DaliborGrubacevic Nothing wrong with using the telescope in the daytime, or even
GOTOing in the daytime. "Faking" the alignment is acceptable; the better the location and
date/time values the better the first alignment star GOTO will be. And of course, the more
accurate the initial HOME position (base and tube level, and the OTA pointed to True North), the
better the initial star will be centered. You can then just press ENTER to accept the (invisible)
star as centered. Same for the second alignment star. Of course, the same applies at night but at
least you can correct for any alignment star pointing errors.

DaliborGrubacevic Since a Magnetic Compass points to Magnetic North, you need to
correct for your local "Magnetic Variation", which can vary from 0 degrees to about 20 degrees
depending on your location. Once you know where True North is on your horizon (can you see
Polaris at night?), you can then just point the telescope to that location on the northern horizon.

Hello,
I currently own an etx 125 and Im wondering if anyone knows where I could get a replacement thumb screw. Im referring
to the thumb screw that holds the eye piece in place. I've been trying to figure out what thread it is but have been
unsuccessful. Any help would be greatly appreciated. Thanks

ScopeStuff.com has replacement screws for almost everything telescope related. Or, if you have an old
computer cable with screws on the connector, one of those screws should work.
