accommodates the following accessories when attached to the APO140FL F/7; Tube Rings, 9” Dovetail Plate, 9″ Carrying Handle, a Finderscope,
a 2” AP Diagonal, and up to five 2” eyepieces. The dimensions for the TEC hard Case for the TEC APO140Fl are as follows; 36x13x10.

Owing homage to one of TEC’s earliest designs, the APO140ED, the APO140FL F/7debuted in 2017 and has quickly become TEC’s most popular model.

• The APO140FL F/7 features an oil-spaced apochromatic-triplet objective with a Fluorite (CaF₂) middle element, resulting in color correction that is optimized for visual use and imaging. This oil-spaced triplet design in combination with multi-layer coatings on all surfaces of the objective ensure maximal light transmission.
• The objective is housed in an aluminum cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
• The optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation – after the scope leaves TEC, no adjustment is required.
• Further, the crisp all white assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color out of this compact and timeless design.
• Each APO140FL F/7 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments’ largest rotating focuser with coarse and fine focusing 9:1 Planetary Reduction Assembly.

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and TEC then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach TEC's expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

Produced in house, the Field Reducer Corrector, flattens the field of telescopic viewing and reduces the focal ratio by .9x: decreasing it from F/7 to F/6.3. Compared to a Field Flattener, the FRC will have small vignetting in the corners of FOW (~10%). Designed to cover an image circle ø 51mm, or 36x36mm, the FRC has a back focus extension of 115mm, making it perfect for deep space astro-photography. The FRC is available for all models and fits with the FTF#3545 Starlight Focuser. Available for use with all TEC Telescopes. Please specify the telescope to be used with the FRC when the order is placed.

Additional information

Additional Features

Built-in cable management

• USB hub (4 ports)
• 1mm Power port (3 ports)
• Shutter release port
• Auto guiding port
• The CQ350 features built-in cable management. This removes cable drag from hanging cables and reduces the risk of cables getting caught during imaging session. This capability also improves the mounts capabilities for remote use.

The built-in USB hub allows you to simply plug in your camera, guider, filter wheel and other USB accessories into the hub below the saddle plate and connect them using a single USB cable plugged into the rear of the mount. No more tangled mess of cabled hanging or need for multiple cables running around the mount.

Another addition to the cable management system is the three built-in 2.1mm ports situated next to the USB hub. This allows your accessories to also be powered through the mount. This reduces the need for multiple power adapters and other accessories. The ports can be run off of a single power source providing a cleaner set up and less cables.

On the gear of the saddle are three serial ports for various accessories such as ST4 guide cables and other serial based accessories. Like the rest of the cable management this reduces the hanging cables and provide a neat connection to the mount.

Home Positioning

The CQ350 features Automatic identification initial positioning, allowing for observatory customization.

Motors

Advanced Drive mode between worm gear and motor: synchronous wheel and synchronous belt.

PC Direct Connect

CQ350 also feature the new PC direct connect feature. Now you can easily connect your mount to your computer without the need of a hand controller. When paired with the SynScan Pro app. for Windows the mount can be aligned and controlled direct from a PC. This makes imaging refined and easier, especially for those with permanent set ups.

Optional Tripod

Please note this doesn't include a tripod. A suggestion is the Sky-Watcher tripod designed for this mount.

• Rigid steel tube leg tripod with eyepiece tray – suits CQ350 mount heads
• Sky-Watcher / Synta sturdy steel extendable tube leg tripod
• Includes locking centre bolt with eyepiece tray.
