Polar allignment routine with equatorial wedge on Meade LX scope

Post by mioxzy » Fri Aug 09, 2019 10:15 am

Until now I have used Sharpcap with great satisfaction with my telescope (Meade LX90) in altazimuth configuration. Wanting to take a step forward I got the equatorial wedge, I assembled everything correctly but at this point I'm not sure how to perform the polar alignment routine with the fork mount on the equatorial wedge in Sharpcap. To complete the second step in the routine it is required to rotate the axis in right ascension by 90 degrees, but in doing so the telescope points 90 degrees from the polar :( . How can I proceed further? Definitely something wrong in my procedure.

Thanks for the support

Hi,

I must admit that I've never used a wedge to turn an altitude/azimuth mount into an EQ mount, but as I understood it the wedge tilts the mount so that what was the vertical axis of the mount points towards the pole – thus your azimuth axis becomes the RA axis and the altitude axis becomes the declination axis.

If this is right then the starting point would be with the scope pointing straight towards the pole (would be pointing towards the zenith if the mount was still in altitude azimuth mode). From this position if you rotate the RA (azimuth) axis through 90° then the scope should still be pointing towards the pole.

Hope this helps, Robin
