Title: New TS Flattener test
Post by: mickw on Nov 28, 2011, 08:04:03
Tried out my new TS Flattener at Rother Valley over the weekend between clouds and gales.
All single subs and "auto levels" in PS, no other processing, and scaled to 1024x683
M16 is an earlier image without the flattener but is in focus unlike the others  :oops:

I think the flattener has made quite an improvement but the spacing still needs to be sorted and also some flexure in the focuser - running out of back focus  :-?
