Hi,

I am studying how to focus with my Baader Maxbright II on my Newton 250 f4'8 telescope. The fact is that of the various options being considered, I have seen the one attached in the photo, that is, the 2.6X Baader GPC connected directly to the binoviewer. Has this option worked for anyone? Otherwise, apart from a 1.3X OCA from Siebert (very expensive), could the Barlow APM 1.25" ED comacorrected Barlow 2.7x be used successfully?
As always thanks for your help.
