It is obvious that you are not happy with your Cyclops image; and I am a loss as to why it turned out so poorly.
I took this image years ago with my BHS and DPlan objective and 2.5x NFK. I have forgotten what power objective I used.
This is the quality I would expect you to get with your equipment.

The Olympus (1990) catalogue does not recommend SPlan objectives for the BHT

In some species the females give the males a rough time. The male aedeagus has to negotiate this chicane, in the ductus, that is equipped with a double set of shark's teeth; only to be greeted by spines in the bursa.

Male moths have an aedeagus (equivalent to a penis) which in many species has 'armature' Here I have dissected out the spines of a single male Cabera erythemaria moth. Each would make a fine dissecting needle if I could figure out a way to mount them on a handle. Spines are chitin (a large, structur...

I have several of this type of laundry basket with a finer weave, great for enclosing living plants + caterpillars; perhaps you could get one locally. https://www.ebay.com/itm/Laundry-Bag-Pop-Up-Mesh-Washing-Foldable-Laundry-Basket-Bag-Bin-Hamper-Storage/362971428063?_trkparms=ispr%3D1&hash=item5482...

Sorry, CFN Plan 10x NA 0.30 160/0.17

I feel somewhat of a Luddite here where many of you have switched to infinity optics. Constantly having to convince myself that I don't need to switch from my finites. So it is always nice to see a subject taken with an infinity lens that I can reasonably compare with a similar subject taken with my...

The probability of it surviving to an adult in the wild is about 1% - that's nature!

This lens reported as a very poor performer at 4x: https://www.closeuphotography.com/4x-lens-test-part-3 At 2.77x it performs well. Local back-garden ant Camponotus novaeboracensis D810, bellows, reversed lens at f/5.6, diffused flashes, Zerene PMax #1 full frame. 1st image (not used in the stack) #...

Lou kindly sent an image of his species wing at the same mag. (3.6x) as mine taken with the Laowa 2.5-5x lens
I made a plate of a small section of each, Apo-Componon on left; each from a Zerene stack, not sharpened.
I can see no significant differences in resolution.

M_C I read your blog RE: the Laowa, very informative. I was not impressed with the quality of the images shown on the Laowa web site for this lens. I don't have a Sunset Moth, or a chip. The moth wing photographed was from a common genus in Europe. I do have Vanessa cardui . Images are of the entire...

In an earlier post: https://www.photomacrography.net/forum/viewforum.php?f=25 it was suggested that the Laowa 2.5-5x might serve me well in that magnification range. Currently I use the above Apo-Componon reversed on bellows on a FF Nikon (D810) I am wondering if anyone has an opinion as to whether ...

The lens is a fixed f/2.8, reversed on a Nikon bellows
(I've tried spreading micros, impossible - need skill)

Interesting.
My text says they 'like' living with us - synanthropic (I had to look it up !).
