NGC281 - Work in Progress


Recommended Posts

I decided to stick with The Pacman nebula after the Ha data I'd gathered a while ago was so useful looking.

This is Ha and OIII only mapped Red and Green respectively. There is no Blue channel. It is not finished. I still need SII and more Ha.

I had a decent night last night though adding nearly 4 hours of OIII data.

Looking good so far. My first reaction was "woah too yellow" until I read the words. How does it look if you put the same OIII data into the blue channel? HOO is an accepted palette, and IMO often gives a nice result, because it seems to give a better distinction between the hydrogen and oxygen. Excuse me flogging my own thread, but here are the results I got from using HOO, and then introducing the SII.

I feel that putting the OIII data into the blue channel does nothing except add a blue tint. As in narrowband imaging you have total control over the colours if you wish I don't see the point of putting the same data into two channels. I might just as well have two lots of data in two channels than three.

Just my thoughts

Blessed with clear skies last night that were not forecast. Not a good time of year though - the air was quite wet. Roll on those cold, frosty nights!

I managed 4 hours of SII data last night. This is the result thus far. Still need more time ...... one more clear night might do it.

WOW !!!

... this is one of the best renditions of this object, that I've ever seen !!!

I was listening to Mozart's Piano Sonata No. 11 in A major, K.331 - as I was viewing this. Try it. Catapult to another world, among the gas and the dust so vividly showing in your lovely, lovely image !
