Comparing 0.6x and 1.0x field flatteners

  1. Just arrived today is 0.6x Altair Lightwave field flattener – to replace my 1.0x version on my mono astrophotography setup – Altair 183M camera, filter wheel, field flattener and Sky Watcher Equinox Pro 80mm OTA on EQ6 mount.

I am making the change to increase my field of view and increase number of visible stars for Deep Sky Stacker, which keeps complaining that it can’t stack more than one file due to inability to detect enough stars.

The images below show the differences in field of view when I took photographs from bottom of my garden today of the solar panels on my roof.
