Here's my attempt at the 1 July images. I did do some deconvolution this time.

Charon clears up a bit. Pluto hardly needs anything at this point.

What do you call the mouse shadow on the second moon?

Just speculating. The dark equatorial regions and the bright polar cap would seem to indicate some process leading to preferential hydrocarbon 'sand' deposition in lower latitudes as for ice deposits at higher latitudes. Except for that bright region which seems to straddle the equator which would therefore seem to show it to be some land mass analogous to Xanadu on Titan. Would this be a sign of plate tectonics on Pluto in keeping with a hypothesized internal ocean ?



Hard to tell. There really should not be anything going on its too cold but there are theories about methane snowfalls & Liquid Oxygen/Neon.. Springs/Lakes

But I know one thing...

Looking at the images we are in for some surprises in the next week

Alright have more to share here. Haven't yet done the July 1 images but I will before the night is out. I wanted to have a go at getting a hold on Nix before proceeding to have something for comparison. Each body was processed separately to maximize output...Charon.

Your Charon processing seems to confirm what I thought I saw in an earlier image. In the upper left it appears that Charon may have some higher elevations. Albedo changes? Possibly but I think when combined with earlier observations may indicate a peak instead.

Nice job on Nix. Any attempt at Hydra?

The resolution is far too low for things like peaks to be visible on Charon, especially when keeping in mid the low phase angle. On the other hand it is obvious that Charon has significant albedo variations across its surface.

Hydra is pretty dim in the series 4 June 29 images so I left it out. I may go back and try it later. July 1 has a much better view of Hydra and I will include it with that set. My process got exponentially more time consuming when I changed to this latest method followed by doing each body separately.

As for Charon, all I keep seeing is this guy from Mario:

I made an animation of a full Plutonian day using LORRI pictures from 25th June to 1st July.

Pluto, Charon, Nix and Hydra from the bin x1 images of the 1st July :

Sadly, Kerberos is just outside of the field of view...

Alright, July 1.

First image again is a composite back into the raw image alignment.

Word of caution with the small moons again. They are incredibly dim and little detail can be brought out from the raw images. One image of Nix is even just a line. Interpret as you will.

Fantastic work, Dan: it almost looks for all the world like a mini-Ganymede's ended-up in orbit around Titan.

Charon and Pluto on July 1 vs Triton from Voyager on August 19, 1989, six days out and at a similar scale. The clear filter is used. I've done nothing to Pluto and Charon except enlarged them 3x and moved Charon closer. I cleaned up the Triton image to get rid of noise and enlarged it 3x. It is amazing to see how much greater the contrast variations on Pluto (and even Charon) are.

It depends also on the contrast of camera and onboard processing. Voyager has old vidicons with 8 bits per pixel after all and no onboard processing.
EDIT: But I remember that Ganymede has pretty nice contrast on the old vidicon images so Pluto has definitely much higher contrast between different regions than Triton.

Thanks Ian!
Yeah, exactly my thoughts too. Ganymede and Titan!

Absolutely tantalizing. I am astonished at the emerging complexity of Pluto's surface, and it seems likely that Charon's is no less so. Beautiful work, Daniel!!! smile.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
