Re: AR3615 - X-flare on 23Apr & M-flare on 24 Apr (Singapore) [New Images Added]

Nice additions Alfred, I believe the bright points you are talking about are called penumbral grains, and represent material welling from deeper within the sun aligned with the magnetic field lines. There's bits and pieces about them online but not much.

Re: Achieving Focus with a Zenithstar 61mm and Quark Chromosophere

Quark is designed to work with a 2" diagonal which has optical path length of about 130mm. So, if you use an 80mm extension tube and rack the focuser out about 60mm you should be in the right ball park.
