M42 Great Orion Nebula

It's been awhile but the weather was nice and clear, not too cold, and I decided to check out the occultation of M45 by the first quarter moon. I set up my ETX-70 and aligned on Capella and Castor with no problem but when I selected 'Great Orion Nebula' it slewed to Orion but no nebula. I think it was pointed somewhere near Orion's belt. I then tried several of Orion's bright stars and tried M42 again. No luck. Finally I aligned on Betelguese again and selected M42 from Messier objects. Bingo, right on target. I'm wondering if the named object (orion nebula) is entered wrong in the database. I was able to see Theta 1 and 2 easily but couldn't split the trapezium even with a 10 mm ep. The nebula showed up nicely though. Nair al Saif and NGC 1980 nebula were pretty too. I found the moon and M45 and a dim star near the dark limb of the moon but decided not to wait for an occultation. M45 wasn't nearly as nice with the moon nearby and I didn't want to fool with the moon after my last painfull experience!
