I am not sure of the exact 'on band' definition but I think it is where the contrast and definition of filaments and AR are most pronounced - if you tune too far you can be off band - Paul will give all the proper explanation.
Looking forward to more of your work!

Paul, to me all comments are allways welcome, so please don't refrain yourself to comment and criticize my images.
As for the etalon tuning, you might be right although I do my best to get both etalons tuned targeting the best resolution possible, but no question that I might be off for a bit.
That is why I hate these mechanically adjusted etalons, where so critical adjustments rely on mechanical pressure applied manually, having just the image on the monitor as the feedback for a proper tuning.
I can't help to say that this is one of the reasons by which I love my Daystar Filter with its precise temperature control to tune the center frequency of the filter. I am getting a proper focal reducer to be used with my DS filter so that I can do full discs. Once I have this figured out, I will sell this Lunt.
Thank you for the comments.
Fernando
