The Askar 1x Field Flattener for 140APO is a specialized optical accessory designed to enhance the imaging performance of the Askar 140APO telescope. This field flattener corrects for field curvature, ensuring sharp, well-defined stars across the entire field of view, particularly at the edges of the image where curvature effects are most pronounced.
Specifically designed for use with the Askar 140APO telescope. Ensure compatibility with your camera sensor size before purchase.
Optical Performance
The 1x Field Flattener features high-quality optics designed to correct for field curvature without altering the focal length of the telescope. This means you maintain the native focal length and f-ratio of your 140APO while achieving flat, distortion-free images across the entire field, even with larger sensors.
Enhanced Imaging Capabilities
By correcting field curvature, this flattener allows for significantly improved edge-to-edge sharpness in your astrophotographs. Stars remain pinpoint across the entire frame, and extended objects retain their shape and detail even at the corners of the image. This is particularly beneficial for wide-field imaging of large nebulae, star fields, and galaxies.
1x Magnification
Unlike focal reducers, this field flattener maintains the original focal length of your telescope. This 1x magnification ensures that you retain the native field of view and f-ratio of your 140APO, preserving its inherent optical characteristics while improving overall image quality.
Construction Quality
Built with high-quality materials and precision-engineered optics, the field flattener is designed to withstand the rigors of frequent use and maintain its optical alignment. The robust construction ensures consistent performance over time, making it a reliable addition to your astrophotography setup.
Easy Integration
Designed specifically for the Askar 140APO, this field flattener ensures seamless integration with your telescope. It likely features standard threads or adapters for attaching to your imaging train, allowing for straightforward installation and removal as needed.
Versatility
While optimized for use with the 140APO, this field flattener can potentially be used with other telescopes of similar focal ratio, though best performance is achieved with its intended telescope. It's suitable for a wide range of astrophotography projects, from wide-field Milky Way shots to detailed images of galaxies and nebulae.
Technical Considerations
- Magnification: 1x (no change to focal length)
- Optimized for: Askar 140APO telescope
- Sensor coverage: Likely optimized for full-frame sensors, but effective with smaller sensors as well
- Backfocus: Refer to manufacturer specifications for optimal camera spacing
