I just received New Star 4SE. In Iraq with the army and cannot see anything thru the view finder. Batteries are in and hand control functions. Caps are off. Scope will adjust with hand controller


First you must line up the small finder scope with the main tuibe--

Point the scope at a distant object like the top of a telephone pole. Center the top in the eyepiece of the main scope-- then without moving the scope center the red dot on the same exact spot on the telephone pole.

Also practice focusing on a distant object during the day time-- use the eyepiece with the largest number written on it and DO NOT use the 2x barlow if you have one. Turn the fopcus knob slowly until the object comes to focus.

Tip

You Just Bought an EQUATORIAL Telescope Mount!


Even though we warned you not to do this, you bought one anyway! Beginners should never buy an EQ telescope mount as their first telescope. It's too late now; so I guess we will need to teach you how to use it!

Equatorial mounts move in a way that seems not to very intuitive. Unlike the easy Alt AZ mount which moves up and down and left and right, the EQ mounted telescope seems to move in TWO dissimilar directions at the same time.

Additionally you must first polar align the mount on the North star Polaris before you can use it. SEE! we told you not to buy it!

Here are the steps to roughly polar align the telescope so you can use it. If it is motorized the single Right Ascension motor will keep the sky object inside the eyepiece for long periods of time. If you do not have a Right Ascension motor, the slow motion RA knob can be slowly turned to keep the sky object centered in the eyepiece.

Begin by leveling the mount and tripod. Move the entire mount and tripod so it is pointing roughly to North, as close as possible using the steps below or a compass. Don't forget to adjust for your magnetic deviation. My location's compass reading is about 5 degrees away from true North. This is called magnetic deviation. You can find your location's deviation on the internet. Then proceed with the steps below.

First, adjust the Declination to the latitude for your observing site. Declination is the angle that the scope is pointing UP, and it's the same as your latitude. For example Dallas, Texas is about 32 degrees North latitude, adjust the scope so the small indicator reads 32 degrees. By the way, the North star in Dallas, TX is about 32 degrees above the horizon. Your latitude matches the elevation of Polaris (the North star) above the horizon.

Second, either look through the polar alignment scope buried in the axis of the telescope mount, or look along side the axis, and get the star Polaris lined up in the cross-hair of the polar alignment scope, or as best you can by looking along the side of the mount axis, or lining it up using your compass.. This will put the scope to within about 3/4 of 1 degree of the TRUE North celestial sphere. This is good enough for VISUAL observation, but NOT good enough to do astro-photography..

Adjust the DECLINATION up or down, and move the entire mount left or right until you can see Polaris as indicated above, or it is lined up as close as possible.

Now you are roughly polar aligned. Now you can move the tube around by loosening the Right Ascension lock, and or the Declination lock until your sky object appears in the small finder scope mounted on top of the main telescope tube.(DO NOT MOVE THE MOUNT, and the counter weight should never be higher than the telescope tube) Lock down the scope in both axis and use the fine adjustment RA and DEC knobs to center the target. Again, DO NOT move the mount or tripod. The mount should still be pointing at Polaris.

This web site illustrates this procedure:
http://www.astronomy.net/articles/4/polaralign.html

also this web site

http://www.telescopes.com/telescopes/polaralignmentarticle.cfm

You should be able to keep an object within the field of view of the eyepiece by slowing turning the Right Ascension slow motion control knob-------- IF you are actually accurately polar aligned. Small adjustments may also be needed with the DEC slow motion knob since you are not exactly polar aligned using this rough alignment technique.

However it can be used successfully for visual observation. Your scope will now track the motion of the stars as they move across the sky.

Hope that helps you!

Clear Skies!

I have just assembled the Tasco 70x 800 refractor, but there does not seem to be any way of adjusting the altitude. There is no knob to loosen the mount, only a nut which is hidden inside the mount which...


There appears to be a KNOB underneath that you loosen or tighten -- and also one on the altitude. Adjust these knobs so that you can move the scope but with some friction---here is the manual

When I got my 10" unit it was locked at the base


Look, after all of what you did and you cannot get anything to work you need to ask for your money back. Did you buy this from eBay? They do have a buyer protection plan. Obviously you did not get what you paid for. Even though you took it all apart it is quite defective.It must have set up too long in extreme conditions such as an attic or storeroom. If indeed it was checked out before you bought it only minor defects would be visible. This is just a suggestion Sir. I know it is not a fix and I'm sorry this happened to you.

HI, Just purchased a nextstar 8 and when I tried to view thru the main eye-piece, nothing. Even tried to look at the full moon, nothing again. Yes, all the lens caps are off but it seems like the focas...


Check the focus knob and make sure the small "set-screw" is tight and the knob is just not spinning around on the shaft.

DID you turn the knob enough to focus? Sometimes it may take 10 - 20 full turns.

Finally the focuser is attached to a "rod" inside the tube that moves the mirror back and forth to focus the scope. It could have come loose from the rod?

Instructions for disassembly are here:

and here:

Balancing a 70mm refractor tube


Looking at pictures I found on the web, I see a knob on the bottom that tightens the scope to the dovetail bracket on the bottom of the scope. First attach all of your eyepiece then loosen that knob and slide the scope back or forth until it will balance without tightening the knob. Or if you do not have the manual you can download it for free here.

Focussing


All of Tasco's manuals are on this web site-
http://www.tasco.com/pages/instruction-manuals/

Put the eyepiece with the largest number written on it into the focuser-- do not use the 2x barlow if you have one. Practice focusing with this eyepiece during the day time on a distant object like a telephone pole or a building.

Focus Issues


Try tightening the grub screw that fastens the knob onto the shft that it turns.

Better still, buy a flexible extended focusser which makes focussing much easier. Check on eBay for "Meade flexible focus"
