M101 1/2

[Rodd]

A preliminary HaRGB image.  With about 1/2 the blue and no Lum (I used the sharpest channel, green, as a luminance).  I gave high hopes for a good luminance and better blue.  This is Bin1, but it should be bin2....I forgot

C11 Edge with .7x reducer and ASI 1600: red 170 120 sec; green 121 120 sec; blue 60 120 sec; Ha 90 300 sec.

Here is a Bin 2 image without using a synthetic luminance like I did in the first..  Long way to go!

here is the final version of this limited data set.  Rained for a week and tomorrow is supposed to be clear--but Moonlit.  So Ha for me.  Either more for this one, or another.

I very much like these renditions, which have a dramatic lighting. There's a strong feeling that we're in the depths of space. I also think the colour is great. You've not been draw into overloading the blue so your colour resembles professional images.

Thanks Olly!  Saturation has always been a concern for this target.  For some reason color was easier to handle this time. Maybe it has something to do with focal length/aperture?

I added the data from a TOA 130 shoot from a couple of years ago.  I wanted to see if I could boos the signal in the dim areas.  Not so much--but it did improve the image overall.  Still need to collect C11 data (blue, Lum and maybe Ha)
