Now I'm planning the same for 0.5. I'm also planning on moving the public repo from BitBucket to Github so the name should be decided before that. I'm just out of ideas.
What do I want from the name?
The most important thing is simplicity of writing it. Even with Bash's autocomplete with tab, difficult commands are a pain to type. The current name is quite good from this point of view but I have to drop the capitals from command names. What was I thinking when I named the executable "AstroStack"?
Secondly I'd like the name to be relevant in some way. The program stacks astronomical images, yes, current name seems to work here as well. I've been thinking names of star constellations, nebulae, galaxies and so on, but haven't found anything sufficient. Different versions are currently being named after constellations. 0.2 was Andromeda, 0.4 was Orion and 0.5 is Cassiopeia. This name is only visible at the git branch at the moment, but maybe I'll put it in a more visible place in the future.
Third thing is, I don't want the name to be boring like pyAstroStack. I've been thinking an acronym, like so many other open source software have, but I lack the imagination for this. Also the acronym should form some relevant word.
Maybe I'm too stuck with the word stacker. All my ideas seem to include that. I should try something completely different. Or maybe I'll stick with this after all. In that case I'll drop the py prefix.
