ASKAR 18mm Focal Plane Adjuster High Quality Accessory for Astronomical Telescope Focuser or Camera Sensor
Description:
- In daily astrophotography, users often experience unsatisfactory image results due to the focuser or camera sensor is not 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 wilder 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 some of the telescopes of Sharpstar Optics. 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.
- The Askar Focal Plane Adjuster offers an angle adjustment range of ±1° and is printed with 5′each scale for easy adjustment.
Package Included:
- 1 x Focal Plane Adjuster
- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
