Try this...

1. After doing and initial alignment be sure to move the slider all the way to the right. This will include ALL frames. They will be sorted but we want to include everything. The initial sort can be thought of as sorting everything to make a good reference frame... which is just what we will do now.

2. Press the LIMIT button. Create a reference frame stack of about 50 frames. Registax will take the first 50 frames which it previously sorted and assumes are the "best" for now.

3. Once the reference frame has been stacked, apply a very slight wavelet to bring out just a little detail. Don't over do it at all. Click "Apply All" and then "Continue".

4. Now you will click "Optimize" so all the frames in your list will be sorted against the newly created reference frame.

5. Once the optimization is complete GO BACK to the Align tab. Move the slider so that you include about 3/4 of the total frames. Click "Limit".

6. Create a new reference frame (same number of frames) "apply all" the SAME wavelets (don't change the values) and "continue". Click "Optimize".

7. Once it is complete... repeat by clicking the align tab again, move the slider to include about 1/2 of the total frames (the frame list you see here is the total frames NOT the limited frames you were just working with). Click LIMIT and go through creating a new reference frame again.

Once you have at least 400 to 600 frames in your limited list then it is time to think about stacking. Before you do the stack though, run one more optimization run but this time also run either your resample or drizzle. Once this is complete you can stack.

Basically what you are doing in all these previous steps is to continually take the first 50 frames which Registax says are the best and use them to sort (optimize) the next set. Every time you create a new reference frame the program fine tunes the order of 'best' frames. This routine should help give you a sharper image. Keep in mind that the total number of frames stacked can have a substantial impact on sharpness and resolution as well.

Here in Colorado we either have the Jet stream right over head or we have turbulence coming off the mountains so seeing is ALWAYS horrible. I have never seen a clear diffraction ring when trying to collimate.

Hope this helps! See if it works for you.

I tried it out and I know 293 is not a good number of frames but I decided to go with it. I'm sure I still did some stuff wrong but I like the improvement. I noticed that this processing method allowed me to use much higher wavelet values on the final stack. It also made the cloud bands, the moon, and the shadow, much clearer.

I'd love to see some other comparisons from people who are more technologically savvy than me.
