OK i was trying for a flat field evenly focused - i didn't get that. Instead what i got was even more severe curvature in the corners that i had to crop off. So basically it was a test shot - it provides me an insight into what not to do - again LOL. it was a Williams Optics 0.8 Series 3 reducer corrector.
for the record, it was 47 minutes, ISO 400 with cloud about taken with the 127ED canon cooled 350D and the WO reducer. Processed in Pixinsight, shrunk for the web in Photoshop.
Might get out the 8" R200SS tomorrow and mount that up
again after getting the mirror pinching of the primary fixed up provided its good weather
