From my perspective the two pictures do not have a big difference despite the colour tone which of course depends on the post processing. However, it’s interesting to compare the results with respect to their total exposure time: The image recorded from Boeblingen was exposed more than two times longer.
Finally I combined both images to one final image by rotating one image until it matched exactly. Maybe I am wrong but I think in the end this combined image has a little more detail than each of the pictures alone.
A full resolution image is available here.
The sun recorded through an 8″ GSO Newton telescope (with solar filter), a 2x barlow lens and a QHY5L-II-M camera. The black dot in the middle is a sunspot. I used the Registax tool create a stacked image. The image is also available in full resolution.
