Introducing the ASKAR ±2 mm backfocus adjuster

ASKAR has developed a backfocus adjuster specially designed to solve backfocus distance problems. This adjuster makes it easy to correct backfocus variations without having to replace or modify expensive components. Thanks to its ingenious design, it enables fine, precise adjustment, with an adjustment range of ±2 mm, which is ideal for compensating for small variations and ensuring perfect focus.

Technical description and features

  • Two versions are available: ASKAR offers two specifications for this backfocus adjuster, one with a camera-side adapter in M54 and the other in M48. This allows users to choose the version best suited to their equipment.
  • Dimensions : The adjuster is 18 mm thick (±2 mm adjustment), offering sufficient stability and robustness for outdoor use. The outside diameter is 74 mm, and it is available with female threads for the telescope interface (M54 or M48) and male threads for the camera interface.
  • CNC precision and printed scale : Manufactured with CNC precision, each adjuster enables backfocus correction to an accuracy of 0.05 mm. What's more, the scale printed on the surface of the adjuster facilitates adjustment and enables the chosen position to be retained. This is particularly useful for users who frequently change equipment.
  • Easy to use : The ASKAR backfocus adjuster is easily attached between telescope and camera. Simply turn the adjuster to adjust the backfocus distance, allowing rapid adaptation to variations. The two screw holes ensure that the adjuster stays in place once the ideal position has been found.

In a nutshell

The ASKAR backfocus adjuster is a practical and effective solution for astrophotographers looking to optimize their focus without complications. Its sturdy design, easy-to-read scale and precise adjustment capability make it an ideal choice for amateurs and professional astronomers alike. This accessory guarantees that your images will always be perfectly sharp, even with a variety of equipment configurations.
