Re: Fungus Identification Help

HI billbillt, I do not have experience with different microscopes. Comparing images from a research scope like an Olympus BX53, the photographic images from an Olympus BX53 have a better resolution -- clearer distinct borders. Though, price wise the Olympus would have to have 10 times clearer pictur...

Re: Fungus Identification Help

Thank you apochronaut, for your detailed comments! They are appreciated. Cauliflower and Broccoli were seeded on September 1 2018. It braved the winter in an unheated greenhouse in Southcentral BC Canada (Kootenay Area). Temperatures did drop to -7.8° C over winter. The cool winter temperatures did ...

Fungus Identification Help

How close can a fungus be identified from these pictures? It was found growing on the base of a cauliflower stem in Southern British Columbia (Kootenay Area) in a greenhouse. Temperature low high in the greenhouse for the last week was 5.8° to 31.3° C. More pictures here: https://photos.app.goo.gl/X...

What alternatives are there to match the eye piece field of view with a camera's field of view.

Looking for ways to match up what I am seeing through the eyepiece with what is being displayed through the camera.

Re: Picture magnification question?

Thank you all good answers. I was puzzling about a 1000x annotation on an image. The annotation does not mean much without a scale. Annotating the magnification of the objective used when capturing the image along with a scale may be better. When calibrating a camera, are x and y dimensions the same...

I have a camera mounted on a 0.5X reduction lens and am using a PH20 objective what is the magnification? I am thinking the pictures are taken at 10 times magnification.

Fine Focal Adjustment Device.

Is there an aftermarket device (or home engineered one) that extends the radius of the fine focus knob for very fine increments of the focal plane?
Should be good to use for image stacking software.
The knob on my microscope has a small radius and its difficult to focus on higher magnifications.
