Loads of you have asked me about how I planned the image with the comet using stellarium, @photopills and google maps, so here goes a thread describing briefly each step. I hope you enjoy it 👇🏼
1.- in stellarium go to configuration, plugins-> Solar System Editor.
Hit configure & select comets and download lost of objects. Here you can select from the drop down menu or put the URL of the minor planet database website.
Finally, import all the orbital elements 👇🏼
2.- This will update existing comets and add new ones like #cometNEOWISE.
Now that you have it in Stellarium, search for it using its real technical name: C/2020 F3 👇🏼
3.- From all the info that Stellarium gives you, you want to know the Azimut (Az, which tells you how far north it is), and the Altitude (Alt, how hight from the horizon). These values change over time, so make sure you have selected the moment when you want to observe it 👇🏼
4.- launch @photopills and choose a location where you would like to go using their planner. Follow the indications of the image 👇🏼
5.- go to google maps and try to find an image from the location you chose in Photopills. Using the Photopills planner you can extrapolate where the comet will be in the horizontal axis. The altitude from Stellarium (and a bit of math) helps you get the vertical axis. 👇🏼
All left is to go, have clear skies and enjoy a well planned session!
