Hi,

When I get the sort of artifacts showing in the attached screenshot what should I do?  Drizzle?  If so, which settings would be best?

Thanks,

Andy

That looks like undersampling, but I'm not sure. Can you tell me more about what camera was used, what you did with the data etc?

If it is, you can dither (you should always do that btw) every 1-3 frames and set the amount of pixels to dither to about 10. You can read more about that here: https://www.astropixelprocessor.com/community/postid/26700/

In APP you would then use drizzling to fill in the missing data.

Thanks.  With this gear I dither 10 pixels every 3 frames.  I have 178 frames.

So my question is:  With the kind of result seen in that image what should my drizzle settings be?  Any possibilities would be helpful.

Thank you,

Andy

In tab 6 (integrate), all the way down, select the integrate mode to be "drizzle" and start with the default droplet size and scale.
