Hi, has anyone tried 1.5.1 with the celestron AVX mount, and do you have a link to the 1.5.1 version? I can't seem to find it in the software section? Thanks in advance. I am also having major problems guiding and find it totally unnaceptable theat ZWO fob this off so lightly! One of there comments above say will try to fix in the next week, then further down they say by the next release!! This has gone from being a really useful piece of kit to the achiles heel of the entire system and has made my sytem virtually unusable, over the best clear nights I have had in six months! We need to start voting with our wallets and going to other more reliable sources, I know they cost more but what use is cheap when it doesn't work and ZWO won't fix it!!!!!!!!!!!!!!!!!
