Fine tuning Tak EM200
Posted 07 July 2009 - 02:09 PM
Two things I noticed:
1) On the altitude lockdown, it doesn't matter how much I tighten the lever, the mount will still move up and down (as seen in the polar scope) when I turn the altitude adjustment key. Is this normal?
2) On azimuth, sometimes when doing a precision polar alignment, (using WCS alignment software), the star shifts to the west as I begin move in that direction, then as I continue to turn azimuth knob, the image begins to go back in the correct direction. Also I noticed there are little indentations on the azimuth peg on the tripod (I am assuming these are from tighting the azimuth screws). Should I loosen the azimuth peg, and rotate it 90 deg or should I leave wellenough alone? (although the "southern" post hole on the tripod is completly round it is doesn't look like there is a way to set the peg perfectly "square" with the northern leg of the tripod.
last thing. Once I get azimuth precisly polar aligned, should tighten both azimnuth knobs against the post, or leave a litte gap and just tighten the mounting bolt (underneath tripod)?

Work fine for 30 minute exposures for me.
Can't help you with WCS since I use PAM, but not all the time.
