Hello all,

Recently I have been thinking to implement dithering to my mount to remove walking noise, but my mount has a declination backlash, around 3 seconds or less. So is it okay to disable the dec guiding, and let APT and PHD2 dither in RA? I have heard that this will introduce more noise to my DSLR images. Another solution is to try measuring backlash in guiding assistant and guide in both dec directions, will it give good dither results under backlash compensation in PHD2? What do you think?
