My attempts at astro imaging

10hrs in Ha on the Cygnus veil supernova remnant

With the nearly full moon about I dont normally image but the weather was just so good, so I cracked out my 10nM bandpass Ha filter and went widefield with my new Altair 70mm to see how it performed.  I managed to get around 10hrs during the week, in 15 and 20 minute exposures.  I was/am intending to supplement with  RGB once another clear night comes round (Assuming thats in the next 6 weeks or so as this is a summer target and is fast dissapearing behind the house).

The veil nebula is one large object with a few separate parts, If you look at the blood moon/eclipse video this was the same setup so gives some idea of the size of object.  It is the remains of a star that exploded in a supernova between 5,000 and 8,000 years ago. Middle left you can see the ‘Witches broom’ – the star with the ‘broomstick’ tendrils(which is probablly the most widely imaged section). Centre/bottom is Pickerings Triangle and on the right is the least imaginatively titles Eastern Veil….
