Hi folks, Bill here
I've got a flattener that is giving me (slight) 'Star Trek warp speed" shots (see
https://stargazerslounge.com/topic/1...tener-reducer/ and my test shot at
www.flickr.com/photos/skogpingvin/35322362416).
Question - from the images in the stargazerslounge thread, I'm too close to the flattener. But can anyone tell me if it's possible to tell HOW MUCH too close?
