    IC 1848 "The Soul Nebula" in HST palette

    Hi all
    I've almost recovered from my laryngitis and there was the promise of some clear weather last night so needs must as they say and I just had to get out and take some pictures. I decided to tackle IC 1848 as I hadn't tried this subject before, I was aiming for 2 hours per filter in 10 minute unguided subframes but as is usually the case with the British weather there was a couple of periods of cloud which wiped out 2 of the Ha and 1 of the OIII subframes. For the rest of this imaging run the seeing wasn't very good, I could just about make out Cassiopeia as the sky appeared a bit misty, this was confirmed by the noisy image and gradient on the image when processing which I think I have managed to get rid of the worst through processing (so please excuse the over processing). I colour combined the image as an LRGB combine using the Ha data as a luminance channel and then asigned SII=Red Ha=Green and OIII=Blue with a weighting of 3:1:2 for the respective RGB channels. Some people may say that this is wrong to use the Ha as a luminance channel when there is already Ha as a colour channel and this doesn't give a "scientifically" correct image, but I don't image for scientifically correct images I image for enjoyment and because I find the results pleasing. Anyway, that is enough of my ranting, I hope you like the image
    Thanks for looking
    Best wishes
    Gordon

    Nice.

    In my opinion a photo is what the photographer wants it to be. If the viewer wants done differently they can take their own image. So no apologies needed for how it was put together. Each method has its advantages and disadvantages. There is no "The Way" as I see it.

    Lately I think your English weather has moved my way. Nothing but murk for weeks now. I still have a few old images to process however. Seems I much prefer the imaging part to the processing part!

    Gordon -- Beautiful shot.

    Rick -- the hunt better than the cleaning, I suppose
