I fixed the Bortle Scale by building my own light pollution map from scratch using a light pollution scattering kernel using the CU Boulder VIIRS dataset.
Previously, the dataset I used didn’t have enough labels for each bortle scale and had country borders, which screwed with what the expected light pollution is.
I’ve taken your feedback from the last ship and I’ve started work on a more space-y theme for this project. So far, I’ve switched up the color scheme to a dark blueish-purple and comsic latte (The average color of the universe). I also added a procderual starfield with comets in the background. Also, check out the homepage, the page cards also float around like they’re in microgravity!
I did a lot of space saving (pun intended) to reduce the offline cache size by about 0.7 Mb to 3.8 Mb by better compressing images and minifying code and JSON. I also had to do an emergency fix for mobile, where it wasn’t working on certain phones.
Added a guide to Astrophotography tools to make it more beginner friendly.
Added milky way to star chart! It looks kinda cool how it wraps off the page and it definitely wasn’t because it was too hard to remove it.
I added a FOV preview, which shows how the 110 messier objects appear in photos based on your camera sensor size and lens focal length. It’s very useful for deep space imaging.
As a prize for your great work, look out for a bonus prize in the mail :)
I added final UI improvements ahead of shipping and reduced redundant code
Added a stacking calculator to show how well a stack of images will look based on their signal to noise ratio
Did some compression work to bring the download size down from 16 MB to only 4 MB. Mostly compressing images, but also making a new catalog, reduced catalog for stars.
So, it turns out I didn’t need to enter all those lines manually, there are saved files out there for it.
I got more constellations (Hydra, Bootes) and added offical International Astronomy Union names when applicable
Ha, I added orion and aries. This took forever b/c orion has so many connections
I’m working on an offline star chart generator. I’ve been working with Astronomy Engine and the Yale Bright Stars Catalog to find the proper motion of the stars. I’ve only added the Big Dipper, but I plan add more of the 88 IAU constellations.
I actually used my project. Here is a shot I took of Bishop Pass in the Eastern Sierra Nevada mountains.
Worked on getting the project deployed to Vercel (A lot of headaches with relative and absolute paths)
Add redlight mode to prevent eyes from getting burned while adjusting to the dark
I spent way too much time debugging how to use the data from lightpollution.it to find the light pollution index at a coordinate. Turns out they were using an off-centered projection that I used ChatGPT to decode (x = (lon + 126.44) / 0.03382; y = (-20.28 * lat) + 1862.4;)
Created the equivalent exposures tool to calculate values for each part of the exposure triangle based on other values.
