Thanks, Dr. Spencer!
So maybe I have a better chance with my second-most-favorite guess at a real KBO:  Master ID IH290587That gives a pair with nice equal-looking-magnitude with ~36 pixel separation. |

...In one case I saw an even pair that was clearly separated but not easily marked by one circle. So I used two circles to mark them ...is this OK or perhaps just confusing?

Just to let everyone know that the first 2011 KBO search data are now posted on the Ice Hunters site for your searching pleasure. Currently we've posted the early June 2011 data set from Subaru (without seeding with artificial KBOs, for now), to be followed later by the early July Subaru data and the late May / early June data from the Magellan telescope.
Have at it! We'd love to have some preliminary candidate KBOs in hand when we apply for 2012 telescope time starting in mid-September. And thanks again. By the way, there's a blog post from me describing our July Subaru run on the New Horizons site (it's also posted on the Ice Hunters site, but with fewer pictures  ).John |

Icehunters now has many of the reviewed objects identified as variable stars.

Some are now marked as KBO - confirmed including a couple of mine

And here is a field showing three confirmed variable stars and a confirmed KBO (VS circled red and KBO circled green in the inset).
Also there is a forum exchange with a member of the science team.

Haha, yeah that was me trying to point out the faints need marking too. Still seems a lot of people are only marking the obvious ones.
Four of mine are confirmed KBOs so far. |

Hi,
I was wonder how many KBO's potential targets to New Horizons, and make this grafic.
I downloaded MPCORB dated to 16 Oct. 2011 (566207 bodies) and view only that who are d > 30 AU ( d - distance from Earth ) I use Guide8 software, there are no r limitations ( r - distance from Sun ) So, it's no good for NH and it's potential KBO targets

Adam,
That's to be expected. In general, KBO searches have been avoiding this area, because of the large number of background stars. You can see some of what the raw fields look like on the edges of pictures. Their algorithm subtracts two images from each other, but can leave large residuals that are difficult for a silicon computer to deal with, but fairly easy for a carbon one. So don't be surprised that the area around Pluto is empty, they've only just begun searching! -------------------- Space Enthusiast Richard Hendricks

I got one confirmed out of 3568 images, and six marked as "Likely KBO/Variable Star".

QUOTE (centsworth_II @ Jul 25 2011, 12:16 PM) In response to a request by the science team, Icehunters are really getting serious about finding faint objects! And they're going to followup on that sort of faint object, too: http://www.icehunters.org/image.php?id=59777 http://www.icehunters.org/image.php?id=59781 http://www.icehunters.org/image.php?id=59382 I have to say that with so many distracting (now confirmed) variable stars, I wasn't looking for stuff this tiny. |

With a database of variable stars, will you be able to pre-mark the known variables in future images?
