In another post, I put up some points on how I compare scopes. Looked through a bunch and this test really separates the good from the poor. And many times, big price doesn't equate to great glass.
So have a read, look out your window and decide "What can you actually see?"
TESTING SCOPE RESOLUTION EASILY AT HOME....
What I use is a hand railing and chimney on homes over 1000yds away. There is no doubt that the are plenty of straight equally spaced lines and everyone understands what they are looking at.
But in comparing many scopes, my question is always... "what do you actually see?" I have yet to look through a scope that couldn't make out the shape of the chimney or the white lines of the rail.
Where most fail is being able to resolve the grid of these objects. To actually resolve and differentiate the detail that make up these patterns. Some will even bend the image so the objects are curved... which of course they are not.
Here is how the comparision typically go...
So many scopes will see the rectangle that is the chimney, with blotches of colour that are the bricks. Odds of seeing the grout line or anything beyond a multi colour rectangle are slim. If it is a scope, odds are you can see this.
Scopes that many call very good glass, will show the grid that is the grout lines but they are faint. Just a different colour blurry line. There will be the blotches which are the bricks, then a line, then a blotch. In this class, better scopes will give clear colour distinctions from brick to brick and within the brick itself.
Even better will clearly resolve the grout lines so they are sharp and distinct. You can see where they start, end and even if they do not line up with the next line. When highlighted with good light, each brick is clearly resolved in colour with the typical pattern easy to see.
Top tier glass under clear air and good lighting... you can see the texture and shadows in the grout line. Texture, lumps and bumps of the brick. This is the level that my scopes can see.
What do you see?
For top tier glass AND top tier coatings... you can see this even in moderate mirage. There are only 2 scopes I have looked through that can do this.

PS Winter is the best time to try this. For many places, the air is very cold with near zero humidity. This drives out the moisture, dust that causes alot of optical distortion. Just don't open a window on a heated house and look out..... you are just looking through the flood of mirage that is the hot air escaping from your home.
Go outside, and put the scope on a tripod and view.
