Translate: Hans Jørgensen Østby, Askim, 1761

Could I get help translating a birth record taken from the Askim church records in 1761? My records show his full name as Hans Jørgensen Østby, born in Skjørtenberget, Askim, Østfold, Norway. I have his father's name as Jørgen Andersen Tømmeraas and mother as Dorthe Hansdatter. Does this match his birth record? I also need his birth date. Please translate all the text and names. The record is on the left side, 3rd person down. http://www.arkivverket.no/URN:NBN:no-a1450-kb20061019020347.jpg
