With the C90, I tried for this a week ago and the collimation had shifted so the diffraction rings were askew and as a result the companion was lost in the mix. Last nite I corrected the collimation spot on and here's Izar proper through the aligned system. The 8" newt by comparison naturally shows a smaller airy for both stars and greater color in both with the companion like a blue spark of light . Later on I got a beautiful Epsilon Lyrae but that's a drawing for another time. They were cleanly split with magnitudes showing their slight differences. Delicate views.
