Does that mean you can't rotate the camera though?

Hello,

I have a Williams GT81 with 166.7mm back focus and a Baader Herschel Wedge that eats up 114mm of it. The Focuser takes 55.8mm by my measurement. So the imaging plane is ~5mm inside the clicklock The drawtube is wound all the way in and I have one lens that reaches focus.

I'm thinking of replacing the 47mm long, 2" Baader click lock with the T2 version. I have the T2 ring that correctly holds the ND 3.0  and Continuum filters. So * I think * I just need the T2 Clicklock to solve all my problems! - a shorter path, a clicklock and the T2 surface to stop the nose of my camera/eyepiece from hitting the filters.

I'd be grateful for your feedback

Can you tell visually (white light or Ha) what the polarity of the spots is?

I understand a little of Hale's Law and Joy's Law (or think I do!  ).

Typical, nothing much to see the last few sunny days, tiny AR appears along with clouds / rain.

May well be the start of 25 as I believe new cycle spots start low on the disc then gradually appear higher up as the cycle progresses.

Fingers crossed.

 I thought they started closer to either pole and then appear towards the equator as the cycle progresses. New cycle spots have the opposite polarity to the old ones but I have no idea if you can tell that visually. Would love to know the truth of this!
