Laboratorium Solaris: PST saves the day
...featuring AR 2524 and western limb proms.
North is up, East is left.
My attempt to use "recently developed" and tested "Barlow-buster" to get hi-res whitelight image of te Sun failed miserably, surrendering to ugly astigmatism. The only element to blame is my whitelight film filter...
So back to little PST, which diesn't let me finish session empty-handed.
And - that is good, if I'm not mistaken - the 800x800 pixels frame, like the one on the right panel, seems to be very evenly illuminated, so maybe flatfield calibration is not that important. Homework task: evaluate this :)
