Defining regions in Target List

[PMSchu]

Hi Marcus,

Is this a clarification of your question about searching a Target List? If so, this helps a lot. You can use the Database Power Search (DBPS) to run a search of the ST4 data bases for all types of objects. Here's how I set up the DBPS to search for diffuse nebulae <5° from Sadr in the constellation Cygnus: [attachment=2821]

The search found 29 objects. Next I saved the list of objects as a new Observing List(OL) (I ran this search in ST4 Visual, but it will also work in St4 Imaging). I've appended the OL below.

The DBPS allows you to search for other types of nebulae, stars, galaxies, etc. within a specific distance of an object that you specify. The DBPS function is a very powerful feature of SkyTools. You can also search many other classes of objects.

Hope this helps,

Phil S.

Hi Marcus,

I forgot that the ST4 Visual & Imaging .stx files contain different information, so I reran the DBPS search using the ST4i program. There are still 29 objects listed in the results. The .stx file is attached below.

Interesting, the files are the same size. I thought that there was a difference between the Visual & Imaging formats. Anyway, now you have both.
