- OpenBabel.Erdély, a Romanian-Hungarian Dictionary, useful for Hungarians living in Romania. It incorporates general usage words, institution names and expressions specific to public life, locality names and toponyms in general. I recommend the web gui csillagtura.ro/obe. Details on this page. OBE is also available as integrated into an editor, the obe-wordpad.
I consider maintaining this dictionary a duty towards my community.
- DSO browser - has a database of more than 200k deep sky objects, able to show their realtime apparent position on the sky from the location of the observer, and estimates imageability based on altitude, overall brightness, surface brightness, distance from the Sun and from the Moon etc. csillagtura.ro/dso uses the obe frontend, so it can be invoked from it using the :dso search argument, like NGC 7000 :dso, but the night mode /dso is the interface I recommend. I use the DSO integrated into csillagtura's wordpress to aid me with writing articles. It also has an object marking utility, which I will expose later.
- Aladin to Photo Planner - it builds on the Aladin Lite API and visualization and on DSO to help plan astrophotos.
- Polaris - for polar alignment
In amateur astronomy a short but very important task is to correctly polar align the telescope's mount. My Polaris "app" is a visual aid to do just that.
- StarHeal - in astrophotography
A program to handle dense star fields on astrophotographs, sometimes I call it starheal but doesn't really have a name.
- the putzolo
A userscript to tweek facebook's interface.
