Re: etx90 (duper542) - Celestron Telescope Eyepiece and Filter Kit, 1.25in

The image reversal you spoke of is completely normal for the telescope. You can use an erecting prism to flip the image back to what the naked eye sees, but this is only really necessary for terrestrial viewing. Also, aligning the red dot finder is a rather simple process and will aid in aligning the scope overall toward what you would like to view. All of the following should be done with a low power eyepiece. During daytime, first point the telescope at a distant land based object (radio tower, treetop, etc. being careful to not point the scope at the sun) and center it in the field of view. Tighten any knobs to lock the telescope in place then use the windage and elevation knobs on the finder to place the red dot over the object in the telescope. Double check that the object is still centered in the telescopes field of view. To finely align after this rough alignment is made, find a bright star at night and center in the telescope. Then adjust the finder so the red dot is over the star. You will probably have re-center the star in the telescope and adjust the finder several times to get it perfectly aligned.
