Looking for a HUGE DSO database set

[davidem27]

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 (http://www.ar-dec.net/vsa), 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.

Depending on your definition of huge, will fourteen thousand objects do..?

Davide,

You can always peruse our own "Ultimate Deep Sky Observers Resource" page right here at DSF. It has a wealth of information beyond just catalogs. And its an ever changing resource. As we are forwarded new sources of information, we add to it this page to try and keep it up to date.

Hi Guys,
My definition of "huge" is more than 20k objects.

And I need a real database: XLS, CSV or something similar, like SAC.

I have to chek out the Dragan link...

In the meanwhile, if you have some more suggestion, I will really appreciate it.

Thank so much.

No one has suggested HyperLeda (PGC). The 2003 version has nearly a million galaxies and a number of astronomy software programs use this as the galaxy database. The readme file is here (http://cdsarc.u-strasbg.fr/vizier/ftp/cats/VII/237/ReadMe). The data is in fixed length fields, so you have to parse the individual fields using the number of characters. The database, itself, can be downloaded here (http://vizier.cfa.harvard.edu/viz-bin/Cat?cat=VII%2F237%2F&target=http&menu=on).

If that is too large, you can still download the obsolete 1983 version that has over 73,000 galaxies, though is not as reliable in terms of data. Here's (http://vizier.cfa.harvard.edu/viz-bin/Cat?cat=VII%2F119%2F&target=http&menu=on) the main page.

The downside of the 2003 version is that it lacks magnitudes.
