M11, M13, M17

Hi all,

Yesterday the moon was at 85% illumines but I've mange to get some decent images from the city:

M11 - 100 frames 4 second each:

M13 - 100 frames 3 second each:

M17 - 100 frames 13 second each:

Although the polar alignment was almost perfect their is a drift in the RA axis and because of that I can't take longer frames than 15 seconds!

Does anyone know how to fix the freedom in the axes?

Thanks,

You may need to adjust the meshing of the RA worm and gear to improve the drive to the RA axis. It may also help to keep the mount slightly heavy (doesn't need to be much) on the east side so the worm is always driving the RA gear.

Thanks James! I'll try it next time.
