The Founder optics Universal 1x flattener provides correction to all refractors F/5 to F/7 for a flat field and sharp, pinpoint stars in your images. 

Included with the flattener are interchangeable M42 and M48 adapters for maximum compatibility with your imaging system. On the telescope side, the flattener is a push fit 2" that is threaded to accept all standard 2" filters, such as light pollution narrowband filters.

This fully multi-coated flattener has a clear aperture of 38mm.
The image circle at the standard 55mm backfocus distance is 42mm, ensuring full frame sensors are 98% illuminated.

A 0.8x flattener/reducer is also available here.

Please note: Because of the universal nature of this flattener, the quality of the correction will vary from instrument to instrument, resulting in certain amount of egg shaped stars in the corners. This is the case will all universal flatteners.
