Hystogram Stratching with Live Stacking of the Sun
Posted: Wed Jul 05, 2023 8:30 pm
Hi! I,m a new entry.
I take public astronomy lessons at the public observatory of Specola Chiavacci in Pieve del Grappa, Italy.
We have a Coronado telescope to observe the sun, and we are collecting its images with a camera ZWO (ASI 178MC), projecting live images into a big wall monitor.
My question is the following: is it possible to show the sun details of prominances and cromosfere both at the same time?
I checked it is not possible with a single shot, due to the big difference in light levels of these different reagions.
I also tried using live stacking, and working on the hystogram stretching, but the controls of the stretching are not sufficient.
I know that the software ImPPG gives a very powerful tool to stretch the hystogram, with many control-points along the transformation curve (see attached Image).
I dream the possibility to apply this stretching technique to the Live Stacking process, in order to show live a very powerful image of the sun!
Can you suggest me anything similar ? Thanks a lot!
