I want to view the surface of polished rocks to determine grain sizes. Would the AvenZip Scope enable me to do this?

It is perhaps his greatest strength; but small grain size is not possible; such as grain size refined sugar can be measured perfectly. sorry my english

Depends on how big the object is. The spotting scope is OK but if I had my time back I might have opted for a better one. At that range you might get about a foot in diameter viewing, never really tried anything that close. Wish I could be of more help.

No. You can't accurately test in settings. It can give you false negatives due to the metal. It is however very accurate with loose stones. Only issues I encountered were with black diamonds, and synthetic or natural emeralds, rubies and sapphires.

I do not but that is not to say you will not. I have had it out in a few different light settings enjoying the scope but not really looking for the reflection. have not looked east with the sunrise in the background or west with a sunset. Have had it outside and inside and the reflection does not seem to be there

I only use it to find stars I want to view from my telescope. This is not a scope finder for your telescope.

Thanks! Well, milling is done to your Mil-Master card / slide rule at 10x, however, strelok pro for android or iPhone will do any magnification! Any questions: RAF@RobertFosterMusic.Com ... if you want how to's or videos bro. YES, this glass is great. Leapers & USO did an amazing job on it.

This is a standard microscope. You must mount items on slides. They must be VERY THIN..... a piece of a torn leaf in a drop of water with a coverslip on top would be viewable. Anything larger, no. You would need a dissecting microscope to view something larger like a rock or plant.

I have, and it works great for viewing coins. Especially if your looking for that obscure error coin or mintmark. Very strong magnification. The only con is that the light switch wore out after about 3 months and I had to redo it.

I have no experience with one other than the built in optical finder. I suppose one of the shoe finders in the 50 to 55mm range made for full frame cameras might give an approximate field of view. I think some are sold under the Voightlander brand name, but watch out for size because some can be large for so small a camera. Sorry I can't be of much help. Don.

I am not in that field so I do not know but the scope performs well for me. Sorry I can't be of more help.

I don't know that they measure stones in grit. I can day that it is very fine, maybe 1200+

You would find this a useful tool. I work for an architect and we use it to do field measurements.

Sorry, I am not familiar with the "Cosmos" model. I am however very satisfied with my purchase. I use it to examine mineral and rock samples and it is more than adequate for my purposes.

No way. This scope is a disappointment. Clear up to 3x and that is it. Anything past that its blurry.

Yes, you cant measure the specimen size (length, radius, diammeter, rectangle, angle, circle, ellipse, etc.) in micron, nanometer, milimeter, centimeter, inch and degree and radians in angular measures.

Not trying to be glib, but actually both of the previous answers are correct. The really short answer is no, it won't, but that's really a qualified no. If you went to the trouble of acquiring, or more likely making, the appropriate probes for what you wanted to measure, then sure, this will display a waveform, but then you have to know how to interpret the waveforms, to know if what you measured is behaving correctly. In other words, you can probably make this work as an automotive scope, but by the time you're done, you'll have something cobbled together that ended up costing more and not working as well as just going out and buying an automotive scope. A purpose-built tool is ALWAYS better than a generic tool, easier to use for that purpose, and many times actually cheaper than cobbling something together.

No is the short answer. Look for "macro" lenses or "magnifier" lenses or "microscope" apps or lenses
