Nice, its a scarabaeid beetle, which includes dung beetles, but this one isnt one, looks like the subfamily Melolonthinae - cockchafers and the like

As someone who's about to walk into the world of tube-lenses and infinite-style objectives this is a god sent! The inclusion of different names for the same lenses are really great as well, wading through the swamp of names when trying to purchase things like this can be really frustrating! Some que...

really nice shots, but its however very much not a Stilbum, instead this is a Hedychrum species, a male it looks like.

Great stuff - I am kinda missing the Lomo 3,7x though, from what I recall it handles being pushed down quite far, would be interesting to see how it competes with these real glass monsters ;)

Gorgeous!

I'm curious about your stacking speeds, how long it take to complete, and what processor are you using?

Thanks!

Tremendous work as always! I'm surprised the "in-house" tube lens by Mitutoyo looks so poor, considering the quality of their lenses. Or is it just me that imagine things? The centre crop has low contrast and looks a lot less sharp than the others, but the off-centre and corner crops get progressive...

I was almost contemplating mentioning that males of Eumeninae (and Polistinae, but not Vespinae) have "pseudostingers" on their genitalia. They try to prick (excuse the pun, heh) you when being held, to make you think its about to sting. Dont know if they serve any additional purpose when it comes t...

Nice pictures, just from seeing the antenna tip I knew it belonged to the Eumeninae, and a male. Its for some reason a very common modification in the males of several genera of the Eumninae. It's normally not seen on images of live animals, as its on the inside/underside of the antenna. Not sure an...

no idea about the lenses, but the stepper motors are certainly usable for making an automated stacking rail, if they work that is.

The family Ascalaphidae, "owl flies" in the order Neuroptera, really beautiful insects, they look like someone mixed a dragonfly with a butterfly!

It's a cicindelid, aka "tiger beetle", probably Cicindela aurulenta, a common tropical species in Asia, unless if was collected somewhere else?

If you are considering buying more RAM at today's steep prices I would recommend testing the free trial versions of other stacking software before you splurge on memory. Besides, it seems like its the cores and not the RAM that is giving you grief, so wouldn't buying more RAM simply make the "time u...

Impressive! It's a male Chrysura in the dichroa-complex, lots of similar species to choose from I'm afraid
