Hey H0ughy

Well done, looks like it does a good job from the flat field you posted. Nice idea using the LED light chain, should help with an even distribution of light inside the box.

Make sure that no direct light falls onto the OTA opening; you only want reflected light from the upper walls and top of the box which should be quite even. I fitted an internal baffle at the OTA end slightly higher than the top of the LED’s so no LED can shine on the aperture.

Cheers

Dennis
