u003e\n\u003cp\u003eWhile designed for imaging, the system is also a superb visual instrument. By adding a 2\" diagonal and eyepieces (sold separately), the apochromatic optics provide high-contrast, color-pure views of the Moon, planets, and bright deep-sky objects. The AM5N's Alt-Az mode simplifies setup for quick visual sessions, making it a versatile platform for any observing goal.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFirst Night Setup: From Box to Sky\u003c\/h3\u003e\n\u003cp\u003eSetting up the bundle is straightforward. Start by extending the TC40 tripod legs and leveling the tripod head. Attach the PE200 pier extension, followed by the AM5N mount head. Set the mount's latitude adjustment to your local latitude. Mount the FF110-APO onto the AM5N's dual saddle using its 300mm Vixen-style dovetail.\u003c\/p\u003e\n\u003cp\u003eBecause the AM5N is a harmonic drive mount, precise balancing is not required for payloads up to 33 lb. Attach your camera, guide scope, and any other accessories. Power on the mount and perform a software-assisted polar alignment using your camera and a program like the ASIAIR app. Once aligned, you can begin slewing to targets and focusing your main camera to start your imaging session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eZWO FF110-APO vs. FF90-APO: Image Scale vs. Portability\u003c\/h3\u003e\n\u003cp\u003eThe primary decision between the FF110-APO and its 90mm sibling involves a trade-off between image scale, light-gathering power, and portability.
