Tonight I will see if I can't characterize the texturing I noted earlier. Rich has a great guy to work with thus far. And, he owns a scope of his own and understands astronomy. I'm confident of a favorable resolution.
An update for you guys on the texturing issue with my WP tube ...
When I looked at "bright" surface (a painted wall) with the gain turned up, I was able to see exactly what was going on - honeycomb. My First Light night was about 50% cloud coverage. And being a NV Rookie I had the gain way up - which was why I started to detect the issue then.
I was a bit upset about this at first. In talking with others I learned that this an inherent artifact of the way the device is constructed. Somewhat similar to being upset about light creating a diffraction pattern when it enters an aperture. No avoiding it, and useless to worry about it.
Nevertheless, I spoke with Rich at Ultimate Night Vision about the issue. He told me about the same thing, and you could go through a hundred tubes and find it in each one if you looked hard enough. Maybe one in several hundred have the feature so faint you can't see it.
Rich offered to take the device back. A+ for customer service attitude on his part.
After talking it over with him, I decided to take the tube one more time on Monday night, which was forecast to be cloud free. Also, I went to 7500' Mingus Mountain, somewhat darker than my yard. I used the eyepiece at 1x, 3x, and with an observing buddy's 8" SCT operating at f/10. Filters used were none, 650 long-pass, and Ha 12nm. (Not a whole lot of looking done filterless.)
Under the darker skies, the honeycomb was not seen. However, when I shifted my eye to attempt to focus on the interior of the NV tube (as opposed to relaxing to distance-focus to see the sky) I could find some hint of "texturing". I think what I was beginning to perceive was the "intersections" of the honeycombs, an appearance of dots. But to emphasize, with gain at normal settings I really had to search for it.
In some respects, this is typical of the obsessive-compulsive nature most of us seem to have - buy fine equipment and keep pushing it hard to see the inherent aberrations or flaws. But in the course of normal observing ... not really an issue.
So, bottom line is the NV eyepiece is showing me things better than I have ever seen in 35 years of amateur astronomy. By a very large margin. I'm keeping it!
