105 mm Nikon, an OK lens

The Nikon 105mm Micro, older manual f/2.8 lens, is quite capable of giving decent 2x images on a 24mm sensor.
lens fully extended (i.e., to give 0.5x) on 130mm extension, f/8 on lens; FOV 11 mm wide; D90

For the price, and if images primarily posted on the www, it's hard to beat a reversed 28mm on bellows.

prototype for a diatom mover

Beatsy is able to make a glass needle ending in a point about 1 micron diam. http://www.photomacrography.net/forum/viewtopic.php?t=33229&highlight=needle Moths do something similar using chitin instead of glass. At the base of the leading edge of the hind wing they have a relatively long spine, the ...

LAB color mode

I purposely oversharpen (USM) my moth dissection images to show better detail. Doing so in RGB mode often changes colours giving weird effects, as sharpening affects both edges and colours. Temporarily converting an RGB image to LAB and selecting the L channel before USM results in sharpening only e...

goniometers

I guess all the above work, but if you wish to get better control over your bugs then a pair of goniometers is essential (see AnrewC comment)

The versatile 28mm f/3.5 Nikkor

This is an old manual focus model, listed on ebay for <$50.00. In my work on imaging bits of moths I have a need for magnification in the range of 5-10x on a FF Nikon DSLR 4x and 10x Nikon CFN objectives vignette badly on my setup but the image quality is so good that I can use just the center part ...

my scope ranges from 6x-50x; for insect preparation I rarely go beyond 25x. I just took a look at an 8mm (including antennae) midge; if I wanted to prepare it for photography then I would use 6x. Smaller ants would likely need 12x. Your magnification range of 5x, 10x and 20x sounds ideal for your ne...

Details are outstanding Not so sure! This fly looks like the type that has distinct grooves on the setae (those stout bristles). I can see some vague grooves on some broken setae. I am certain there are similar images on MPG that show these grooves clearly - could not find the imaqe(s). I would hav...

Fearless Fly (long post)

Can you imagine jumping onto the back of a stinging , and biting, beast about 3x your size? Well, female Thick-headed Flies (Conopidae) do it routinely. They 'attack' a bee or a wasp in flight, landing on its back and hanging on with their large clawed feet. They are predators in the slow-killing re...

Thanks Rik, This is a new species (record) for the Maritime Provinces, collected earlier this month in my garden light trap. I was processing a Zerene PMax stack when I accidently hit the wrong option in PS. I thought the effect looked better than the normal positive image. Decided to do a Zerene st...
