-Press align...wait

-Brightness and contrast
-Gamma panel
Final Tab - lightness and save
No photoshop, just Registax - simple.
If you have any extra Registax tips please post!

Just for comparison, Matt, my routine is similar to yours except:
- I often use multipoint alignment particularly for lunar (but only a single point for spectra
) and I use "autopick" for the alignment points usually. If it picks too many points, I clear it and increase the alignment frame size. I aim for 3 - 15 points... it depends on the image.
- Instead of optimise and stack, I choose "Create reference frame". That will create a stack of say the best 50 frames (based on the best frame you selected during alignment), which you can process and sharpen in wavelets page - then press "continue" and it comes back and optimises all your frames to the new sharpened reference frame. It helps to get the absolute best frames in your stack
.
- On the stacking page, I display the stack graph. Depending on the shape of the quality curve, I'll limit the number of frames I stack. If the curve drops steeply from the LHS in an S shape, I minimise the number of frames I stack. I have stacked as few as 10 frames. If the stack graph quality curve is pretty flat and high from the left hand side I'll stack more frames (say 50 to 150). For stacking spectra, I use the frame list instead of the stacking graph, and check every frame is aligned on the same spot exactly and delete any frames that aren't.
- In the wavelets page, I use Gaussian Linear wavelets, and I have a saved wavelet set called "Dennis Wavelets" (onya Dennis!) which has wavelet1 = about 20, and wavelet 2 = about 10. I have a second wavelet set called "Light Dennis" which is about 1/2 that. I use these as a starting point. If the data is good, that'll be all you need. If the image is still soft after applying these wavelets I bump up the higher order wavelets a bit. I don't use wavelets on spectra. Really good data doesn't need much in the way of wavelets
. Experimentation is good so play around...
- After registax I often use PS just to crop any wavelet artifacts at the image's edge and add a border and title, etc, but you can crop the edge in the Finalise page of Registax.
Play around a bit and see what works.
