I've found the humble pringles tube to be as good as anything, even comes with its own diffuser and the snacks to keep you going

Salted!
I think flash is just not the thing for me. The time it takes to recharge is too long between shots to expect most subjects to remain motionless. At 10 frames per second without flash I've a much better chance of some stackable images.
Adding flash might allow a touch more DOF but nowhere near enough to warrant the expense of the frame rate.

I haven't used it for macro but for some fast karate sequences I was using 4 flashes in two groups firing alternately, it halved recycle times but is still wasn't quick enough, a little hack that worked for short bursts was to set the flash on full, let it charge then drop to say 1/32, you won't get 32 shots out of it but you should get at least half a dozen shots at low sequential speed.
Give it plenty of time to cool between bursts!
Continuous lights have a problem of their own in the pulse frequency, if you want consistent exposures you have to drop the shutter speed too low. Low energy lights indoors I'll be at around 1/20th. I have some video lights that are OK to around 1/80th but I will get a slight variation

1/32 what sorry?
Flash power?

Sorry, yes I was thinking manual, I don't think ttl would work for a burst
If the flash is charged for a full power burst, you should get a few shots on lower power before it has to recharge

Always manual with macro

That could be a little game-changer
Just had a play and at 1/32 I can get 7 shots at either burst rate
Better still is 1/16 - 5 shots quite a light difference too!
At 1/8 I can only get 3.
Thanks for that tip - that wouldn't have occurred to me at all

Let it cool, i had two taped together in a metal beauty dish with no airflow, they didn't like it

Regarding light loss with extension tubes I found this.
"On the other hand, light loss caused by extension tubes is inversely proportional to the focal length of the original lens. For example, a 25mm tube results in a 1 stop loss on a 50mm lens, but only a half stop loss on a 100mm lens, or a quarter stop loss on a 200mm lens."
From here http://www.bobatkins.com/photography/eosfaq/closeup2.htm
So maybe less of an issue at 180 with a 25mm tube.

Interesting article
I'd say the difference in magnification probably follows the same pattern. I didn't notice any mention of sharpness or diffraction in that Q&A,how times have changed
I'm still not sure how much difference 25mm tube will make, the impact on my tele lenses is marginal
I avoid this site but the first few comments seem relevant

Good find - he actually has exactly the same lens and body choices as me!
Officially the gain in magnification is about 20% with a 25mm tube
Interestingly it looks like my failed TC experiment may be back on again though, apparently AF is available at f8 and below, I think I left it at 9 or 10 yesterday when trying it.

I had to check the name
I actually read this whole thread yesterday, it's a shame so many pics are missing but there are some amazing macro shots going back a bit

Used to be quite a popular thread.
Carp angling seems to attract less "countrymen" and more "screenies" these days.
The gadget threads seem to get plenty of traffic!

Just had a quick took, over 80 "what lens" or "what camera" type threads since 2017, over a thousand posts, this thread has had a hundred posts in that time and most of them are us two over the last week
It's funny seeing some of my questions from a few years back, i remember some of the things I was trying to shoot and struggles I had with some technical details that seem so simple and trivial now. There really is no substitute for experience!
The house I'm working in this week, the garden is almost deafening with the amount of bugs buzzing about, I might warn the neighbours there'll be a nutter doing yoga with a camera tomorrow

You get days where loads just seems to fall into place then months of learning bugger all!
Found a dead one to practice on this morning so I think this is the limit of the gear I have.
180 lens, 1.4 converter, 100 ISO, f9 (which I keep coming back to as the sweet spot)
Lit by flash on full and a high CRI torch.
Focus incrementally stepped and shutter fired via EOS Utility on the laptop.
Of course I'd never get anywhere near that kind of thing in the field but interesting to see.
Length of body & head = about 5mm
