This OTA is based on the FSQ-104ED Petzval Quadruplet OTA but with a fresher 4" heavy duty focuser and in built camera angle adjuster making it perfect for all imaging applications. This model comes as an OTA only. No accessories are included. There is a version available with all standard accessories included. The code for this model is TQE10640.

The same high quality petzval quadruplet optical design of the FSQ-106ED but with a larger heavy duty 4" focuser with in built camera angle adjuster. This will lift up to 11 lbs in weight and hold it still, making any visual or imaging set up possible.

The tube also features a 10:1 microfocuser for fine adjustments whilst the CAA maintains focus. The highest quality of build and optical performance in this compact 106mm OTA.

The FSQ-106EDX4 boasts a massive 178mm of back focus to accomodate accessories such as flip mirrors, filter wheels and other imaging accessories.

The astrophotographers see in the FSQ-106ED one of the best astrographs available for the amateur astronomers. With its focal length of 530mm, an image circle of 88mm and a photographic field of 9,5°, it acts as teleobjective for most powerful CCD and DSR/DSLR cameras of the market.

Based on a Petzval quadruplet optical design with apochromatic ED glasses, the FSQ-106ED is optimized for wide-field imaging of the deep sky. It offers a flat field, and comes equiped with a built-in camera angle adjuster and an oversized rack-and-pinion focuser. To minimize the size of the optical tube, it includes a retractable dewshield and an important backfocus.

The modified Petzval design of the FSQ-106ED, with the field flattener integrated inside the tube, makes it possible to cover all the photographic formats, from 35mm SLR/DSLR to 6x7 cameras. Its photographic image circle of 88mm of diameter (field of 9,5°) does not have an equivalent on the market of the refractors of 100mm of aperture. CCD users will be able to dream with the use of large sensors without risk of vignetting or loss of definition in edge of field. As it is the tradition inside Takahashi company, the objective is entirely collimatable in order to compensate for the possible mechanical and thermal stresses. A perfect image is at this price.
