About this product

Model: askar_120_flatt
Part Number: ASKFL12010

This Askar 1.0x flattener does not change the telescope's focal ratio. After connecting to the Askar 120APO, the focal ratio remains F/7.

It corrects field curvature and coma, resulting in flatter field edges and finer star points.

The triplet optical design design provides a 44mm full-frame image circle.

The back focus distance from the M48 thread is a standard 55mm.

The front thread is M84x1.

At the camera end, it is equipped with M54*0.75 and M48*0.75 adapters, which are convenient for connection.

At the same time, it has a built-in M48*0.75 2-inch filter thread, so a 2" filter can be directly installed and used.

Threaded metal caps are provided to prevent dust from entering when not in use.

The overall weight is 0.75kg.
