July 29, 2024: Full disks is white light and Ca-K again (at last)


Recommended Posts

Finally found time and sunshine to set up the APM 80mm F/6, and take some images with the ASI178MM. First with the Herschel wedge and Solar Continuum filter, best 500 out of 1000 stacked (yet, the seeing was pretty stable), postprocessed in ImPPG for sharpening, flipped vertically in GIMP:

I then inserted the Lunt Ca-K module and processed in much the same way, except for my usual play with curnes in GIMP

Ca-K, grey scale:

Ca-K, pseudo colour:

Pretty pleased with the results. Lost of activity to enjoy. I am still stacking the batch of H-alpha data I grabbed.
