It's 349073, the one after your left-hand image here.

Here is my set of Voyager images of Tethys:



Specially processed to enhance both topography and albedo.

I tried producing a color image of Helene, but to tell the truth -- the thing is as white as can be.
The left image is approximately true color using R/G/B filter combo, the middle is stretched color using IR1/GRN/UV3 filters and the third is the RGB image heavily color saturated to bring out very subtle color differences. The same result turns up if using the stretched color so I omitted it.

As can be seen, the surface seen in visible wavelengths is very uniform and bland.

Again on Helene imagery...
I processed the 6 frames from green/CL filters, using Registax for stacking and for detail enhancement (I'm just a beginner with this powerful software, but results are very encouraging ).
Then I used UV/IR in order to have also a color version, but I had to enhance saturation (as ugordan):



I made also a low luminosity enhancement of the B/W stacked image, in order to show faint details as already done by Phil (colors are due to different gamma curves assigned to the 3 components, not real!):


Note: images are enlarged by 50% from original, so scale should be 270m/pixel.

If they release a b/w version that isn't autostretched on the photojournal, it would be neat to overlay your color version on top of it.

Here's a Rev 21 Tethys grab bag:

Very nice!

In fact, autostretch make impossible to establish the real hue of the satellite... we can only say somenthing about color differences in various regions.
Anyway, I repeated previous work on the RGB pictures and results are showed below; now colors appear different!

I suspect that feature in the top could be a huge crater rim, with central peak emerging from the darkness...
