Find Comet Lulin in Stellarium

I am starting to get quite excited about having Comet Lulin to image, so if your like me and want to know how to plan your observing or astrophotography then you’ll need to know how to find Comet Lullin in the sky.

I began using an old version of Starry Night Pro, but that would not show me the comet. So I decided to install Stellarium again on my laptop. By default Comet Lulin is also not in Steallarium, but I did find a way to map it into Stellarium.

Install Stellarium, if you have not already

Located the ssystem.ini file in the data folder where you installed Stellarium

Edit the file and place the following text at the end of the file:

name = Lulin
parent = Sun
radius = 1000
oblateness = 0.0
halo = true
color = 1.0,1.0,1.0
tex_halo = star16x16.png
tex_map = nomap.png
coord_func = comet_orbit
orbit_TimeAtPericenter = 2454842.1414
orbit_PericenterDistance = 1.212289
orbit_Eccentricity = 0.999987
orbit_ArgOfPericenter = 136.8614
orbit_AscendingNode = 338.5353
orbit_Inclination = 178.3730
lighting = false
albedo = 1
sidereal_period =

Then save the file and re-start Stellarium

Use the search facility in Stellarium to locate the Comet Lulin

Lulin is also in the Meade Autostar database as C/2007 N3 Lulin, so if you are outside already it should GoTo it, otherwise just connect your telescope to a computer and do an update within the Autostar program.
