>>3258754Here's the same tube with one of my DIY lenses. It is a longer focal length lens, at 128mm, has a single element, and no aperture. (The one in
>>3258754 was reversed and set to 18mm.) This lens is ranks in at about f/2.5 max it seems.
This shot is of the entire head of the wasp since the FL for the lens is so long. There was so much working distance that I was able to use a super long lens hood to reduce possibilities of glare from the lights. The haziness is caused by spherical aberrations from not having an aperture to stop it down.
>>3258777It will work well enough. Only the drying time really matters to you, that's really the only difference for the inside.
>>3258802Perhaps. You could certainly get shots of much smaller formations that cooled quicker when it was made. The larger stuff would be right up my ally for abstract colors and shapes at that macro level.
