Lacerta FLATFIELD BOX Flatfield Panel for 6" (150mm) Newtonian Telescopes - Mark II
Lacerta FLATFIELD BOXES have been designed for the three most popular Newtonian telescope sizes, 6", 8" and 10", so that you can achieve a flat, homogenious, equally illuminated field when taking images of the night sky.
Would be compatible with other telescope types as well as long as the size covers the whole aperture of the telescope.
Works from 12 Volts and compatible with the most widespread power supply connector that is used for powering EQ5, HEQ5 and EQ6 mounts with 5.5mm/2.1mm jack power connector.
Available in three sizes. This product listing is for the FFB15Plus - FLATBOX for a 6" Newtonian telescope.
This new version also comes with a round foam cover to save your flatfield box from scratches. Another change in the MARK II series is the improved homogeneity of illumination. See details further below...

Neutral and extremely uniform illumination
The special feature of the flatfield box is that:
- it provides a very color neutral light, so the color channels are equally saturated, and this is the ideal basis for a successful flat.
- Furthermore, the illumination is extremely uniform, even better than the EL films or another FFB, which still have weak variations over the surface
- The LEDs do not flicker in the mains frequency like the EL film, which means that much shorter exposure times can also be used, eg 1 / 100sec.
- The LEDs can be controlled with the optional dimmer or controller, so there is no problem with very sensitive CCD cameras.
Note that you don't have to power your mount when you take flats, so you can use the power supply that comes with your mount or if your mount has got a different power connector (i.e. AZ-EQ5, AZ-EQ6 or EQ8, etc) then you can buy such cable separately:
if you wanted to regulate the brightness of this flatfield box, you'd also need the following accessories:
and one of the RCA to 5.5mm/2.1mm jack cables (15cm, 60cm or 2m version):
