Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_55 ( right_ascension___j2000__ VARCHAR, declination___j2000__ VARCHAR, ngc_number VARCHAR, constellation VARCHAR )

### Question ###
What is the right ascension (J2000) with a Declination (J2000) of 12 43 , is a constellation of dorado, and has an NGC number larger than 2068?

### Accurate SQL ###

SELECT right_ascension___j2000__ FROM table_name_55 WHERE ngc_number > 2068 AND constellation = "dorado" AND declination___j2000__ = "°12′43″"
