Reducer Comparison

A comparison of different reducers, same target and scope. Scope was an Orion 80mmED, focus was set by using a STI stilleto focuser and camera was a modified digital rebel. Exposure was 5 minutes at ISO 400. The target was the double cluster, NGC 869, in Perseus.

Jim Solomon (from the OrionED list) was kind enough to put the images up in a fashion to do a rollover to compare the cropped images. That page is located here: http://www.saratogaskies.com/articles/ed80-reducers/

It is obvious to me that the WO focal reducer/flattener gave superior images.
