Sighting problem

Mounted the scope in low light in the basement and had mounted it canted 90degrees so was adjusting the up down instead of left right. Couldn't see markings well in low light as I have perfect above 20/20 in normal light but some retinal scarring which causes low light vision issue. Sorted now. Only about 10yards in my basement rested on back of a chair crouching but impressed at the groups
