IC 1499 (california nebula) with OSC camera and Ha/O3 filter

Hi Richard, you did a really good job on the image. Unfortunately my Pier 5 membership didn't last long enough to get the datasets. That's why I'm all the more pleased to see a finished image.

Hello Richard, 

Thanks for the link to that thread, interesting. :) 

I recall an attempt on pier 14 many, many moons ago to image ngc1499. The oxygen was so weak that you ended up posting a HSS image instead. That confirms just how demanding an o3 target this is. There are suggestions in the thread on things to try, but I wonder if using less ha integration time when combining might yield any improvement at all. If so, then for such targets much more integration time might be needed just for the o3.

Nice image Richard!  Pier 5 really showing its power in bringing a lovely "3D" texture to the nebula and a super clean background...

Regarding boosting a faint O3 signal: recently one of our fellow members on RS put me on to Bill Blanshan's NarrowbandNormalization script. This has really worked wonders in "bringing the blue" to images taken from my backyard OSC setup.  The companion video does a great job explaining how to implement the script and what the various settings are for.  Simple and powerful really...

Hi all

From memory 1499 is also strong in Sulphur so using the SII/OIII dual band actually gives you two bites at the O3 cherry whilst collecting the signal for a SHO palette.

OSC CMOS tend to be less sensitive in blue anyway

There is plenty of time left for gathering data on NGC1499 so why not try SII and get some bonus OIII. What you got to loose at F/2.8 speeds :)

Done. Jobs 2430 and 2431

Thanks Ray. I will check that out.

Hi Richard 

It was Anunnaki who posted that useful information about the NarrowbandNormalizationScript from Bill Blanshan, so I too want to thank him for making me aware of it as well. If it enables you to pull more of the oxygen out without the need for more integration time, perhaps you'll post a newer image for us. 

So much new stuff these days it's hard to try and keep up.

Cheers, 

Ray
