Reply With QuoteI have ecliptic longitudes (and latitudes!) for all the planets incl. Sedna, Eris, Pluto and the top dozen or so asteroids incl. Ceres.
I was able to set Starry Night to view from "sun center" and set the date to 15605-09-15-1200.
The info is overkill ... Here's Earth ...I think all I really need is this part ...Code:Looking: south west (223 degrees from North) : 44 degrees from horizon Field of View: 100 degrees (width) : 92 degrees (height) Limiting Magnitude: 0.4 Observing Conditions: Clear Sky Clock Online...

The surface of Earth is constantly being remade by atmospheric and tectonic processes, so unlike the Moon and other solar system bodies, the Earth is not marked by craters. Over seventy percent of Earth‘s surface is covered by water. The atmosphere of Earth is 77% nitrogen and 21% oxygen. Until the Apollo program in the late 1960‘s, we had never seen a view of Earth from the outside. The Apollo pictures reveal what a fragile and wonderful world we live on, a spark of life in the barren emptiness of space. Heliocentric X: 0.98568 au Y: 0.20949 au Z: -14 kmOf course Earth's ecliptic latitude is 0. Earth orbit defines the ecliptic.Code:Ecliptic longitude: 11° 59.917' Ecliptic latitude: -0° 0.000'
But, this being a flat map, I dunno if I will even include altitude above or below the ecliptic plane. Maybe as extra info. Maybe not.
... but it costs me some of the "celestial spheres" flavor ... oh well ... trade-offs ... I hope the celestial sphere flavor will be more in the graphic style rather than orbits centered on the page. Offsetting and cropping will allow me to cram more content into the space I have, because I won't be wasting space on empty stretches of orbit.
