Using Reference Frame While Stacking In Registax

[gbeal]

Hi,
one snippet I gleaned from Mr Ponders during the course of the Taupo weekend was that he uses a reference frame while stacking in Registax. He took the time to explain this to my processing slave, and we tried it tonight.
The original avi was shot last night, and with mediochre seeing. The first (left hand) image is how we would "normally" stack. Using Paul's method (with a reference frame) gave the right hand result.
OK, so it's subtle, and very at that, but there is a slight difference, and these days it is that slight that makes the result.
Try it, and hopefully Paul will elaborate should you have any curly (for me) questions.

Gary, I also use the "create reference frame" option in registax, I think it's one of the most significant improvements in the program over V2.

Just make sure that you don't apply too much wavelets when "enhancing" the reference frame or the fine alignment won't work as well as it could.

Hi Bird,
thank you, it is always good to garner a pearl from the master.
It looks like we will be using this method now.
Regards,

I've used the "create reference frame" too, since R3 came out. Like you said, the difference sometimes can be subtle but I can understand why it's there and why it would work well..

As bird said, slight adjustment in the wavelets screen, then go back to align, and it's looking for frames that look more like the final result you want. It should rank the truly best so you can eliminate the bad ones with the stackgraph slider.

I infrequently use the reference frame creation. I tend instead to se the gradient selection and push minimum to 95%. When I have used the create reference frame it sometimes gives good results and sometime not. It all depends on the Avi to begin with. Still it was a creative addition to the Registax3 version.
