Hi Paul, 90 seconds is enough for the image to rotate about 3 pixels in the centre, thats enough for me.
The processing sequence in full for this image was:
- registax, load 800 frames, set mitchell 2x resample,
create reference frame, optimize, stack 400 best frames.
- wavelet settings 20,20,20,10,10,10
- gamma 0.8, brightness -10
save
Load into Astra Image, and then:
- crop, gamma scale (again), smooth with contra-Harmonic mean filter,
resample down to final size, LR deconvolution 20 turns radius 1.3,
unsharp mask Medium x 1.7
regards, Bird
