Thanks a lot, I have already taken and tested it, works fine with
AlaSQL, which I am using as a DB engine.

Thanks again, I will start an intensive search after completing
application. Filling DB with the content will be an endless
procedure :).

Sorry for the inconvenience, it was my fault - I forgot
to comment out debug info and all 13979 records of NGC were printed to
browser's page. Now it works fine - no more crashes, I promise :).

Glad to hear it, as I am now taking care about mobile platform(s) too.
In general, it will support desktops, mobiles and VR headsets.
But nothing to see there yet and it's only a template, which I am
turning into a real application very fast. Hope till Saturday it becomes
much more interesting :).

Thanks, very well, I will examine it later, as now I am too busy with
coding. I have also registered in this serious astronomic community:
https://www.cloudynights.com/
and hope for their support.

The most desired thing for me now is coordinates of constellation
bounds, as I would like to store them as vectors to control separately -
one by one, but not sure if such a thing exists anywhere.

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.
