Hi Magnus

Quark chromosphere is very demanding in terms of seeing due the strong amplification factor of the internal telecentric, you need a fairly still air to obtain some decent results. Try on the morning or in the evening within two hours from sunrise or sunset respectively.

As far the imaging technique is concerned you can find many discussions in this forum that can help you effectively. This article by Alexandra

https://solarnutcase.livejournal.com/18572.html

is an excellent starting point.

For H alpha I usually stack 300 - 400 frames out of 3000 by using of Autostakkert, the raw image is then processed in IMPPG or IRIS. Be careful to shield your monitor from direct daylight, it would actually need to be well in shadow otherwise accurate focusing becomes challenging.

Thank you! I am only getting about 50-70 images stacked so far. I will keep on working on this. Thanks for your encouragement, and useful advice, I appreviate it.

Magnus
