That first link is *very* helpful once I enter my own location, especially the section **Comet C/2020 F3 (NEOWISE) rise and set times** which tells me when it rises and sets and provides alt-az coordinates.

I have marked this as the answer because the skylive link allows you to enter your geographic location and get information specific to your location on the globe. Additionally, it provides easy-to-use azimuth and altitude details which are easy to comprehend and interpret with just a compass. I am delighted to report that I saw the comet last night. I was unable to photograph it, but really enjoyed having a look.

I'm guessing that the me-centric coordinates will be a lot more elaborate because of the earth rotating, etc. I.e, the coordinates will change greatly throughout the day -- or even while the comet is visible at morning/night.

<p>I live in Los Angeles and have a camera adapter for my telescope -- nothing fancy just an Astromaster 114. What is the optimal time, in terms of dark sky and bright comet, to take a photo of Comet NEOWISE? I.e., when will it be brightest relative to the surround sky? When will it be largest?</p>
<p>And, lastly, what is the best time tonight to view it?</p>
<p>EDIT: I've spent the last two nights at sunset trying to locate it, but it doesn't really get dark until about an hour after sunset around 8pm.

<https://theskylive.com/c2020f3-info>

The bright start Capella, which is relatively easy to spot, could guide you to the comet.

Now that it has passed the perihelion of its orbit, it is receding from the Sun. So the brightness will gradually drop. Some details that might interest you are here.
