Ever wanted to use a lasso, marquee, or magic wand tool in PixInsight to help you create your masks? The wait is over!
Welcome to DynamicLasso
Welcome to DynamicLasso — a PixInsight process module for building grayscale masks by drawing regions directly on an image. Instead of relying on pixel value ranges or star detection, we trace the areas we want by hand — freehand, as a rectangle, an ellipse, a polygon, or by using the magic wand — and DynamicLasso turns those regions into a standard mask image we can apply to any view.
Each region we draw is a discrete, editable step. We can keep adding regions, subtract from what we have, soften the edges with feathering, grow or shrink the selection with contract/expand, and invert the whole result. Because every action is recorded in a history, we can undo and redo freely, and the complete selection is serialized into the process instance — so it can be saved, dragged to a process icon, and re-applied later.
Try it for free
DynamicLasso 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 9.99 US$. Your purchase also gives you a lifetime license to use your registered copy of DynamicLasso forever, plus free v1.xx upgrades. No subscription fees, no sudden forced re-registration.DynamicLasso 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 DynamicLasso 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/DynamicLasso/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 DynamicLasso 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 DynamicLasso will be under PROCESS > DeepSkyColors and PROCESS > MaskGeneration.
Using our PixInsight repository as the only official DynamicLasso 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 DynamicLasso module.
Register your copy, use it forever
You can install and use yourregistered copy of DynamicLasso on any machine you also have PixInsight installed, regardless of operating system (your registration is valid for any and all platforms) or number of installations, and you can use it for as long as you want (lifetime license). Just click on the "Buy DynamicLasso" 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.
