Not useful for telescope pattern ... especially when using an astronomical camera due to very high magnification. Really a tool, not an app, as it just provides an image. Would be much more helpful if you could print it out. Also I don't mind ads but not every time you touch anything.
Good Adding 2 or 3 different chart type can be good. Very useful in many situations. Please the people don't know/understand what this app do, avoid to publicly show off your ignorance on yours comments.
Absolutely brilliant! Always have a focus chart in your pocket :) I can't understand why people moan about this, it works perfectly. Why would you install it if you didn't know what to do with it?
Simple and easy Focus chart; put LG 7" tablet on lightstand; camera on tripod and shot at several different f-stops and ISO settings, good camera/lens check
Works fine. I don't understand why posters would download it if they don't know what it's for.
New charts with higher resolution. Swipe left and right two switch between the two charts.
