Askar 130PHQ review

With the 130PHQ, Askar has consistently continued its series and launched another outstanding flat-field astrograph.
Like the smaller models, the Askar 130PHQ features a field of view already corrected for astrophotography, suitable for sensors up to 60mm diagonal. This allows the 130PHQ to deliver a field of view corrected well beyond full-frame sensors.
The appropriate adaptation of various threads is provided ex works; cameras and dedicated astro cameras can be directly attached via common M54 and M48 threads, for example.
No defined distance is required. As soon as the camera is in focus, the field of view is already corrected thanks to the built-in flattener.
Even when adding an additional filter or other optically effective elements, no distance adjustment is required; only the focus needs to be readjusted.
The PHQ series is aimed directly at astrophotographers among stargazers, but also offers all the necessary features for visual observation.
With an aperture ratio of f/7.7 and a focal length of 1000mm, the Askar 130PHQ is particularly suitable for photographing galaxies or smaller objects, such as planetary nebulae, even on smaller sensors, enabling the capture of fine details.
The optional x0.7 reducer shortens the focal length to 700mm with an aperture ratio of approximately f/5.4. This makes the galaxy hunter capable of photographing larger nebulae, for example. The field of view remains corrected up to full-frame sensors, but a fixed distance from the reducer must be maintained. The required distances to the respective threads can be found in the images in the product description.
