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.

The famous Double Cluster was spectacular this evening. Caught it before the moonrise and was able to fit both NGC869 and NGC884 into a single field of view with a 24mm 82deg EP. Spent a long while just soaking in the view. Burnham's description of "one of the truly classic examples of a galactic cluster, and a wonderfully beautiful object for a moderate telescope." is spot on!
The field is full of diamond dust, interesting colors and textures, and small asterisms popping into view the longer you look.
Of note are the red giants in NGC884!

Clear and beautiful sky while I walked the dogs before going to bed. Quickly went inside to grab the binoculars to have a look at the always impressive Perseus Double Cluster.
