Drizzle problem
« on: 2018 December 10 11:18:10 »
Hi all!

I'm trying to drizzle integrate HA-subs, to later integrate them with RGB-data. However, my drizzle does not work at all.

I did:
StarAlignment with the same RBG sub as reference image as for the RGB subs, and Create Drizzle data checked
ImageIntegration, and added the drizzle files.

After this, the file manager shows drizzle files with a content. A few lines from the terminal:

magnus@vista6:~/astro/objekt_lights/NGC7380_flying_horse/reg_HA_2018-12-10$ ls -l

Then I do DrizzleIntegration. However, when I choose the drizzle files there, they show up as containing 1 kb - despite the size reported above.

And the drizzle process results in a quite useless image.

Files are in a dropbox folder:
a sub
a drizzle file
the drizzle integration

What am I missing here?
