Hi


Attached are some images of the sun taken at Ha wavelength on the 23rd June.

As usual, imaged with a ED100 telescope + home-brew spectroheliograph and ASI183MM camera.


Frames reconstructed using Doug Smith's SHG_Main software.
Best 12 of 31 frames selected and stacked with AutoStakkert3!; the resulting image deconvolved in Astrosurface.


Seeing was quite good given the low altitude of the sun atm.


I have also included a frame reconstructed from the same data in the continuum about 2A away from the Ha line to identify the sunspot groups.
Unfortunately, all data heavily compressed here..



Cheers
Maurice
