NGC7000 with OSC Hubble

[silentrunning]

Well I'm imaging more than collimating and fixing now that the RC seems to be behaving itself after the various mods. I got 10x600s on the Mexican part of the North American Nebula with my OSC QHY8L and put it through a number of actions I have written to extract NB data. I then put it through the Hubble pallet colur transforms...

Details and colours are very nice indeed

well done

That's a very nice image. I have a QHY8L and I would be very interested in having a go at processing using the Hubble Pallette. Care to share you methods/actions?

Hi Bill

I have written actions to remove the stars and to seperate out the RGB channels of the OSC image. I then use the R image as H and the G or B image as O. I use a clipped copy of the R channel to simulate S. I then play with the level of the HOS images and combine back into an RGB image with RGB mapped to SHO. I then apply the hubble colour transforms that can be found on the web and Bobs your uncle! It works surprisingly well. i checked the spectral response of the QHY8L bayer layer available on the web and this added some technical kudos to the approach as the H and O signals fall nicely into the R and GB responses of the layer. I also use a Astrononik CLS filter to get rid of LP that would otherwise ruin the whole process.

Thanks for that, Doug. I've had a go on one or two images and I'm impressed with the results. Thanks for sharing.
