    USE TINY movements of the 3 collimation screws-- and recenter the star after every screw turn. You want a "concentric" star image that is not PINCHED on one side. Any bright star can be used to collimate your scope.

I used the collimation eyepiece to collimate my telescope.But I dont know if it's properly aligned. The knobs on the bottom of the tube are turned fully clockwise, and the black dot in the eyepiece is...


Before you do anything else, take the scope outside on a good night, find a semi- bright star (Polaris will do). Let the scope cool down! (about 45 minutes) use your highest power eyepiece and put the star in focus.
Now take the star out of focus (inner focus or outer focus) you should see a dark circle in the center with symmetrical rings around it (airy rings). If the dark circle is in the center and the airy rings are symmetrical, your telescope is collimated
Check both inner and outer focus, they should be close to the same. If not you should re-collimate.
Best done with fainter stars but for now stick to the brighter ones.
Because I own 3 scopes, I use a Hotech laser collimator. its quick and easy. Worth it if you travel with your scopes to dark sites

A good guide on how to collimate

Collimation screws on the Celestar C8


If you are going to replace them contact "Bob's Knobs" and order the replacement thumb screws. Makes collimation much easier, no Allen wrench needed.

Problem wirings for Pioneer AVH-P6500DVD Car DVD Player


very easy fix. you can pay thirty bucks on ebay and buy the bypass kit or make it yourself. but the light green wire on the harness has to be hooked up to ground. just hook the light green wire to the chassie of the car and you will be able to see dvds all the time. If you want to buy the kit its not really needed I have a toggle switch on mine just for turning it on and off when I am driving. simple as putting a wire from your chassie of the car(Ground) and then the other from the unit(light green wire) to a switch. hooking it up from Supply to Acc on the switch.

Teach me pls...


hello!

-- who is your internet service provider
-- what is the operating system of your computer?
-- is this working fine before or is this a brand new router

you may try this and see if this help solve your problem. make sure your computer is directly connected to the router

Step 1: Shutdown the computer.
Step 2: reset the router while power on then Unplug the router’s power cable.
Step 3: Unplug the Broadband modem’s power cable and wait for 30 seconds.
Step 4: Plug in the Broadband modem’s power cable and wait for its lights to appear stable.
Step 5: Plug in the router's power cable once the modem’s lights appear stable.
Step 6: Power on the computer on and configure the router settings
Step 7: test the Internet connection.

if this still didnot work, upgrade the firmware of your router

note:

configuring the router settings will depends who is your provider. if your isp is dsl you need to configure your ISP username and password on the router. if your router is a cable no need to change any settings on the router. it should automatically work


if you are still having trouble configuring your device, call supportrix and use supportcall as your promo code for 1 free technical support.
