QHY ALCCD 9

Hello there fellow nerds,

Sooo i can Buy a QHY ALCCD 9 with a filterwheel, a Set of Astronomik LRGB Filters and an h-alpha Filter for about 900 Euros.

Would this be a good Deal? Im only used to Shooting with my Canon 500d.

I get that its an older model.

It should be working with Nina, right? How about asiair?
