Hello,
Has anyone been using the celestron star sense autoguider?
I have one and it is a nice bit of gear, the only problem I have is balancing the dec axis. When the mount is balanced in dec and ra the ssag tracking is great in the ra axis, the dec axis has a massive run out leading to star streaks in images and could not work out why.
Then I changed cameras from pentax k3 monochrome to a zwo 533mm camera and forgot to rebalance the dec.
Started tracking and the dec tracking within limits getting good images, for some reason the ra axis balanced, the dec axis nowhere near balanced and getting great images.
Anyone have any comments as to why this would happen?
Regards,
Wombat
