      Adam Block was very kind to lend me 28 hours of 5 nm Ha captured from his 32". The moon apparently was up for much of that, but nevertheless there was noticeably more Ha present then what I could capture with no moon and only 6 hours.

      A "deeper" image was produced later when the skies cleared in Julian, CA...
