This is another drowning victim of the dog's outdoor water bowl. It was beyond the help of CPR and moth-to-moth so there was no hope for it in this world.
So...never letting a focus stacking opportunity go to waste, I brought it in and staged it using the Laowa 65mm f/2.8 1X-2X Super Marco lens as the optic for the session. The magnification was dialed in to fill the frame with the subject which was about 1.5X.
Thanks for viewing, Longshadow.

Thanks for the reply, Dennis.
Thanks, Flyguy. This one won't be flying again.
A great stack as always, sippy.

While the lens choice is interesting, I would like to know more about the number of images used and the focus adjustment of each image. This is a great image.
Great detail!!
For stinging critters, my 1st effort at resuscitation is to go with the paddles which so far has proven to be 100% unsuccessful.🫤

SB, thanks for dropping by. Here's a bit about what I do and how I do it. The choice of optics that I use is based on the size of the specimen or a particular feature that I want to showcase, like a compound eye, mandible, etc.
I mount the optic onto a means of extension and dial in the area of the specimen that fills the frame. Next, I place a metric scale where the specimen is and I read the number of millimeters visible in the viewfinder. I use an APS-C size sensor camera and I divide the number of visible millimeters into the width of the sensor in millimeters to determine the amount of magnification produced.
When I know what the amount of magnification produced is, I can then determine the depth of field in millimeters (or fractions thereof) based on the f/stop. The f/stop is kept as open as possible or a stop or two closed. Depth of field is a relationship between magnification and aperture setting. It has nothing to do with the camera itself.
Once I know that; I move the camera to focus on the closest point on the specimen that is in sharp focus. Then I advance the camera forward until the farthest point that I want is in sharp focus. This provides me with the total distance from start to finish of the images to be taken in millimeters. That distance is divided by the depth of field calculated earlier in millimeters and the result is the number of shots in the session that will be taken.
This profile view of the wasp took 118 images that were then processed in Zerene Stacker to produce the final single image.
Beautiful work. Like the color in this one also.
