Hi there

Trying to stitch a 9 panel mosaic (447 light frames). Following Sara's tutorial on this site. So far taken 14hours and only 59% registered. Is this normal or am I doing something wrong?!

Running MacBook Pro 2.3GHz i7 with 16GB Ram.

Thanks in advance

Hi Matt,

This is normal mostly because all 447 frames are checked for overlapping areas etc in the registration phase. I would advise to stack all 9 panels individually and then create the mosaic from the 9 stacked panels.

I agree with Wouter.  I had a similar experience trying to make a 4 panel mosaic by loading all the subs and hitting integrate. This is not the most efficient and quick way to do it.  Whilst I had other issues with APP’s outputs you might find Mabula’s concise guidance on mosaic workflow here helpful.

Yep, making panels first is the best and might even produce better results as the statistics become extremely complicated when doing this from all separate frames.
