Description

Solar observers =xv78j7mAkihiro Yamazaki and Osamu Oshima have both recently posted fascinating images of the chromosphere recorded in the extreme blue light of H-alpha. In both cases, their Daystar filter power was either off or had just been turned on. Having an interest in imaging in the blue wing, I did a little qualitative experimenting to see if my Daystar ION H-alpha filter would behave similarly. The filter bandpass is 0.8 Angstroms and intended primarily for solar prominence viewing and imaging, but can be used to record filaments and active regions on the disk with more aggressive post processing. The attached series of photos show the results. The top 3 photos were shot as the filter was warming, the bottom two images were recorded at -0.5A and center wavelength
