Sadr Region in HOO

[AstronomyUkraine]

I have been waiting quite a few weeks to capture some SII data for this image, in the end I gave up on the SII, and made a HOO instead. The image has an integration time of around 13 hours.

I combined the channels in PixelMath, using the following formula:

The image was heavily cropped, due to an horrendous reflection on the OIII data from Sadr. An upgrade to my Optolong filters is needed, I  would like Astrodon, but will settle for Chroma. I have heard very good things about them.

That's nice ?

That look like what I would imagine hell to be like if there ever was one, lovely detail Brian.

I use Chroma filters and am on my 3rd year with them now after using Optolong which I found horrendous for halo's.

Chroma used to make them for Astrodon, so you really can't go wrong with them, try and buy them direct as they will be cheaper.

Thanks John. The image originally looked a bit dull, and muddy looking, so I dropped out some of the blue in PI with the CIE *b component in curves, and replaced with yellow. It transformed it.

Thanks for the tip about the Chroma filters. I notice a lot of imagers choose the 3nm SII and OIII filters, but use the 5nm Ha for some reason, any idea why?

I really don't know Brian, I use the 3nm on all of them and really am impressed.

Thanks for that John - just what I need.  I have lots of Ha + OIII and no SII.
