I will start posting some of my macro attempts. All constructive criticism is welcome.
The first attempt is a focus stack of 5 images. My guess is that I needed about 15-20 images stacked for a sharper image?

Questions:
Aperture used?
Stacking Software used?
Focus ring stack or rail stack?
The number of images required depend on a number of factors, such as: how much of the flower do you want in focus? What was your working distance? What aperture did you use?
I generally overshoot the number of stacks. In other words, I overlap more than I need to. I also stick with 2-3 stops from wide open. My "go to" aperture for stacking is f/5.6. I wouldn't stop down much more than that, unless I was going commando: Hand-held.

Thanks LoneRangeFinder for the tips. I won't close down the aperture that much in the future while focus stacking.
Another thing, it was late in the evening after work and I got lazy and didn't use a shutter release. :thumbdown:

I have also found it advantageous to start with a couple of frames a little closer than I think I have to. I've shot a quite few stacks over after realizing those little hairs I didn't notice in the foreground were not in focus. Extra frames not needed can easily be ignored. It could be my aging eyes. :-) It's not as critical with the end of the stack on the far side.I won't close down the aperture that much in the future while focus stacking.
