Re: Getting better pond water samples and specimens

Hay infusions are great! If you can access some hay just put it in a jar and wait. Soon you will have a menagerie, assuming he hay was not treated in any way.

Re: Finally found a working 47.5 B&L Apo what a fine lens

No When I said "like yourself" I was referring only to having a set of the apos. I saw you were referring to a Dynoptic rather than a Dynazoom. I should have been more clear. The Dynazoom/Dynooptic scopes could have various bodies and objecive options. I have a Dynopotic with the flatfield objective...

Hmm.I will check my prisms and apply Apo's suggestion. I have several cycloptics as well. Apo is correct. The view through a B&L UWF 15 x eyepiece is excellent!

Re: Barlow 2.0x vs higher power eyepieces, implications?

I agree- Take the Barlow objective. As mentioned the objective gives twice the resolution while increasing magnification. The eyepiece only increases magnification. Most manufacturers if providing maximum na numbers generally do so with the 2x objective mounted.

Re: Finally found a working 47.5 B&L Apo what a fine lens

I have a B&L APO 61x/1.4 immersion objective. It is dated Oct 13th 1925. I have not actually tried it as of yet. I seem to recall acquiring it from Apochronaut himself! Although not absolutely sure. He may recall better. I have 2 extra Apo 47.5 x one with a frozen collar but both optics are excellen...

Re: Nikon Fluor objectives on a Leitz stand

Hey Viktor, I have not done much experimenting with objectives lately. My interests are many spread across various disciplines! Microscopy, using Compound scopes, tends to suffer in favor of stereo scopes. I favor entomology in the summers- as well as inline skating. Although COVID put a kabosh on m...

Re: B&L Stereozoom Photography ?

Re: Stacked pictures come out Cartoonish

Stacking only improves the image if the total depth of your subject can be divided into "slices" or multiple images. Each "layer" sharply focused on a given plane, then combined to make one sharper image of a much deeper depth than you can achieve with a single image. You must know what each turn of...

Re: New Stereo - Nikon SMZ800

The SMZ800 is a fine scope. I have owned two SZM800's. However, for those individuals with less spending money you can generally pick up a Nikon SMZU, comparable in terms of resolution etc. On E-bay you will find the SMZ800 commanding a higher price. So if looking for a scope with the SMZ800 quality...

You will see some image degradation when using episcopic illumination due to light reflecting internally. I have tried episcopic illumination on my SMZ-U, SZH, Motic, etc and never liked the results. I have found you will get higher resolution and contrast when the illumination is NOT presented dire...
