Just as a quick proof of concept Mavic Air Asteroid Quickshots lookalikes can be made with really little effort even with spark.
And I can set the pace, rotation speed, change the projection type at any given time and the best thing I won't have those ugly bars in the end.
Now I am still hoping DJI will bring Boomerang to other Drones, but I don't need asteroid since it is too unflexible anyhow.
Thank you!
For stitching I used Microsoft Image Compositing Editor and for editing I used Insta360 Studio and Sony Vegas.
Some minor Photoshop work to get the stitched image to a full fledged equilateral in between.
