The C8 optical tube has a very large focal range. It should be capable of focusing on objects from 15' to infinity. To focus on object at infinity you have to move the primary mirror foward. You do this by rotating the focus knob CCW. Rotate the knob CCW until it comes toa stop them slowly bring the mirror back by rotating the knob CW while viewing the object. It will snap to focus so don't move too fast yor you'll miss it.

LX200 GPS problem

I would suspect the Autostar II controller - the symptom seems like a 'stuck' key that tells the telescope to slew in one direction. The controller can be opened with no problems - just be sure not to lose and parts by doing it inside. The keys are molded rubber that press to the curcuit board to make contact. Clean carefully with a dry lint-free cloth and re-assemble. Note: the red filter on the top end falls out when the case is opened, so make sure it is in place when closing. When testing, make sure the axis clamps are loose so the gears can free-wheel without causing damage. Also - do not leave batteries in the telescope in not being used - the last thing you need is a leak.

I am new to astronomey and I just purchased a used TASCO Starguide 60 telescope at a garage sale. I did not receive an owners/''how to'' manual; but I did get info from this site that directed me to a similar Nexstar telescope; my problem is I do not have a clue as to how to use this scope. The Nexstar 60, while similar, has many differences. I believe that I need to upgrade items(i.e. the hand control) to those like the Nexstar. Do the nexstar hand controls work with the TASCO? If so, is it worth it to do so? Believe me I need a LOT of help!!!

Locate a local astronomy club and attend their star parties. They will help you with the telescope. NO! Nexstar hand controller do not work on TASCO telescopes. You bought a VERY VERY small 60mm telescope. You would have been better off buying 10x50mm binoculars as your first "telescope".

I just set up my Powerseeker 114 Telescope. I don't understand what the CD is for? but, when I tried to look at the sky I couldn't? I don't know if I don't have the right Latitude for Rockwall TX?? or if I just don't know what the hell im doing? which probably is the best of the two love the stars, moon and everything out in outerspace but if I can't figure this out then how can I really appreciate it?? PLEASE, someone help I guess I need someone to help me at least be ableto look out of it.Thanks I'm not sure how I got to this site, so dont know how to get back but my email address is.. I appreciate anyone who can help a goofy blonde in need.

Would be happy to help you since I live in Rockwall, Texas! :)Our next free star party in Rockwall is on Sunday evening May 24th weather permitting at The Shores park.

Need a focus knob for a MEADE ETX-70 TELESCOPE

You can try calling Meade here:

Meade, model: 6600, 6", need instruction manual & eye pieces

Sorry about Meade's responses, but their website has a download section for the telescope manuals - you may not find one that matches exactly, as they produce hundreds of models, but one that is close should suffice. As for eyepieces, there are several good vendors out there; Orion Telescopes, Meridian etc. Just check the barrel size; either .965" (Japanese standard) or 1.25" (American standard).

Cannot focus a Meade Refractor "Electronic Digital" series

All of Meade's manuals are listed here-- it outside during the day time-- put the eyepiece with the LARGEST number written on it into the telescope--- this is the LOWEST magnification.Point it at a distant object and practice focusing-- the moon should be your first night time object.

I have the Nexstar 8. It will not auto align or manual....

You must set TIME, DATE, and SITE-- probably does not know your actual location. Read the manual and perform all of the setup procedures. Some of these have a "starting position" again read the manual and make sure you are in the "home" position before you start the alignment.

Please help. I need the user manual for c-star

That is a very simple reflector style telescope --- here is my suggestions-1. Forget about the barlow--- since this scope has a very small aperture you will not be able to get much more than about 125 power-- if you try to use the barlow which DOUBLES or TRIPLES the power of your eyepieces the images you see will be degraded and it will be VERY hard to point the telescope and focus.2. Put the eyepiece with the largest number (which is the lowest magnification) into the telescope and take it outside during the day and practice focusing on a distant object.3. Take it out at night when the moon is up and LESS THAN 3/4 full-- the moon should be your first night target...... if all goes well try to find Saturn which is up in the sky right now, and appears as a slightly yellow "star".4. The smaller telescope is the finder scope and mounts on top of the main telescope tube. Use this to point the main telescope------- but you must first line it up on a distant object so that the small telescope and the big tube are both pointed exactly alike.5. Try to find a local astronomy club and attend one of their star parties.6. Here is a manual for a telescope that is very similar to what you have except yours is on an Alt Az Mount while the one below is on an equatorial mount but many of the tube parts are the same--
