Make your own M20 narrowband pic

Here is my humble try at this picture.

Jase,again, a very nice rendition, striking colour.

Sorry, perhaps I should have mentioned the Ha is binned 1*1 (image scale 0.92 arcsecs/pix) 140min and the other 2 are binned 2*2 (1.84) 50min, as I had in mind Ha as Lum from the start. Thats why the stars are pixelated in this pic I guess ;-). I also double the res before processing (Im not sure if you did), tends to smooth things out. The stars look better than your 1st effort.

I have found in the past SHO is often the most attractive, perhaps because we are used to seeing Hubble shots as the standard.

The inverted layer mask is interesting, have only used cumbersome fancy layered selections when filtering.

Sub 2 arcsec (RMS?) is a worthy pursuit, excellent work if you reach that ;-).

Thanks
Fred

Hi Mill

Hey, humble?, top work, close the conclusion I came to, cant be that humble hehe.

Stars have just a slight NB halo hint to them, sweet. If you havent done much Astro CS gear, this is a fine effort, youve pretty much nailed it.

Hi Fred, thanks for the chance to play with some great images like this.
I had a quick go in Maxim but had to crop it a bit to get it down to the right JPEG size.
I'm thinking about a set of these filters at the 13nm level so it was a great opportunity to play with this type of data.

Cheers

Nice one Ric. It looks weird upside down, ive looked at it too many times ;-).

Cheers
