Complete NGC catalogue

[Ciswelker]

Good afternoon,
Is there a complete NGC catalogue available via Skyhound ? If there is one, where and how can i download it ?
Wouldn't it be usefull to have complete NGC-catalogue, so that you can see in 1 catalogue wich Ngc you already have observed.

thank you

Please consider carefully:

1. SkyTools uses separate databases for each type of object, e.g. open clusters, or planetary nebulae, and these database pull all of the relevant information from multiple sources into each record. If an object has an NGC number, it is stored with the object.

2. This means that the complete NGC catalog is already in SkyTools, in the sense that all of the objects should be there

3. There is no "complete ngc catalog" because that catalog is rife with errors, which include things like mis-identifications, multiple entries for the same object, ans mistakes, such as transcription errors. Even the people who made the effort to track each object down by its paper trail back to the original observations don't agree on every object. SkyTools uses the best data that I have available, but it also can have mistakes, and it has its own bias interms of which version of the catalog is included.

4. To make a list of NGC objects, you can use the Database Power Search, but I don't recommend making an Observing List with so many objects in it, as it will bog down during computations.

Please let me know if you have any more questions.

Hi Greg,

FYI your posts seem to be getting duplicated (double posted) on the forum recently.

Thanks Phil. I noticed some weirdness when I did some editing. Maybe I should have left well enough alone and not updated.
