Re: Quark Chromosphere - no image at all

Hi Jochen, looks a familiar experience first time Quark use. Wel if on a dual mount one scope point to the object, does not necessaraly mean the second one also does. (Cone error between the scopes). With the Quark the fov is very small, and also I had troubles finding the Sun first time. Also Quark...

Thanks all for the comments.
Just busy now taking new images, and yes the spots are getting smaller, but some new pores seem to appear around it.

Will publish the results later today.

Re: Daystar 127mm aperture fully integrated Solar Telescope

I wouldn't want to pay $8k for a Quark grade scope
Neither would I. I have a 120mm scope, so for that price could probably buy 7 quarks (and get bulk discount?) and hopefully get 1 good one.

Re: FD 03-30

The green line represents the sorted to quality.

Jochen are you sure about the "sections". Doesn't AS stack accourding the the sorted quality? (Thats the only way thats make sense)

Re: Some new activity

Thanks Mark.

I used astrosurface for the stacking but did not use the wavelets of other filters. That was done with IMPPG, which gave me better results. (but i could have settings wrong in astrosurfacce.

Re: FD 03-30

I would say its fixed pattern noise too. But that is strange, never seen that on an AS120.
To much undersampled? What f/ratio did you use Maurits.

Re: SM2 Etalon, Primary vs Double Stack Module?

Sorry Mark but I don't take that statement and don't understand why we still take such an attitude from manufacturares. I know making etalons is not easy, but if you shift quality control to consumers (and hope you sell it to less knowlegdeble people) well that is NO WAY of doing business!
