Yukon NVMT 2x24 Gen 1 - Answered Questions & Fixed issues
Extended viewing distance when fitting a external
well its a gen "1" unit so any extra "ir" light will help out a lot! i use a deban gun light 50 watt buld with an "ir" filtter fitted to the light i can see nearly 1/2 mile and i can just about target a rabbit at no more than 100m with my sight set at x5,,,(3-9x50 with a 30mm bore) there not all there cracked up to be,,you loos a lot of light going through the scope,
to have a good night sight you need to go to gen 3!!!! so you need to sell your sole to buy one!!!

Hello, don't worry about it. It is HV to the image intensifier tube. The battery
voltage goes through control circuit then to ccfl inverter (here is were dc
voltage is switch on and off and switch dc voltage is step up by toroid coil
that has two input and only two out puts). By impulsing the coil with two
different switch dc voltage on the input this make the current lag the two
different phase voltage by 90 degrees. Here is where the strange noise is coming
from. The toroid coil is encased in iron case and if half of this iron case is
loose, it makes case vibrate so the noise.
Now, the voltage come out of the toroid coil is switching dc (one could call
it AC because that what AC voltage is, it switch between positive to negative)
this voltage is about 300 to 900 switching DC voltage. This voltage will be
applied to a 1/2 wave voltage multiplier (this voltage multiplier with have
anywhere four four stages to 10 stages depend on what the input voltage to
multiplier is.
Low the voltage out of the ccfl inverter the more stages the multiplier will
have.
Now, the voltage multiplier will double the voltage per stage to need image
intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever
one wants to call it. This voltage will bit you but it doesn't have a lot
current associated with it, the current would be in the 10 to 15 ua (micro-amps)
1/10X6 amps.
Now, you know. GB...stewbison

I need firing order for a 1981 Johnson seahorse 115
its just 1-2-3-4- with the port bank being 2-4 starting at the top and the starboard side being 1-3.
They're all the same be it V-4 or V-6. 6=123456

Cross hairs do not adjust. Tell me what to do please?
All question need FULL 'make model (what it is)'.
You posted to optics, so let's guess is a telescopic rifle sight?
It is impossible to see and movement as the crosshairs move such a tiny amount. Half a millimetre in the sight is 10 feet at the target. The only way to zero in sights is on a fixed bench rest at the range.
If you really think they are faulty, return them to the maker for repair.

I have a NexStar 90GT with no hand control, a replacement will cost $135, is it worth it to buy for this telescope?
Whether or not it's worth it to buy a replacement hand control for your NexStar 90GT telescope depends on a few factors:
- How often do you use the telescope? If you use it frequently and rely on the hand control to find objects in the sky, then it may be worth it to invest in a replacement.
- How important is the hand control to your observing experience? If you're comfortable manually finding objects in the sky and don't necessarily need the hand control, then it may not be worth the expense.
- Can you find a cheaper alternative to the official replacement? Sometimes, third-party sellers may offer hand controls that are compatible with your telescope at a lower price.
Ultimately, it's up to you to decide whether the cost of the replacement hand control is worth it based on your individual needs and preferences.

I have a Whirlpool clean top stove with a cracked stove top. Can I get a replacement top & is it easy to install or do I need a professional to install it?
Yes, you can get a replacement stove top for your Whirlpool clean top stove, and it depends on the model and the availability of parts. You may contact Whirlpool customer service or check with a local appliance parts supplier to see if they have the replacement stove top in stock.
As for the installation, it will depend on your level of experience and comfort working with appliances, as well as the specific model of your stove. Some stove tops may be relatively easy to install, while others may be more complex and require professional installation.
Generally speaking, installing a replacement stove top can be a difficult and complex task that requires a certain level of technical knowledge and expertise. It's recommended to consult the stove's user manual or contact Whirlpool customer service for assistance with installation instructions or to find a professional to do the installation.
