I recently enjoyed images by
@Michael Feigenbaum and
@John Favalessa where they used
@Frank Breslawski's "crazy" pixmath HaOiii formula for their respective images. I was pushing my luck trying to get O3 with 85-90% moon with the RASA8, but thought it was worth a try and the result was definitely gratifying for the limited integration time.
My standard HOO process was struggling and I couldn't get the project to come together. I relented to returning to get more data later, but I thought I might try the crazy formula........wow!!!!! What a cool effect on this image.
I also have been using a star reduction technique where I stretch and combined non linear data. Then I remove the stars and complete sharpening, saturation, curves, etc. Then I go back to my linear combined image and stretch it with GHS at 1.5 stretch factor and around 9-10 local stretch intensity. I then take starnett2 and remove the limited stretched stars and add them to my edited starless image. The results have definitely been a step up for me in my option.
When I finally got to the end, all I could see was a velociraptor from the original Jurassic Park emergening through the mist with it's right arm and leg as the darker nebula in the lower left.
WR-134 is a star located in Cygnus 6,000 light years from Earth. These unique types of stars occur when a main sequence star is running out of it's hydrogen and starts fusing heavier elements. The fusing of heavier elements releases huge amounts of energy resulting in surface temps 20,000 to 210,000K compared to our soon at 6,000K. This increasing energy also causes stellar winds push the outer hydrogen and oxygen shells out in a rapid manner. The crescent nebula, dolphin head nebula, and Thor's Helmet are other examples of type of stellar life cycle.
