Returned to image the Sun after a long pause due to bad weather. A small equatorial active region is rotating into view however is still on the limb and today I could not see it yet. Few prominences were visible on the W and E limb while the disc was peppered with some minor plages and filaments. Here are the largest prominences

Very happy of my new triplet objective, really sharp from H-alpha to calcium.

Thanks to all

in the meantime that small active region is now visible at E limb, I can't see if it is spotless or not

Really nice details especially on the limb capture!

Is that a LS 50 or 60 etalon you’re using with your mod?

Super images and setup.
Best regards,

It's the LS50

Thanks for your comments. Confirm, is the LS50 as it exactly fits in the M68 female thread on the focuser tube. A Baader D-ERF is in front of the objective.
