Comet C/2021 C4 (ATLAS) was about magnitude 18 and 341 million miles from Earth in this image taken above the light pollution and haze of Tucson as it was located low above the southern horizon. The comet has a faint tail to the SSE of the coma. The comet was at perihelion in its orbit this past January and will stay around magnitude 18 for the next few months before slowly fading as it moves away from Earth.
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.
