I use my Taks during the daytime a lot, some good targets are moss and bark on branches, ants and other insects in trees, ( birds are hard to target unless you have a good alt-az) and leaf vein structures
One to two hundred feet is a good distance for these targets ( I like to read the vin number plate on my neighbor's truck at about 150 ft once in a while), although four to five hundred feet is doable but with some loss of comparative detail, I found that bark and moss give good indications of your optics as they usually have some hard edges with sunlight/shadow shading visible.
About 50-100x is a good daylight range. Have fun with it, I keep a couple of scopes set up in the house and for quick looks, just remove a window screen and open the window.
PS This reminds me of a day when I was using my 12" Meade LX200 from inside the house,to read insulators and the printing on phone company cables on poles about 600 ft away, I started to observe a black bird sitting on a phone cable and at that distance my FOV was restricted to half the bird (either feet or head) when I looked at his feet, the bird was at ease and stayed put but,when I looked at his head he turned his head so one eye faced me, got a worried look and moved down the wire until he was out of the scope's FOV, this happened four or five times and convinced me he could see me looking at him, maybe he saw a 12" eyeball ? and freaked out?
PPS here is a pic with my FS128/Leica zoom shot with a IPhone at 140ft (its not perfect its harder than it looks to hold the phone at the right place without a bracket).
I was trying to photograph an ant on that branch ( the branch is about twice as wide as the length on an ant), never got him to stay in view while I snapped a pic.
