I wrote an online FITS viewer:
https://astro.mellican.com/fitsviewer/. My use case was to grab a single raw sub and convert the FITS file to a high quality JPEG on my big screen (as opposed to a device) for review. Sure I could use a local PC/Mac app like ASIStudio, but I wanted to do this remotely (ie. cloud based). I found other online viewers did not stretch the image, they converted the FITS to a black JPEG.
This tool can perform some basic processing to make it presentable. It is not meant to do any stacking or calibration. However, the idea of post-processing as a service is demonstrated in the attached screenshot of a processed FITS sub.
On average the results are processing in under a minute. The majority of the time is spent at the mercy of the external processing service.
The upload file size limit is currently 50MB and only FITS file types are allowed (XISFs are just too big). Subs will be purged periodically. If you want to keep it on the server a little longer, say for posterity or sharing, let me know (DM me).
Hope you find it useful. For fun, I've created a
#singleastrosubchallenge hashtag on Insta to showcase the results. Post yours there too.
