Beautiful image of Dione
 If Dione didn't have those white streaks it would look a lot like Iapetus |

That reminds me of a Voyager picture.

Good stitch Doug. I still don't know how to align the images as well as you did, but I deinterlaced the right part of this image:

Very nice work, Doug. The resolution on those images is 430 m/pixel.
BTW, doug, which filter did you use? If you used the IR1 filter, then the lower right frame was summed. All the others were not. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

The IR1 filter. It's not a perfect stitch - just rushed it together to have a look at the full picture
 I've deinterlaced all four images, and resized up the bottom right frame (didnt figure that that's what it needed ! works a treat though ) and thought I'd try using the same pan program I use for my MER pics - PTGui.It works a TREAT!! I just set the f.o.v. of the lens to be 1 degree (I'm not sure what it actually is - but I figured that 1 degree is nominally very very small, and small enough to not inflict and sort of distortion on the image as one would at 16.6 or 45 like with MER ) At first try - it classified the control-point accuracy as 'too good to be true' at less than half a pixel I've never EVER had that with ANY other pan I've worked on, be it MER, MPF, or normal digi cam stuff from this planet http://mer.rlproject.com/dione_dec15th2.jpg Now THAT - is a perfect stitch  Doug |

 WOW, even better. Would you mind if I sent that to a couple of team members?

Are there still more images of Doine waiting to be transmitted (or at least released on the Raw Images page?) It would seem based on the use of interlaced compression that these are the first of many.

Wow.
Is that straight line near the terminator real or an artifact? |

I was also wondering about the slight diagonal lines near the center of the image. Looks like it's scraped with a brush. I'd be freaked out if that wasn't an artifact of some sort...

I thinks it from the lines in the raw image.
