Hello,

Another very nice clear night last night.With the moon so bright I decided to shoot some more Ha,this time the Cocoon Nebula.

You won't be able to tell from the image but seeing was actually very good!Unfortunately after the first 3 frames I fell asleep and did not monitor focus,the subs became very soft at about #9.

I took 600sx18 and used them all,despite the soft focus.Deconvolution helped tighten the stars back up some.

Probably need to shoot it again with better focus but here's what it looks like at 55% of full size.

Thanks for taking a look,your comments always welcome.

Nice Jason,
Looks like you got the dark lanes that spoke out from the cacoon too.

So I guess the focus got soft due to temperature change? I have had that happen before and I was looking right at it (unattentively I guess). I couldn't even say I fell asleep 8) .

Great image - I can't really tell your focus was not optimum.
