Mike I started out with 5mins but I saw a lot of turbulance accross the image, the focus was moving in and out so i decided on 25. I have one section at 5ps might process it to compare.
Edit: I have attached a 5ps and 25ps section to compare. A 32s at 5fps vs 1min at 25ps and the 5ps looks sharper to me using the same wavelets.
Andrew, yours has more of a 3d effect possibly because your using a Barlow and getting close and personal. Also given your frame rater your image is sharper on details.
