NGC7822 project

I was aiming to get 3 hours each of Ha, OIII and SII on NGC7822 specifically to show the "Elephants Trunks" or "Pillars Of Creation" within the complex - not to be confused with similar structures in different nebulae.

I then discovered that my OIII was slightly out of focus so I need to recapture when the conditions permit. In the meantime I tried a bi-colour combination of Ha and SII.

Very nice Terry, get the Oiii sorted and you've got a great image.

I finally got some decent OIII on the target. I've been playing around with the image and come up with this. It needs some additional work on removing the cyan rings around some of the stars. I think that may have been caused by deconvolution in PixInsight as I am still coming to grips with it.

I've also rotated the image around a bit so the pillars are now vertical.
