Good suggestion, but the areas covered by these reprojected images would span at most a few tens of pixels in Magellan images, and at locations in the images uncertain by many tens of kilometers, so it is very unlikely that we could do something like that.

A collection of surface panoramas: 180 for Venera 9 and 10, 360 for Venera 13 and 14. Reprojections are according to various suggestions on this forum. Horizon topography is probably not real, but due to inaccuracies of the reprojections (which are not strictly geometric anyway).

Thanks for your contribution. You did an interesting work.
The horizon of Venera 9 should be adjusted because the lander was sitting on a slope with a 20 tilt...

It's not easy to extrapolate much from the Venera images. I'm yet to see a good geometrical correction of all the distortions.

Those "U" shaped strips are approximations, and looking at them I always have the feeling that the spacecraft is on lower ground relating to the horizon. The imaging system is similar to that of Viking, but the scanning is made at an angle in relation to the horizon.
The Venera cameras were about 2m above the surface but, as you move from the center to the edges towards the horizon, the image looks like they were taken with a lower point of view (more like Pathfinder).
All of this makes the horizon interpretation much harder. What looks like a slope might be an horizontal feature...
