Realtime image search tool in KStars : Astrophotographs browser
KStars is desktop planetarium application under KDE Education Projects. Majority of the KStars users are students and amateur astronomers who are always eager to see real time images of sky objects. To realize this demand I have developed appealing QML interface to enable users to browse through image database of community of astrophotographers which contains more than 1,00,000 (number is increasing everyday) real time and very high resolution images along with various information related to them. The images are fetched from astrobin.com using astrobin API.
Everyday astrobin.com announces one image from it's database as image of the day on the basis of criteria like votes and comments. When tool is opened, it displays image of the day of previous 20 days in a listview (Figure 1). There is search bar just above listview, where user can type search query and press search button. The images in astrobin.com database, whose title matches the search query will be fetched along with various information like Date on which image was captured, Bortle Dark-Sky Scale, RA Centre, DEC Centre, Telescope or Camera used, Description added by astrophotographer etc.
One the search is complete, user can click on particular list item to view all information related to an image (Figure 3).
Beside developing astrophotographs browser, I replaced current moon phase images with much more accurate ones. I redesigned moon phase calender to display information related to selected moon phase like lunar phase name and illuminated fraction. I also added option to choose between Northern hemisphere and Southern hemisphere since moon phase view is not the same from both hemispheres (Figure 5).
Now a days I am working on feature to display weather information in almanac tool, fetched from OpenWeatherMap using an API.
BTW, I am attaining this year's Randa meetup where I will discuss with other developers, more ideas about KStars and fix some bugs. Please make little donation : http://www.kde.org/fundraisers/randameetings2014/index.php :) to help us.
