some testing in narrow band H-Alpha.
During the night July 06/07th, I took the opportunity to try to do some narrow band H-alpha images having in mind that the moon rises close to 22:00 UT hoping that this will not impact narrow band imaging to much. I selected Cirrus using my 150/1340mm Refractor and tried to do a mosaic out of 15 single images. You may "dive" into the full resolution image - Warning: 6MByte! Time and weather permitting I'll increase depth and/or add more colors.
