Up early to go to the Edward Tufte course and saw Mercury, Venus, Mars Saturn and Jupiter all in the sky at once. Fantastic!

No detail at 200x but un unmistakeable red/orange disk.

Finally hauled myself out of bed early enough to go check out the two planets I hadn't seen through my telescope: Mars and Mercury. Mars was a gorgeous rust-colored ball, it's two moons clearly visible.

I couldn't get up early enough to get out my telescope but it was still an amazing site to see red/orange Mars, Jupiter and bright Venus so close to each other!

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.
