Planet No.10?

Regarding your other question to carry out a survey for the brightest TNOs. You'll need the very minimum use of an LX200 12 inch telescope, that will enable you to capture images at 19 mag. A C14 would be a bit better where you can achieve 19.5 mag. A 16 inch would achieve a bit better at 20 mag. If you have a high QE CCD camera you would have less time tracking.

BTW Ortiz and team (whom are professionals used a 14inch telescope to capture 2003 EL61 at 17.4 mag.

Best to use a wide FOV, therefore a telecompressor at around X5. This will enable you to achieve approximately f/5 with some of the instruments above. Ortiz used f/6

However, these EKBOs that they have discovered are exceptionally bright, most EKBOs are around 22 nd mag. which require the use of telescopes of at least 30 inches for these surveys with good tracking and high QE CCD cameras.

If you are interested and want to do a survey I may be able to help you. More details by e-mail.

Looks like this one is gonna be called Xena (zee-na).

Sounds like some astronomers are watching too much daytime TV lately!

Its a wonder they didnt call if Vulcan :lol:

Everyone knows that Vulcan is the innermost planet Dave....Tisk! Tisk! :roll:

:lol: true.
How about Andoria.
