Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Thank you Binastro for your kind comments. No worries. I like the Orion enough to keep it. The Minolta that you mentioned close focuses at 2 meters, which is too far for my use (observing live insect behavior). On the other hand, those microscope convertible type monoculars, such as Opticron... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
It looks like I spoke too soon. My field test showed that to observe live insect behavior, a macroscope has to focus quickly and follow the focus very well (insects move very fast). With that criterion in mind, my results are: 1) Pentax Papilio 6.5x 21 works very well (focus whel is very fast... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Gents, I got an used Orion 10-25x42 from Amazon warehouse deals for $66 shipped. Condition is like new and everything works well. For the price, I am happy with it. Binastro described it well. To my eyes, quality view is between 10 to 18x. Beyond 20x or so, image gets dark very quickly and... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Dear Binastro, You are right! Both Orion's product page and I got it wrong (Orion listed 3.3-2.4 as both real FOV and AFOV and I calculated it wrong). AFOV of 25x should be (2.4 degrees) x (25 fold magnification) = 60 degrees, which is pretty close to your 55 degrees estimation. AFOV at 10x... -

Thank you very much Gents. Binastro, your findings are very helpful to me. Especially that 25x has bigger AFOV. How do you use telescope eyepieces for close work though? I imagine they will also have very small working distances, which may disturb insects? For high quality macro (and very... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Thank you very much Gents. I was asking for apparent field of view (AFOV) and eye relief. Sorry, I was not clear. I forgot that both Orion and Pentax have their web pages for their products. So there are official specs to compare. It looks like the Pentax has AFOV of 49 degrees and eye relief... -

Thank you Jay and Binastro. I will give the Orion/Forest Optics a try. It looks like the same product is also branded as Barska in USA. Thank you Jay. Your comparism between Pentax Papilio and the Orion is helpful to me. Do you think the apparent view size (when using Papilio with only one... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Thank you Binastro. I am aware of the expensive Canon macro lens (it provides only 5x if I remember correctly) and the reverse lens+tele lens trick. I do not have tele lens though. But I will think about it more. Maybe I should buy a tele lens after all. Was just wondering if I can get better... -

Binastro, Is this the Opticron 8x20 convertible that you mentioned: http://www.opticronusa.com/Pages/gallery_scope.html I am curious if the "micro stand" contains any lens (like those you mention in your first post here). If not, that means the 8x20, when focus at 0.3 m, provides 24x by... -

Binoculars as microscope - Penta Papilio 6.5x21 vs Minox BF 10x42
Thank you Gents for your kind comments. I do not really need a 3D view. My reason for prefering bino over mono is the lack of eye strain. I do realize that monoculars can focus closer and are much easier to tether to camera. I can always record videos and view later on, I guess. I did see a... -
