Hi all, here`s a ponder for you all, i have been collimating my scope a heritage 130p , now this is a fast scope, i have collimated it and now it is slow scope? the mirror are not offset has described in Astro Babys guide at the end of the article, so the question is will the mirrors align offset anyway when collimated, ie because of short tube scope . Or is it i have done it wrong? i have done the star test and it looks ok to me, but.... the images just could be a tad sharper? yours paul.
