Hi, not sure if this is the right place to post, but here goes...

 

I am at 39N latitude.

I lost my planisphere and want to replace it, but cannot remember if I am better served by the 30-40N or by one covering 40-50N, since I seem to be right at the far edge of each one.

 

Which version is more representative of my observing position?

 

Thanks for your help...

 

Dee

Invest in a smartphone app like Sky Safari.

 

Regarding the planisphere, I would choose 30-40 degrees N. You will remember that you can't see all the stuff down to the horizon. And it will serve you better if you go south on vacation, down to Texas or Florida for example. Down to 30 degrees lets you see more of the sky.

 

If you go north on vacation, then just "cut off" a bit more of the southern horizon, and imagine a lower northern horizon. More stars will be circumpolar if you vacation in Canada.

Thanks ShaulaB. Good info.

 

I have Sky Safari on my phone, and like it for looking up a wealth of targets and info. The planisphere is my quick, hands-on, big picture tool... or maybe just a little nostalgia for my "library"... ; )
