As I recently used computers without Microsoft Office while doing spectroscopy, I had some difficulties to use the ReferenceStarsFinder. I just got an ODS version to run it in LibreOffice, but i started to build a tool with Python3 and AstroPy library, from the stars database (including Miles database). It allowed me to make an easy-to-use script, able to find target's coordinates on SIMBAD and observer's place and timezone.
By example, I'm looking for stars near (10°) M27, from Vaulx-en-Velin's Planetarium (IAU/MPC Observatory L14), september 9th 23h local time :
Code: Select all
Target : m27 (19h59m36s +22d43m16s, Vulpecula), altitude=65.8°, azimuth=202° (S), airmass (secz)=1.097
Observer : lat=45d46m38s, lon=4d55m22s, alt=172m, tz=Europe/Paris, 2019-09-10 21:00:00 UTC

I made the very first interface to this script, on a web page : interface is only to run the script, results are still displayed "as it".
Performances are really poor (mainly due to modules loading, on a small web server : main processing loop on stars database is parallelized) but... it works. You can give a try, I'll try not to break it during further coding.
I'll release the source code on GitHub soon.
