Help create an accessible astro sharpening tool

Hi! I've created a smart astrophotography sharpening tool. I plan on making it a web app that anyone can use. I would like to make the app free of charge, but hosting and improving it will cost money. Currently, many astronomy programs are expensive and difficult to use. I would like to change that, at least a little bit. This tool is straightforward: you load your image, wait for the app to do its thing, and download a sharpened image. You can use it on your pc, mac, smartphone or whatever. Because it is still in development, there are some caveats:

1) You can only upload TIFF files

2) Because this is in beta stage, the files cannot be larger than 600kb.

3) The image should be in black and white

4) The image cannot have an alpha channel

5) Do not sharpen your image before uploading it. Just upload a calibrated, stretched image

With more development, I hope to make the app accept color images, large files etc. Help make astronomy accessible!
