CaK sun - 21 April


Smerral

Recommended Posts

This morning's CaK sun, shot with the Altair Astro 102 ED-R (stopped down to 70mm) and Altair GPcam V2. Filter was the Lunt CaK B600.  The full disc is a mosaic of 10 panes.  The patchiness is due to me not getting my flats sorted yet. The close up was shot with a 1,5x barlow. 15/300 frames stacked.

How are you doing your flats Brian?

I do it with white cereal box plastic innards covering the scope and pointing at the sun.

I do them in the same way Terry, but I have some plastic stretched over a home made cardboard frame. In this case the clingfilm I used was not opaque enough.  Your idea sounds good though.  I may try using that.
