WO 0.8x focal reducer/flattener - thoughts?

Hi guys,

Sorry, this is not a thread about IF I should buy one ect

Just asking if anyone else uses a WO 0.8x FR/FF to correct curvature, I've been using one lately with an ED80 however some nights it seems to work better than others. Last night I imaged a chunk of the LMC (including NGC 2070), and the edges of the image look a little suss (stretched, elongated stars). Where as other times I have used the WO flattener, I've had a nice flat field in the images. Any one else recieving random results like I am
