Hello everybody,
If one have enough time to invest (balance, (auto)tuning, polar align, pointing file, this mount is tracking perfect. But believe it or not - the last time at comet imaging I was under extreme time pressure. I assembled the mount, made a roughly balance by hand/no motortuning, pointed with the laser to Polaris, moved to the comet (8° altitude!), started a local tracking - send it to autoslew - and all the images have been perfectly tracked :_) an impressive performance under these circumstances!
best regards
Gerald
