But i think youll find you get better results doing it manually once you get the steam up. I don't use the automatic features even for very small projects like this  U776HC opamp. 6 frames using a 10x objective iirc.

Agree, these smaller planar subjects with a few simple stitches are not that difficult and don't require much from the setup and lenses involved. However, even these subjects can and will cause issues when they are positioned for depth rendering.

When one wants to print depth chip subjects the size of walls rather than a postcard on a screen for the net, and still retain resolution so one can "zoom" with their feet, this is where the skill, knowledge and effort go from Elementary to Post Doctoral levels. When you mentioned you had acquired a probe station and using Mitutoyo lenses, we knew where you were heading :-+

Best,

Never tried CPFind tho, it might not have been available when we started the massive S&S efforts many years ago.

Hugin is still no walk in the park, one needs to know how it works (not too complex but RTFM is in order) and what to click and when in order to make progress. The default settings and the "beginner mode" are hopeless - they try to match every image with each other, wasting a lot of time and usually getting confused by similar features which just aren't the same.

The upside is that everything produced automatically can be reviewed and corrected, and most of the tiresome work can be automated. There are still rough corners, like it's fairly unobvious how to coarsely pre-align the images on a grid to improve automatic alignment.

Good for the price, though :)
