This image is 10fps 2x barlow and extention tube. But best 150 hand picked and stacked. Registax will throw some rubbish in if you let it.
Minimal processing in PP= unsharp mask, Colour contrast only. Colour contrast increased onion rings, or I should say contrast on any kind increases onion rings.
Comments welcome.
Asi I think the larger image=2x barlow and extention tube has real potential.
