AstroScope Night Vision Module For DSLRs

Adequate light has always been a problem for picture taking, which is why someone made the mistake of inventing the on-camera flash, spawning generations of washed out pictures filled with creepy red eyes. A much better way to go about taking pictures in the dark is with a more sensitive lens, but the more sensitive the lens gets, the bigger it has to be DSLR Battery Grip .

You can get around this practical limitation by cheating and using electronic enhancement, and the Electrophysics AstroScope 9350EOS-FF night vision module makes this just about as easy as possible by mounting snugly between your DSLR body and the lens of your choice. You can use telephoto lenses, macro lenses, tilt-shift lenses… The AstroScope preserves all the electronic connections between your camera and your lens and just sits there, amplifying photons as they pass through. It works just fine with image stabilization, draws a minimal amount of power from your battery, and is available for both Nikon and Canon DSLRs as D40 battery grip and EOS Canon EOS 450D.

As far as price goes, Electrophysics thoughtfully answers that question in their FAQ:

Is the AstroScope expensive?

The AstroScope 9350-series products are cost effective modular solutions. We designed the AstroScope with modularity in mind to save you money and to “build in” a level of forwards compatibility Nikon D300 battery grip0  . You can take advantage of the unique opportunity to “swap” our patented Gen III AstroScope common module Central Intensifier Unit from one night vision imaging platform to another (for example, use one CIU for both a camcorder and an SLR camera setup).

The only other problem with this night vision module is that it turns the whole image that exciting high-tech military fluorescent green color like Canon EOS 350D battery grip , which might cramp your style if you’re trying to, say, take pictures of animals at night. The solution, of course, is to go find animals that are green to begin with. Like, polar bears.

Battery Grips for DSLRS

I recently made a fairly significant addition to my digital camera kit - a Canon EOS 5D. Ever since I’d tested the camera for a few weeks last year I had been dreaming of getting one of my own (and saving my pennies) so when I had enough money saved up I grabbed one.

Also rounding out the purchase was a new Flash and a Battery Grip.

While I thought long and hard about buying the camera body and the new flash the Battery Grip was something of an impulse buy. I’d previously always invested any spare money into new lenses and hadn’t thought about a battery grip - but there was an option to throw in the grip (and an extra battery) for only a little extra and so I decided to give it a go - thinking that I’d probably only use it if photographing an event like a wedding.

Having had the new camera, flash and grip for a six weeks not I can honestly say that I’m extremely pleased with each of the purchases. The 5D is a dream to use. My only complaint is the slower frame rate in burst mode. I’m also loving the ability to go extra wide with my 17-40mm lens now that I have a full frame camera. I’m also starting to wonder if I should buy a lens with a longer range than 200mm (as it has less impact on the full frame sensor than it had on my old 20D). I’m also loving the flash - it’s producing some great results and now I have the ability to set it up in a slave setup with my old flash I’ve been experimenting with some interesting lighting for portraits.

So the 5D and EOS 300D battery grip the new flash are great - but what has surprised me most is that I am really loving the battery grip. In fact instead of just attaching it to my camera for special events, I’m finding that I’m using it all the time.

My wife thinks I do it because it makes my camera bigger (and boys like to have big things - hmmm…. that didn’t quite come out right) and that I’m just showing off. Perhaps she’s got something there, it does make the camera look more professional - however I there’s a few other reasons that I love my new BG-E2N battery grip:

1. More Power - two batteries instead of one means recharging half as much. I find that Canon DSLRs have pretty good battery life at the best of times but after a couple of weeks of medium use-age shooting with the 5D I realized that I’d not had to recharge once (a new record for me). It was also great when shooting my son’s birthday party last week. No hunting for and changing batteries at key moments!

2. Second Shutter Release Button - I knew the Canon BG-E3 battery grip had a second shutter button and setting dial but didn’t realize how much I’d use it in my photography when shooting in portrait mode. It’s not that I ever found shooting in portrait mode difficult before - but this is so much easier (or am I just imagining things?)

3. Weight and Balance - two batteries weigh more than one and the grip itself adds a little weight and size to the camera. While this could be seen as a disadvantage (and I’m sure it would be in some circumstances) I really love it. I feel like the camera is sitting well in my hand and that I’m somehow more solid when taking shots. I’ve read people argue about battery grips helping combat camera shake and previously didn’t see how something heavier in a hand would help - but again I ‘feel’ like there might be some truth to the argument.

The only real downside of the BG-E5 battery grip is that while the extra weight and size feels good, it could get a little tiring - quite literally. I did shoot with my 70-200mm f/2.8 IS lens for a few hours last week. It’s not a light lens and with the extra weight of the 5D (as compared to the smaller and lighter 20D) plus the weight and size of the battery grip I did feel like I was lugging around something pretty significant.

New battery can not be fully-charged

Generally the new battery can 100% fully discharge-charge. Last month I buy a latitude d820 battery replacement, as my work dont need to take the notebook out, so I use the notebook with the AC adapter and I store the battery in my drawer. Last Friday, I want to visite my customer with my notebook and show some business projects. So I charged my battery for a whole night, but I only see my battery 70% capacity state charged next morning. My battery is really new, why it can not be 100% charged?

So I query the battery expert Jack Smith that the reason “Why new battery can not be fully charged?”. He said that : after the laptop battery not use for a long time, the battery charge must in the low current in the right system power option. And then he give me some adviese to set the power Option. Now I introduce the tips for my readers step by step with detail photos.

A .windows xp system:

1) Go to Start/Control Panel/Power Options and look for the “Alarms” tab.

2) Choose Low Dell CF623 battery alarm and critical battery alarm to make the alarm operation to no operation untick the two boxes(see below picture)

3) Let it discharge the battery till the laptop automatically off.

4) Charge the Dell D820 battery again.
Attention:Do as below:

B: Windows vistar system:

1) Go to Start/Control Panel/Power Options/Edit Plan Settings /Battery/Low battery action/Do nothing.

2) Let it discharge the laptop battery till the laptop automatically off.

3) Charge the battery again.

In the end if you still cant fully charge your laptop battery, you can calibrate the battery and then use the battery fresh program to refresh your battery to calibrate the battery charge-discharge time.

Notebook battery fully charge and discharge error

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of laptop battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of latitude D800 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion inspiron 8600 battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the inspiron 630m battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a GK479 GD761 battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the VGP-BPS5 battery’s “charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the HP DV2000 battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the Satellite A100 battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full laptop battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.
