Congrats!
Maybe use bound_20 (top-left in the select-box).
Thats the epoch, bounds_18 means 1875.
They are slightly different.

Thanks for the suggestion, this man provides more details about
this subject: https://pbarbier.com/constellations/boundaries.html
Probably I need to dive deeper into astronomy and need a good book for
beginners. School lessons are not enough and were too many years ago ...

Here is large-scale prototype for what I am doing:
http://aladin.cds.unistra.fr/AladinLite/
I am plan to make something similar, but less scientific,
more user friendly, with better GUI, higher quality images
and VR support.

Shame on you. I've absolutely never made such mistakes...

Interesting site, I didn't know yet, maybe I'll sign up too.

I also found Aladdin yesterday, but I didn't want to spoil your fun :)

Thanks for that, this little piece of information can potentially save a lot of
searching.

I'm pretty sure you can't wait that long, but I also dealt with constellations,
lines and borders in December. Corresponding 3 or more database tables as well
as a Povray macro collection are in the works. However, I need time for the
completion, I have just started something else. Will probably not be finished
until March, or even later.
