Hi,

I'm thinking about getting a barlow or telextender, and I'm just wondering if I need to take into consideration 'flat field of view'....

I'm very much a beginner, so it would be mainly for visual observing in my 8" F6 dob, so is there anything I should be aware of? I think I've read somewhere that, for visual, a flat field is not really ideal....

Thanks,

Stephen
