Astronomer made it four wins in-a-row, as he comfortably justified 1/5 favouritism in the Dundalk Stadium Light Up Your Night Race.

Fourth on debut at the Curragh in May, the Aidan O'Brien trained son of Galileo has since won at Galway, Bellewstown and Listowel.

Sent straight to the front by Donnacha O'Brien, the bay colt made all. He was pushed along from two furlong pole, and kept on well from there to score by three and a half lengths. Boho (9/2) finished second, while Mister Dancer was another four and three parts of a length back in third.

"He's a lovely horse. He's a jockey's dream as he pings the gates, he lobs along until you ask him and the second you give him a squeeze he's there for you," said Donnacha O'Brien.

"He's very versatile and he's just a lovely horse to ride.

"He's not a bad horse. I don't know what his rating will be now but you could look at something like the Cesarewitch because I think he'd stay as far as you want him to and if not he could go into stakes company. He's not a bad horse at all."
