Eta Carina NGC 3372

A while ago I picked up a De-rotator cheap and finally have been able to attach it to the scope, it works ok but still has some issues the bearings are wobbly so after some research it seems I will need to get slightly larger ball bearings to reduce the wobble and sometimes it stops working for a while then restarts not sure why, so I still needed to crop the image to remove the curved stars.

10 x 3min subs unguided at iso 1600
