Re: Apertura 10 x 50 Right Angle Finder Scope (RACI)
The other night I wanted to see how the Apertura RACI performs at higher powers. 6mm Baader Classic Ortho (BCO) produced a nice sharp view of 70% lunar phase at 33x. I could not detect any CA . I stepped up the power to 74x using Baader Q-Barlow 2.25x. The view of the lunar surface became dimmer and softer, and yellowish ring of CA became apparent around the lunar disk. However, I was delighted to see that there was plenty of helical focuser travel to accommodate Barlow/BCO combo.
Next time I will try some brightDSOs and doubles. I should try a zoom EP to. But even now it is clear that this RACI can function as an ultralight telescope.
Next time I will try some bright

Mine has arrived, along with other goodies.
