Is this differential flexing?
Hi guys,
I am trying to do some deep sky astrophotgraphy with my 12.5" f/5 reflector and a new auto guider attached to my scope with a small guidescope but I am still getting lots of trailing.
Part of one of the images is attached - 5 minutes on Eta Carina
It's an auto-guided exposure at a focal 1600mm focal length. There are three distinct blobs of the star in the trailing which suggests the autoguider was guiding ok but then lost the star.
Does it look like flexing? or poor polar alignment?
A bit like a detective story I guess.
