as I'm sure you know, "lucifer" just means "light bringer".
in a liturgical procession (Catholic or Protestant), the person carrying the candle is called the lucifer,
just like the person carrying the cross is called the crucifer.
I myself have been a lucifer.
the name "Lucifer" occurs only once in the Bible, and then only in the King James and closely related translations.
Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
I think this is a better translation:
Your pride has been sent down to Sheol.
The music from your harps announces the coming of your proud spirit.
Maggots will be the bed you lie on,
and other worms will cover your body like a blanket.
12 You were like the morning star,
but you have fallen from the sky.
In the past, all the nations on earth bowed down before you,
but now you have been cut down.

I think it's referring to the king of Babylon and comparing him to the planet Venus, which is also called the morning star or Lucifer.
Jesus calls himself the morning Star
“I, Jesus, have sent my angel to tell you these things for the churches. I am the descendant from the family of David. I am the bright morning star.”

so it's not surprising at all to me that the Vatican has a telescope named Lucifer.
when you say they use it to watch satanic alien activities, are you looking for the best in other people?
or assuming the worst?
Love never gives up.
Love cares more for others than for self.
Love doesn’t want what it doesn’t have.
Love doesn’t strut,
Doesn’t have a swelled head,
Doesn’t force itself on others,
Isn’t always “me first,”
Doesn’t fly off the handle,
Doesn’t keep score of the sins of others,
Doesn’t revel when others grovel,
Takes pleasure in the flowering of truth,
Puts up with anything,
Trusts God always,
Always looks for the best,
Never looks back,
But keeps going to the end.
