Pluto & Charon


 

Has anyone imaged Charon?

Not a full fledged dbl split. But enough of a bump or elongation, in the right place, to say you got it?


If you've ever seen the discovery photo of Charon, taken with the Naval Observatory scope S of Flagstaff, you realize how little of a bump on an otherwise round "star" it is.

I thought I'd try for it this summer. My 14" scope and camera, with it's FL and pixel size, indicated it might be? possible. Unfortunately the seeing on the handful of possible nights never gave me a chance, except for possibly one night. I haven't done the refinement of the subs to tell for certain yes or no, but hot off the press was not encouraging.

I see Stellurium will give you the position of Charon at any given time. So at least you know where it aught to be.

Years ago when I asked this question, I was told to forget about it. Not even close to maybe. But equipment and techniques have improved A LOT, And I'd bet someone has done it, or could. Maybe it's even a common check marker among master and high end journeymen imagers?

One of these days, just to add it to my "planets" collection, I'd like to get Eris. At mag 18.7 it should be no problem. Humana and MakeMake even though brighter, just don't have the same cache, for me. Sedna at 21.1 might be beyond reach.



 

Nice challenge!

I may take you up on it.

This sounds like a good target. about 0.9 arcsec maximum separation.

is there a handy link that shows separation calendar/time?
