Hi Ray,
We don't have more video tutorials for now.
I hope that our new implementations under the new PixInsight Standard beta application will be, besides much more powerful and sophisticated, more user friendly. They will be available for wavelets and the rest of LE functionality in a few weeks.
Along with that, we are making continued efforts to improve our documentation. We are now focused on the documentation for the PCL development framework, but a comparable work will be done for the new application and all of its standard modules.
If you have any specific questions about wavelets or other processes in PixInsight LE, please don't hesitate to post them to this forum.
Thank you
