hi Ken,

I think the problem is that the moon offers even illumination in the whole fov but the plantes are so small that they are permanently overexposed.

Now I am thinking of 2 options:

1: use a ND filter or deep red to compensate the brightness against the background

2: add a 2x + 5x barlow to the optical train to narrow the field, slow down the f ration and magnify more - but I think the resolution of the 6" is somewhat limited at 7.5m fl

what is your opinion?
