@Tygh Skittish,.... explained.
No more so than in broad daylight. But they do display an awareness to the light. But it is far from being a deal breaker.
I need to run the lamp at perhaps 4/10, 5/10, and at some depth. The depth helps distribute the light more evenly.
In my instance, I need to run it low, due to overhanging shrub branches, which if the light is too high, it casts weird shadows. So, I run it at perhaps 2' high, and 10' out away from the Gallery floor, and 15' from the backstop, with its base-stem placed in a 1" pvc pipe riser that is placed vertically in a one gallon nursery pot that is filled with gravel. This allows for different placements, which has been helpful in figuring this out.
My scope likes it better with less magnification. I run it to a point where it stabilizes, and doesn't cause weird occularities. The scope is 4->7 power, and it likes it at about 5
One thing for sure, is that the rodents are really sketchy, so silence and as little motion as possible.
This is my present placement, with the backstop in the distance in the sun.
This pic shows some of my placement experiments, at least riser locations.
There are two vertical risers attached to the welded wire fence (cat fence to protect the birds that Sarge feeds). There is also a piece of pipe clamped to my rain gutter. These three were either too close, or cast weird shadows.
View attachment 493584 This is my present location, at the base of the rain gutter above, on its catchment wall; but on the next course taller, and slightly wider than this image shows (by inches); Where the orange extension cord end is, is where the light is at present:
View attachment 493583 This location is below the overhanging shrub branch to the right.
That right side, under the branch, is where they'll commonly emerge from. So I don't want to mess with it.
