Re: Using Camera without Intermediate Optics - Nikon SMZ-U

Or you can leave the tube and add a 38 mm t-mount adapter. At least that is what I have done with mine. Although close, it is not parfocal when direct mounting to my Canon t3I. I have not really tried to make it parfocal as when taking pics I tend to tether the camera to a laptop and focus that imag...

Re: American Optical and Reichert Model 580 Stero Star Zoom scopes

The 685 shutter assembly added no additional magnification by itself. There were 3 camera backs having varying degrees of magnification that were used in combination with cameras.

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: 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...
