Hello everybody!
It's a long time I don't write here, although I always read marvellous astro adventures from you.

Here is my (simple) question. I need a consistent, vast, huge database of existing deepsky objects.
I already used the great SAC 8.1 for my Visual Sky Assist, but I need more and more.

Due I observed objects that are not in the SAC database, I should need a complete set of DSO, a database to download.

Do you kwon anything could fit my business?

Thanks so much guys.
