1.10x Field Flattener for 110mm f/6 StarFire GTX (110FF)
- SKU:
- 110FF
Designed for: 110mm f/6 StarFire GTX
Application: Ideal for digital imaging with DSLR and CMOS cameras.
This optimized design uses two matched glass elements assembled into an air-spaced assembly to produce an F/6.65 photographic speed. The Flattener design produces sharp diffraction-limited detail over a 35mm full-frame format. All mechanical parts, including the covers, are beautifully machined anodized aluminum with a lustrous black finish. The barrel design uses a unique dovetail for quick attachment to the focuser without introducing tilt into the optical system.
The 110GTX operating at f/6.65 (1.10x magnification) will capture extreme detail with the full format CMOS cameras currently popular amongst astro-imagers. This accessory is a must for fastidious astro-imagers, as the 110FF provides an extended color correction range far beyond the visible range, producing high-resolution images from the latest technology in CMOS sensors. Wide-field images will be highly detailed which allows the astro-imager to make very large prints without doing time-consuming mosaics.
The 110FF fully illuminates a 60mm circle.
Included
- Field flattener housing with optics optimized for the 110GTX
- Two beautifully machined and anodized covers
Back-focus spacing from the rear flange
- Back-focus distance is 95.5mm - measured from the back flange to the camera sensor.
- Back-focus distance with the optional EXT327-14.7 is 80.8mm. We offer adapters for popular CMOS as well as Nikon and Canon DSLR and mirrorless cameras based on this distance. These adapters are described below.
Use with CMOS Cameras up to 35mm
Adapters are available for use with CMOS cameras with thread sizes of 42, 48, 54 and 68mm. These are designed for the popular CMOS cameras currently available that utilize the 55 mm standard spacing. The EXT327-14.7 Back-focus Spacer is required for this image train. Refer to the 110GTX CMOS System Diagram.
