I did all four of the visible Hydrogen Balmer lines today (June 9) for the first time. Hydrogen beta, gamma and delta are all fairly similar. I made an animated GIF to highlight the differences between Beta and Delta (which is located quite close to the Calcium H line). For a full description, see my longer post here viewtopic.php?t=41154.
