Re: 42 or 58 diameter tubes

Now I am curious...

A string of 58 mm tubes with screw threads should be extremely stiff. So, do your current tubes have floppy bayonet connectors, or is something else going on?

Re: Need help making a diffuser

smimo, perhaps you have already read some of orionmystery's articles about concave diffusers. If not, then I suggest to do some internet searches on "orionmystery concave diffuser", and start reading. Those articles will perhaps complement some of the excellent material in Thomas Shahan's video. (Th...

Re: Diastocera wallichi tonkinensis

Very nice!

In the full size version, it looks like the tip of the beetle's left mandible is tucked behind the leg.

Is that properly rendered, or is there some sort of "transparent foreground" artifact?

Re: 10X infinite objective help

A good fit for you might be Nikon CFI BE 10X NA 0.25 WD 6.7 (part number MRN70100). The relatively short working distance (6.7 mm) is usually no problem because the objective has a narrow conical tip that leaves plenty of room for light to get around it. The objective should cover full frame with no...

Re: Some 3D printed accessories for the Godox TT350 flash

The printer itself is a Creality CR-6SE, and is relatively affordable. At https://creality3d.shop/collections/3d-printer/products/creality3dcr-6-se-3d-printer , I'm seeing a list price of $399 for ship from US. Is that the right unit? If so, then I'm having a jaw-dropping moment about how cheap & g...

Re: Watermite

Lovely -- I like simple solutions that work really well!

Am I correct in thinking that the polarizer is to cut specular reflections from the left side of the mite?

Re: Watermite

Very nice! The illumination really is excellent. Is this conventional darkfield using a condenser, or did you do something special?
