Generate a finder chart

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.

very close to M12. Hard to find without a 9x50 finderscope. good looking globular cluster.

Faint, a small ball of unresolved light fairly unimpressive.

Had to stop and take a break to reapply mosquito repellent (by the way, lemongrass lotion works WONDERS, and lasts about 3 hours in humid/sweaty conditions), 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.

Now I'm getting the hang of it. M10 is a nice medium sized globular cluster with a very nice scattering of stars around the main cluster. They could be foreground or background stars, but they do look very nice. It lies just due south of M12, it's equally pretty companion.
