as some of you may know, I have a new 6" refractror. my new scope has a 2" star diag and a cheap (short tube) barlow. I also have an Orion "shorty" barlow from my 80mm. the question(s) is: does it matter (performance wise) where the barlow is placed, i.e. either bewteen the OTA and te star diag vs bewteen the star diag and the eyepiece? I can tell from using my 80mm that the image is magnified more when the barlow is between the OTA and the star diag. Is this the correct placement? the reason I ask is I am considering a new barlow for the 6" and I dont know if I want (need) a 2" etc...
again thanks for any comments.
