2009 Imaging Competition JANUARY WINNER
My two panel mosaic image of Rosette and Cone Nebula is a January winner
in Northern Galactic, an international astronomy community for professional and advanced astronomers, scientists, astrophotographers and science writers.
-
The image is now in the running for the 2009 Grand Prize.

The California Nebula, NGC1499
-
-
At night of 25.02.2009 I shot more lights for NGC1499, the California Nebula,
to see how deep I'm able to go.
-
Original narrowband color image can be seen here:
-
I borrowed O-III and S-II cahnnels from there and added them to new H-a channel to
boost it with, otherwise missing, wavelenghts.
After that I used this O-III and S-II boosted H-a image as a new luminance over the the
original.
-
Original data can be found behind the link, new data is:
13x600s8, Binned down 2x2 + 4x1200s, Binned 1x1 with Canon EF 200mm @f1.8.
I haven't been able to find any information about this formation.
It looks to me like an old Planetary Nebula?
If you have any information about this, please, leave a message.

I add here a small animation about processing steps of the O-III channel.
Information in this channel is very dim and a special threadment is needed to reveal it.
In attached GIF-animation normally stretched O-III image is not showing any obivious shades.
When stars are removed image can be stretched very differently, since I don't have to
care about bloating stars.
(In narrowband imaging Stars, as they are broadband targets and contanes no relevant information, can be removed.)
In a final stage of processing all stras are returned, with a special tecnique, with no data lost.
The animation is a gropped from midle of the O-III image.

Sh2-240 as Stereo Pair
Ones more I have redone this Supernova remnant Stereo precentation. I wasn't happy with it before, now it looks some how better, I think.
