Much better than Image:Viewfromtitan.jpg, since that one has the orbit incorrectly tilted out of the ring plane. If you do a version 3, you might increase the curvature and decrease the distance to the horizon (Titan is about the size of Luna).--Curtis Clark 06:25, 26 July 2006 (UTC)
- Yes, that is a bit better. A few comments though:
- Saturn still appears a bit too distinct. In visible light, Saturn would appear very fuzzy, if visible at all during the day. The sun would also appear very indistinct, really nothing more than a bright patch in the sky, it would not appear as a bright point. In terms of surface science, the dunes we have found are more longitudinal in nature, see the Titan article of the dunes for inspiration. They would not appear like the dunes seen here. The hill seem to be an appropriate height. --Volcanopele 16:41, 26 July 2006 (UTC)
- Also, I notice now that the shadows are all wrong. The position of the ring shadow, and the illumination of Saturn, is consistent with the sun being over my right shoulder, rather than where it appears.
- Check out Celestia], a space simulator that will help you get all this stuff right. It's hard to position onto a planetary surface, and the Titan cloud deck is so thick in the simulation that you'll have to turn it off to see anything, but with that accounted for, you can set up some really good views as models for your work.--Curtis Clark 22:39, 26 July 2006 (UTC)
- This is much better then before, though I think you can keep Saturn up for artistic licence. You just might change the caption to reflect that Titan doesn't truly resemble this very much.--Planetary 03:46, 29 July 2006 (UTC)
Criticism
[edit]Based on the position of the sun and Saturn in this painting, Saturn should be a thin crescent (like the moon near the new moon phase) rather than full or nearly full.—The preceding unsigned comment was added by 66.47.51.78 (talk • contribs).
Beautiful evocative image; I admire the work. However it seems the main article suggests that the atmosphere is rather more opaque than depicted (the Huygens probe could not even detect the sun's position, and photographing the surface was like asphalt at dusk, etc). Also my calculation tells me that Saturn would subtend an angle of about 2.83 degrees from Titan. This is a sizable disk (about the size of a fist at arm's length) but not as large a fraction of the sky as Saturn appears to use in the image. Perhaps our astronaut is using night-vision binoculars, eh? I hope to see your vision of other planetary bodies throughout Wikipedia.
