Hello;

What are your thoughts on Owl Services new barlow? It's not listed on their web site yet. Would such a barlow correct chromatic aberrations bred into acromats? HMMMMMMMMM

My thoughts...

Barlows do not correct for Chromatic Aberration in Achromats nor do they correct for coma in a Newtonian.
