M101

[rfdesigner]

Hi

I'm slowly getting the imaging a little better... last time I shot m101 was on film.

anyway

29 x 4 minutes with the 383L+ on the 12"

processed in IRIS.. really needs Photoshop or PixInsight etc.

any advice welcome

nowt wrong with that

Very nice, you've got loads of signal and good resolution, too! The stars have dark halos, I'm guessing this is from your star layer? If so, a quick curves should fix it...

Thanks Lewis

I used two lots of of deconvolution, one algoithum that leaves a slight halo and one that leaves a dark ring, by balancing them I've manage to somewhat balance their impacts. As I don't yet have a coma corrector I'm finding deconvolution starts to break down away from the centre of the image as the star profiles change.

as I said.. I really need a full blown processing package... and a coma corrector.

Very nice

Thats a good attempt, this is a difficult galaxy to image, very very faint...

thanks.. you're not kidding about it being faint.. I can set my camera to 8x8 binning, making it effectively 64 times more sensitive to broad objects. I was running 1 second images in 8x8 when trying to find the galaxy to image and it hardly showed up at all, I could only confirm I'd got it with 4 second images.

I should add, this is my first 'fast asleep image' taken while I was in bed... makes domestic life a whole lot more acceptable.
