The following form will generate a PDF finder chart suitable for printing using to locate objects in the sky with your telescope!
The Date is only really useful for solar system objects, as deep space objects move measurably only on a galactic timescale.
The larger the F.O.V (field of view), the more "zoomed out" the object will appear. It can be helpful to print several charts of the same object with different field of views.
Limiting the magnitude (remember, lower magnitude means brighter!) of stars and objects can make sure your chart is not cluttered with dim objects that you may not be visible to you anyway. The defaults are good, but try experimenting with raising and lowering the values.
Had to stop and take a break to reapply mosquito repellent, then resumed my search for this pair located in Ophiuchus. I managed to pass right over the dimmer M12 when I found M10, which caused some confusion, but I eventually got it figured out. Very pretty, yet another reason to invest in binocs, I'd love to see them both at the same time.
By now things have started to get dewey. It's still warm out and the skies are still clear, so observation will continue on.
This is a very large globular cluster just north of M10. It doesn't have many surrounding resolvable stars as it's companion, but it makes up for that in sheer angular size. Nice bright spot in the sky.
