S. 'Mars'

What not one for Earth?
Lynn do you have these?

Hi Spring. I have Mars, Uranus and Saturn.

Nice.

Sorry, LYnn, have to be devil's advocate here. Pluto is no longer a planet. Also, what do we do with names of other objects in the solar system? Then there are the ones named after stars, such as S. Sirius? Love the idea though. Have to find a solution for this.

series: Space!

It is still considered to be a planet, a dwarf planet.

Should we call it the Planets and Heavenly Bodies Series?

Good Idea! I like that Heavenly Bodies.

I love the Yellow Comet and Havendijks Milky Way.
I will add these to the above list.
Whoa is me, these are only in the European market.

So, that just means you slow down a little bit.

I think I only have Neptune, but I have a LOT of Neptune now.

Tabby, do you have a photo of Neptune?

Not a recent one, but I've put two in the database back last year and in the spring.

I just went and looked, what a beauty that one is.

Took some new pictures yesterday that include Neptune. I'll post one when I get around to downloading them off the camera.

I have a bunch of photos to take care of when I get back home.
