Weather has shut me down so I've been revisiting some data from last summer. Here is M27 with its outer shell. I got better color balance this time.

That outer shell is really remarkable in your image. It is interesting how it is not symmetrical or distributed like the overall shape of the nebula.

Great image!

Very Very nice photo that outer shell really shows its size and complexity of the Nebula-Outstanding! Clear Skies

I have seen other images of this nebula but never with with such detail of the outer shell. It stands as a great reminder of the detail available in long exposures.

Kind regards

Very nice! Incredible extensive outer envelope there!

Is that the scope you gave away :surprised

Hi Mike,

Thanks. Yup, that's the scope I gave away. It did "ok" with an KAF3200 chip but not so good with my KAI11000. The scope had more than one problem; one of which was very asymmetrical flaring off of bright stars -- possible a severe turned down edge. I never could get the supplier to acknowledge anything. Never the less, I think the MakNewt design is the greatest overlooked design for astroimaging. I would like to try one again, but only if I can get a higher quality scope.
