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.
Another Saturday night and I'm up at the winery again with the Santa Cruz astronomy club, and it's looking like it's going to be a good night. Venus and Jupiter are already shining bright above the sunset in the west and despite the coast being covered in fog, at our elevation things look clear.
Tonight I will be hunting for globular clusters. To start things off I've observed M4: a bright globular in Scorpius that is popular and easy to find due to it's proximity to Antares (which I learned tonight means Mars' red rival). It's a good looking globular, but I'm excited to continue the hunt for some more elusive targets in Ophiuchus.
