hi all,

 i tried to stitch 71 images of the milky way with APP. 135 mm  1250 iso  45s per panel. No stack.

Settings: 

0) RAW. Algorithm: superpixel

1) load: 71 lights,  some bias, flats, darks

2) calibrate: defauklt settings

3) analyse stars: 10000 analysed

4) register : pentagons, scale start 1, scale stop: 10, dynamic distorsion correction enabled, 

5) normalize: advanced mode

6) integrate: average, weights equal, LNC 2nd degree, 10 iterations, , MBB 10%, , no outlier rejection, pixel interpolation: cubic B spline

Integration duration: 35 hours

The result shows longitudinal and transversal stripes ( see photo)

. How is it possible to fix that?

 Thanks in advance for your answers,

 Serge

Hi Serge @sergecohenfree-fr,

Did you try to increase the MBB & that might help 😉

Or LNC 1 st degree?

It is a bit hard, but you need to try different settings I think to see what works best.
