looking for horse head nebula

[surket]

Hi everybody,

I would be grateful if you could tell me how I can find my favorite DSO, the horse head nebula, in Celestia.

Many thanks,

Ben

Ben,

Celestia's installation kit does not include any gaseous nebulae. In order to view IC434, the Horsehead Nebula, in Celestia, you'll have to install or create an Addon. A 2D "billboard" addon is available on the Celestia Motherlode on the Web page http://www.celestiamotherlode.net/catal ... ebulae.php

P.S. Another 2D version is available at http://www.lepp.cornell.edu/~seb/celest ... d.html#5.4

Thanks, I can appreciate the problem now.
Is there a way of setting the magnification / FOV (or indeed other parameters) exactly? I use mouse to change FOV which is very rough and ready.

One way to do it is to write a one-line CEL command file:

Code: Select all

{
set { name "FOV" value 35 }
}


where the number after the keyword value is the field of view.
(Well, OK, I wrote it as three lines, including the required beginning- and end-of-file braces. )

Cel commands are documented in the Wikibook at http://en.wikibooks.org/wiki/Celestia/C ... mand_index
