This is a narrowband shot of NGC 7822 and the emission nebula Ced214 in Cepheus.

SHO pallete was used, and exposure time was 6:5:22 hours. First frame was 26 Aug, last was 16 Oct.

So Martin, do i read that as 6 weeks 5 days and 22 hours?

Massive effort either way, looks a very fine image, its another one of the i have never seen nebulae that you keep showing us - fantastic
