The sun in Ha and CaK 23/09/17

[DrRobin]

Hi,

Clear (ish) this morning, so managed a few snaps in Ha and CaK.  I tried something new, shooting in 16bit and then sharpening in Astra Image using deconvolution.  New methods always take a bit of getting used to, but the results are looking good.

All images William Optics GT102, ASI174MM
