Thanks for the tip. I'll try that on the next one.
Wide angle lenses are at their worst when doing panoramas and trying to fit an untracked landscape is quite a bit harder. In the past I did it in PTGui mucking around with the masking which took ages. Someone else posted a trick where you let PTGui plot the stitching points and then remove all those on the landscape portion. I imagine that is how the freeze ground tool works as well.
I noticed there are some Youtube tutorials on using Sequator. I think I'll watch them as there is a fair bit of depth to this program and because its so good its worth the effort. Lonelyspeck.com has an approach using luminance masks in Photoshop.
I used Microsoft ICE to do stitching on another pano and it works well and is simple to use and more reliable than PT Gui but PT Gui does have a lot of flexibility.
Also on another occasion I mistakenly included some of the sky in the ground part of the image, It was only some stars I missed between the branches of a tree.... It didn't like that  .
Overall I think Sequator is incredible, especially given the light pollution reduction functionality.

With this image I did a hide all layer on the bright foreground. I painted it in and a reasonably wide brush. It must have been just right as I only needed to have the brush near the tree and it filled in the areas so no stars between branches.
Trees as you know are difficult that way as the trailed stars can show through and are hard to remove.
I am hoping Luminar 4 will handle that. Too early to say but the AI doesn't seem that smart to me so far!
Also Topaz remask will mask a tree and its branches and not the sky. Its easier to use but again needs a learning curve.
