Product Description
In daily astrophotography, users often experience unsatisfactory image results due to the focuser or camera sensor not being flat. As sensor sizes increase, the need for greater precision in adjustments increases. Users need to ensure the focal plane is perpendicular to the optical axis of the system.
The Askar focal plane adjuster helps make precise adjustments to the tilt of the focuser or camera sensor, improving image quality.
Currently, most common focal plane adjusters use a three-point push-pull mechanism. While adjusting the tilted angle, the relative distance between the two ends changes, which will affect the back focus, thus impacting the star quality at the edges of the image.The Askar focal plane adjuster uses a unique spherical adjustment design. This method adjusts the tilt angle without affecting the relative distance, ensuring more accurate and consistent adjustments.
The Askar Focal Plane Adjuster is simple to use, with no need for additional tools, and it also eliminates the need for repeated disassembly and adjustment when attaching a camera or other required accessory. Just rotate the handle to adjust the tilt angle for added convenience.
The Askar Focal Plane Adjuster front thread is a female M54 and the rear thread is a male M48. The package includes an M54 to M48 adapter to convert the front M54 thread to the M48 thread without affecting the overall thickness, offering a wider range of use.
The overall thickness of the Askar focal plane adjuster is 18mm, which is the same as the thickness of the M48 filter threaded ring at the rear end of the reducer of other Sharpstar telescopes. Users with specific Sharpstar telescopes (e.g. APO series, ASKAR V, 71F, 50EDPH) can directly replace the filter thread ring with the Askar Focal Plane Adjuster without recalculating the back focus.
