Spot on pictures

There is a blury spot on lcd and on pictures which is quite diffuse without magnification but becomes smaller and more distict when the zoom is used. I have cleaned the exterior lens but to no avail. Could dust or something got inside the lens housing? and if so, how hard is it to dismantle and clean the lens assembly? Thanks

How To Use A Spotting Scope For Shooting

If you practice hunting and shooting, a spotting scope is one of the best instruments that you need to have to provide you with a clear view when you are aiming at your target. Before we get started on how to use a spotting scope for shooting, it is great if you know what exactly a spotting scope is.
Precisely, a spotting scope is a small device that is used for many outdoor activities to magnify and help you watch images and objects closely. Before purchasing the best spotting scope for shooting, you need to know a few things that will help you use it well in your shooting career. Here are some things that you need to know when using a spotting scope for shooting.

Comfortable Position Is Key
If you want to get the best performance from your spotting scope, ensure that you position yourself in a comfortable place. You know when you are using a spotting scope you will be holding it for long so it is very crucial to find a comfortable place that you can sit or lay down depending on what you find best. Make sure you find a comfortable place and learn more about the specifications of the area which should be the point of targeted area.

Attach Your Scope To A Tripod
Sometimes holding your scope with your hands can compromise the quality of images that you get because of shaking and fatigue. If you want to achieve a clear and accurate view, get a tripod and attach to your scope. This means that your scope will be very stable because there are minimal movements so you end up getting very accurate results. When you are using a tripod, the chances of missing your target are very minimal.

Adjusting The Magnification
You should also adjust the magnification of your spotting scope to a level that you like. Spotting scopes are designed differently so you need to know how to adjust magnification and the lens layout of your scope. For the most accurate results, it is great if you read the instruction given about the magnification levels and how to adjust.
In some spotting scopes, you need to use the lens knob so that you can zoom in and out of the magnification. In other scopes, you need to use the small zoom in and zoom round trigger on the point of the eyepiece.

View Target Area And Adjust Magnification
When you are using spotting scopes, it is not advisable to go with the magnification first because you might not get the right results. The best thing that you can do is to view the target area first and then adjust the magnification effectively.

Reset Focus In A New Area Always
This is very important because a sudden highly magnified glass can cause problems to your eyes. This means you can feel uneasy when you are watching your target longer. This results because of watching at a very high magnification glass for a prolonged period. You can overcome the problem by reducing the effect of the magnify glass on your eyes.

Beating The Sun
If you want to become a spotting scope pro, you must learn how to beat the sun. You need to know how to deal with the frustrating heat waves because they quickly distort your view and it becomes difficult to grass. The best way in which you can beat the sun is to zoom out. Zoom out to a lower power setting and you will enjoy heat-wave glassing hours. You should wait for passing cloud because they reduce the heat wave and give you the chance to zoom back in your target.

Final Words
Buying the best spotting scope for shooting is not enough. You also need to learn how to use it so that you can get clear and bright images all the time. This will help you gain accuracy when you are shooting so no more missed shots. If you learn these tips, you will not experience any problem when you are hunting or shooting. Knowing how to use your scope is the only way in which you will get most out of it when shooting. Best Spotting Scope to buy in 2017 Buying Guide Reviews

Just bought a starnavigator 114. Purchased a Barlow lens to use with my 26mm lens, but with the barlow I can't see anything. Do I need to make changes in the lens config. in the Autostar?

The barlow may be too much magnification for that aperture telescope. The higher the magnification the SMALLER the sweet spot is in focus.

Turn the knob slower and also practice focusing during the day time on a distant object.

Grey cloud

This sounds like a diffuser problem. Basically the LCD Panel is defective.

32" LCD TV use about 8 horizontally mounted flourescent bulbs. They use a plastic material that diffuses (spreads) the light from each bulb evenly on the screen. If this Diffusion Material becomes wrinkled it will leave a grey cloudy look on the screen.

It is possible that the LCD Panel Glass is defective buy honestly I would guess the diffuser.

This isn't cheaply repairable and it is better to replace the TV unless you are experinced with Electronics repair. There may be a possibility to pull this material out and replace it with something readily available from Home Depot but I have not tried this before. It is possible to pull this from another LCD TV.

Large yellow spot in center of tv screen

Sorry, but there is no cheap method of repair for this unless it is in warranty.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.

Good luck.....

DSC w5 has a spot in every picture

Assuimn there is nothing on the lens[I would not think this is the case as it would not show as a distict spot Not ne fora DIY or a repairshop this is a a failure of the CCD. Depending on the age of the camera and model this may qualify for replacement, as there was a reported CCD issue at one time Either that or Sony may offer a replacement at a good discount.
