Hello all,

first (Ha)HaOIIIOIII attempt for me. The colors results of layers combination can be funny ;)

But here's a serious one :D

Ha :10x10mn - 5nm Ha Astrodon filter
OIII : 10x10min - 5nm OIII Astrodon filter

Telescope : '86 Epsilon160 + Audine Kaf 1603me .
Mount : em200 Temma2Jr
Location : Haguenau (France)

Pre and post-processing with Iris 5.55.

Hope you enjoy it ;) Sorry for the slightly lenghtened stars, the roof is not always rigid enough :(

Nice shot Pierre.....one more of the galactic zoo:)

Nice shot. Easy to see how it gets its name--unlike many of them. There is one interesting thing I noticed and that is if you look at the green channel there is some nebulosity below the stuff showing. It's very obvious if you bump up the green channel with curves in photoshop. However this is very faint in the red channel, so there really is some green (presumably OIII) light that needs to be brought out.

Thanks Allan ;)



pleased that you have discovered a DSO ;)



Thanks ! Yes, our universe is a zoo, i often tell it also.



Thanks, the picture is designed like this :

- luminance : Ha - rich -
- Red :Ha - rich
- green : OIII - poor -
- blue : OIII - poor -

The OIII channels have already bumped with a log (see iris software), if it is again enhanced, too much noise appear :(

I miss a SII signal acquiring ... maybe this next night :D

Clear skies
Pierre.
