M81 & M82


Recommended Posts

Hi All:hello2:

please find attached a quick process sample of M81 & M82....something is clearly wrong, as there is some banding present. why that is, i dont know.. the un-processed example is fine, but lacks the detail without processing! anyway, here's how i did it:

Failand 27.4.11 2nd attempt at imaging M81 & M82

Orion 150 6"

Canon 20d

800 asa

57 subs 100 seconds

40 darks 100 seconds

20 bias 1/4000th sec

all 6 camera batteries 'died', so went home about 4am

stacked in DSS

Processed in photoshop 6 & pixinsight

rounded-off with sausage butty, complete with ragae ragae sauce and several cups of coffee!:)

didnt bother going to bed!

hope you like the image, but will hopefully post a re-processed example soon.

Beautifull - one of my favourite sites!

Great to see them in such clarity. Love the whisps coming out of the disk. :)

thanks, but by my own admission, the processing is truely awfull! I'm using pixinsight, and tried following harry's brilliant tutorial on histograms, but it doesnt seem to like my picture!!!
