Amazing pictures, Thank you! The stars reflecting off the water was amazing.
Tube type and specs? |

Nice pics and nice work, enjoyed all of your outdoor magnificent shots!

Thanks guys! Yea, sometimes the simplest setup works the best. I spent about 45 minutes in the hardware store gathering all kinds of parts in an attempt to make some sort of elaborate camera mount, then when I'm on my way up to the front of the store I see this rubber pipe fitting with clamps and everything for $4. Problem solved!

Awesome pics, and I do believe I've been inspired! Going shopping for a rubber dodad like you made up very soon.

Let me know how it goes and make sure to post your pictures once you get it set up! If you have any questions about camera settings I'd be happy to help out. It's really quite easy once you tweak the settings a little bit. |

What kind of exposure times are you using? I ask because that lens you're using is pretty slow, so you'd need to crank up ISO or exposure times (or both). I assume you're at or above one second? Probably keeping the ISO under 800 to keep noise down? f4 or f5.6 on the aperture to keep it sharp?
ETA: Not dissing you, BTW. I've been able to get excellent TTL NOD images when on a tripod with longer exposure times. That also "cleans" up any tube noise, since the shutter speed is too slow to capture fixed noise patterns. |

View Quote Exposure time is the setting I change the most. If I'm using a tripod, I keep the ISO at 100 and play with the shutter speed until the picture looks good. Under darker conditions, I usually start somewhere around 1 second and move up or down from there. I mostly keep the aperture on the lowest f-stop (f3.5) in order to gather as much light as possible. I suppose I could try a narrower aperture to bring more objects into focus, but I'm not sure how much it will help since the PVS-14 has such a shallow depth of field anyway. When I'm shooting by hand I increase the ISO to anywhere from 200-800 and increase the shutter speed accordingly. It involves a fair bit of trial and error and I usually take a bunch of pictures under a range of settings and pick the best ones. |

Try the bracketing mode, saves you some time up front fiddling with shutter speeds.

By stopping down 1-2 stops from maximum it will sharpen the image up considerably. It may not have that much effect on an NV image, since the tubes are low resolution anyway, but typically the maximum aperture on most lenses is also the softest when it comes to resolution / sharpness. Of course, you'll have to dial down shutter speed or dial up ISO to compensate. With an f/3.5 lens it would be sharpest at f/8, but even 5.6 would be a dramatic improvement -- for "normal" photography anyway. It may not make that much of difference through a NOD. Try shooting some video and post that. |

I'll try narrowing the aperture a bit and see how that goes. Sounds like it should be an improvement, especially for brighter conditions. The fact that I can even partially understand what you guys are talking about is kind of amazing to me. Before I started taking night-vision pictures a couple months ago, I didn't even know how to work the basic functions on my camera. Now I'm on here talking about ISO's and apertures like I know a thing or two Do you think it would help to get a faster lens like this? http://www.amazon.com/Nikon-35mm-1-8G-Digital-Cameras/dp/B001S2PPT0/ref=sr_1_1?ie=UTF8&qid=1409231831&sr=8-1&keywords=nikon+f1.8+dx+af-s |

That is extremely impressive. My pictures always look like bigfoot/ufo pictures when I try to use a real camera like the 7D or 5D. The only thing I can ever get pictures through is an iPhone, and they look like...well, phone pictures.

Now for that 35/1.8 get it for personal non night vision use, it is a killer lens |

Like PBJ, you could stop-down two full stops and still be at f/4. However, on an APS dSLR the FoV crop would probably cut off some of the image circle. At what MM does your zoom begin to crop the circle? If you can set it at 35mm and still see the entire circle, then I'd say go for the prime you listed above. Also, it will open up options to you for normal photography. It's two stops faster than your zoom at maximum aperture, which is great for indoor / available-light work without having to dive too deep into the ISO pool. That, and it's cheap for what you get. |

Okay, you guys convinced me to go ahead and get the faster lens. I picked one up at Best Buy this morning. The zoom at 35mm does cut off some of the image circle. It pretty much has to be at 18mm to get the entire thing. No big deal. I can just crop it or leave it as is depending on what I'm trying to do. I'm sure it will come in handy for other stuff like video and non-night vision photography. I also made a better camera adapter that attaches to the existing threads on both the camera and PVS-14. This piece should make switching out camera lenses and NVD's a lot easier and it only cost me $6 in parts and about 10 minutes to make. https://farm6.staticflickr.com/5595/14879092387_59434b47b2_z.jpg Parts: - (1) 52mm UV filter ($5) - (2) Washers ($1) - (1) PVS-14 Eyepiece retaining ring (already had) - Super glue (already had) https://farm4.staticflickr.com/3921/15042637586_52ebba8e5c_z.jpg https://farm6.staticflickr.com/5591/14879060158_a73a7570df_z.jpg https://farm6.staticflickr.com/5591/14878994930_3de987ccf3_z.jpg To make the adapter: 1. I broke the glass lens and removed it from the UV filter (turns out I could have just unscrewed the retaining ring). 2. Unscrewed the retaining ring, inserted the washers and glued them in place 3. Screwed in the UV filter lens retaining ring on top of the washers and tightened it down 4. Inserted the PVS-14 eyepiece retaining ring in the middle of the washers and secured it with some glue The glue isn't necessary, especially if you get the right size washers, because everything will be sandwiched together once it is attached. I went ahead and glued everything in place to make sure it didn't shift once I got everything centered. https://farm4.staticflickr.com/3906/15065924305_1e052c04aa_z.jpg[/url] https://farm6.staticflickr.com/5578/14879217447_46fd2dec9c_z.jpg View Quote View All Quotes View All Quotes Quoted:

Really beautiful pictures, thank you - they are truly awesome - It's been a while since someone posted some trip photo's up on the board :)
And great photography too - Did you remove the eyecup holder before fitting? David.

Forgive me if this is a dumb question, I am new in the PVS-14 game and I really want to build one of these for my video camera with a 30mm filter size.
Does the Eyepiece retaining ring have threads that screw into the eyepiece? The only tech manual that I have found mentions epoxying the ring onto the eyepiece. If it is threaded and not epoxied, will removing it open the system and lose the nitrogen purge? Love the pics and thanks for the great idea. Gringop |

All of my single battery PVS-14's have removable eyecup retaining rings with threads. On the one dual-battery housing I have the ring is permanently attached, but not sure if that's true for all dual battery housings. No, the threaded ring simply screws off and you will not lose your nitrogen purge. |

Rich,
Exceptional images, just as you have produced in the past. The creativeness of the adapter is also very impressive. So now that you have been working with filmless, what do you find to be the downsides/limitations when compared with thin filmed? |

So now that you have been working with filmless, what do you find to be the downsides/limitations when compared with thin filmed? View Quote Thanks John! Honestly, besides price, I can't see any true downsides to filmless tubes. There are a few differences, though, that some people may consider to be negatives. The ion strikes seem to be more pronounced compared to thin-filmed tubes and some people may find that off-putting. It doesn't really bother me and I'm guessing that one of the reasons the ion strikes are more noticeable is due to the reduction in other sources of noise present in the tube. Another difference I have noticed with the two filmless tubes I have is that the autogating whine is considerably louder, which would probably annoy some people. Again, not a big deal to me. Aside from what I've mentioned, I can't really think of anything else, especially now that the other "issues" regarding reduced MTTF and susceptibility to recoil damage appear to have been debunked. So, all things considered, it really comes down to whether the slight increase in performance justifies the additional cost. If I was looking for the absolute best and had an unlimited budget I would choose filmless every time. While that's not the case for me, I've been lucky enough to find some deals and I've been really happy with them so far. I made a video comparing the filmless tubes to my other Gen 3 tubes and I will post that in my comparison thread in a little bit. |
