Eleonora is fairly easy to spot on this picture, but if you have difficulty, move your mouse over the picture to see it pointed out. Conditions were not good on any of these nights with light cloud around. You can see this on the picture. I used my picture for the 6th March and the very bright star in the centre of my picture (3-Cancri) and the two bright stars close to Eleonora (lower BD18 1795, upper BD+18 1793) to calculate the position of Eleonora and got RA 7h56m36.6s, Dec 18°6'3" which is in excellent agreement with the position calculated by Carte du Ceil using updated ephemerides (RA 7h57m10.23s Dec 18°6'24.78"), confirming the identification. (The resolution of my picture is about 13.5 arc-sec per pixel.) |
