To Barlow or not to Barlow
Hello again
Recently i've been looking to acquire more eyepieces. But I have come to the question "is a barlow worth it"? There seems to be speculation over if more lenses is better than having a barlow. I have an F5 scope and it appears that a barlow can assist in some of the issues with wide angle lenses and fast scopes. However there has to be some draw backs to it but I cannot find any real reason to not go with a barlow lens.
Is a 12mm scope 2x barlowed the same as a 6mm? do barlows really affect the performance of the lens attached to it?
