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

Lovely solar images, the data looks fine to me despite the compression, thanks for sharing with us.
Supposedly another large AR just behind the limb and coming into view in the next few days and we have a forecast for some sunny days this week.
