Welcome to SpotHealing
SpotHealing is a PixInsight process module for removing unwanted spots and artifacts by painting over them. Wherever we drag the brush, instead of painting a color, SpotHealing reconstructs the area underneath: it estimates the local background from the surrounding pixels and fills the painted region so the blemish disappears and the result blends seamlessly into its surroundings.This makes it ideal for the everyday nuisances of astrophotography — satellite and aircraft trails, dust motes, hot pixels, residual stars, plate defects, and other localized intrusions — without the manual matching of a clone stamp. The fill follows the local gradient, matches the surrounding noise, and can even repopulate stars if we want to, so a patch over a busy starfield doesn't read as an obvious hole.
SpotHealing is a dynamic tool: we paint directly on the image and see each correction immediately. Every stroke is a discrete, undoable step, and the complete sequence is serialized into the process instance — so it can be saved, dragged to a process icon, and re-applied later.
Try it for free
SpotHealing is not free, but you can try a 100% functional copy for 30 days. If you want to use it after that, it's a one-time payment of just 3.99 US$. Your purchase also gives you a lifetime license to use your registered copy of SpotHealing forever, plus free v1.xx upgrades. No subscription fees, no sudden forced re-registration.
SpotHealing is only distributed via a PixInsight repository (easiest and safest way to install new PixInsight modules). All we need to do to install our trial copy is add the SpotHealing repository to our PixInsight installation, which we can do in less than two minutes:
We open PixInsight, and select the RESOURCES menu.
In the RESOURCES menu, we select Updates, then Manage Repositories.
In the Manage Update Repositories window, we click Add.
In the URL box, we enter exactly:
https://repo.deepskycolors.com/SpotHealing/We click Ok to save it, and the URL should be listed along other repository URLs. We click Ok to close the Manage Update Repositories window.
With that done, we now do RESOURCES > Updates > Check for Updates. The SpotHealing module will appear as a candidate for installation, and automatically selected. We click Apply.
After that, PixInsight will inform us that the install will happen once we restart PixInsight. We do that, and SpotHealing will be under PROCESS > DeepSkyColors and PROCESS > Painting.
Using our PixInsight repository as the only official SpotHealing source also comes with the guarantee of our Developer and Repository certificates, required and verified by the PixInsight application from the moment it connects to our repository until it completes installation of the SpotHealing module.
Register your copy, use it forever
You can install and use your registered copy of SpotHealing on any machine you also have PixInsight installed, regardless of operating system (your registration is valid for any and all offered platforms) or number of installations, and you can use it for as long as you want (lifetime license). Just click on the "Buy SpotHealing" button. You'll be redirected to PayPal.
NOTE: After you make your purchase, you will receive an email from PayPal. You may or may not receive an email from us following your order, but if your account was charged, your order was placed and we'll be sending you the registration key within 3 to 5 days.
