Universal flat field light panel for two sizes of your choice with integrated Bahtinov mask

Universal flat field light panel for two sizes of your choice in one (max 160mm diameter)

(use the arrows on the left and right sides in the middle of the frame to scroll through pictures)

This flat field light panel is based on an electroluminescent (EL) foil. It is provided with either an additional ND filter foil from Lee Filters or with a grey plexiglass filter to reduce the brightness if needed.

You can use this panel with two telescopes or lenses from one order: one will fit directly, and another will need an adapter which is a part of the order. More adapters can be ordered separately, please contact us. The advantage of this approach is that the panel will sit on the front edge of the telescope or on the lens sun hood and you do not need to hold it. The size of the panel will be selected to fit the larger of the two sizes you specify.

There are two main sizes of panels that are used: a smaller one for tubes of max 130mm diameter and a larger one - max 160mm diameter. If you use smaller telescopes, the smaller version will be a better choice, since it is more compact and less expensive.

The cover of the panel is equipped with an integrated Bahtinov mask. The provided adapter for the secondary size can also be used with the cover to center the mask pattern on the telescope or the lens.

The screenshots in the picture gallery show test results comparing the results from this panel and another, much more expensive panel. Let us know if you see a difference ๐Ÿ˜‰

The panel is powered by 12V DC and uses the standard DC 5.5/2.1mm jack. A 110-220V power supply is included in the package.
