nuki 38 Posted January 16 Doing some shots of planet earth where I'd like to have plausible transformations for the sun, moon, earth (ideally including its axis wobble) and star-backdrop (rotation only) relative to each other. Since there's different models in respect to their origin and accuracy the matter is a bit confusing for me to untangle. Hence I was hoping someone here might have attempted something similar and could point me to a comprehensive resource. In the end I'd like to have a float slider to adjust datetime driving an approximation of the mentioned celestial bodies' transformations. Share this post Link to post Share on other sites

nuki 38 Posted January 16 (edited) sure - would be great if you're willing to share! in case you remember any resources you used that'd be helpful too. fyi - just found this Edited January 17 by nuki Share this post Link to post Share on other sites

nuki 38 Posted January 19 hey, thanks for your links! After some digging through what NASA has to offer I think I will either go with using their HORIZONS system (super accurate but I'd have to fetch and store a ton of data in a LUT) or the Keplerian approximation using the specified variables (continuous and I dont need to get into telnet).
