A wall map of the galaxy / local group to put pins in for observed astronomical objects.

 

In one of the scenes in Contact, the younger Elle puts a pin with strings in a world map to track all the places she’d spoken to via Ham Radio. I’m wondering if astronomers have anything similar.

 

I’m a spatial / visual person. I like to know how objects are located relative to one another, For example, while M42 and M31 appear pretty honking big in our night sky, one is in our approximate neighborhood in the galaxy and another is much further away, though still belonging to the local group. Just observing them, you get no sense of that.

 

I wonder if anyone has ever developed / printed a set of projections that would allow us to plot our observations on a map/chart. 
 

Something like these, but spiffier.

I'd like to find a detailed map of the Milky Way as viewed from above the NGP.   Google search has yielded a mix like OP's attachments - ok but not as detailed as what I'm looking for.  Maybe the thing to do is take all the maps you can find and combine the info into a DIY.

 

The latest issue of Sky at Night magazine has instructions for making a model of the solar neighborhood with colored beads for stars glued on skewers for distance above and below the ecliptic plane.  That might be a good project for a snowy January night.

You could take the GAIA EDR3 data and map all 500Gb of it as a 3d model, but I imagine there'd be a lot of holes for the parts we can't see.

Thanks for letting me know about that Sky at Night piece, jcj. Would that make for a 3D model even? I’ll check it out!

It’s an amazing project. I wonder if anyone has ever annotated a map like this with Messiers, NGCs etc…

Yes, it's 3-D.  They use a cardboard disk and glue skewers to it to have stars above and below the plane.

 

I'm thinking about doing one with a wooden base that could sit on my desk.  Have to add an offset to position all the stars above the base or leave a few out though.
