M101 and friends from SGL8

Recommended Posts

First Galaxy of 2013 and 5 NGCs :)

Taken with a 7D and 600mm f4 lens at f5.6

30 x 4 minute, 30 x 2 minute and 30 x 1 minute lights at iso 1600 plus 3 x 20 darks and flats and shot in raw, Processed in DSS and then PixInsight and PS

It could be better if I could process this stuff properly but I'm relatively happy with it

Very nice. Especially for 3.5 hours total. Taken with your 600L? :)

The stars look like the lens have been stopped down a tiny bit, you didn't run it wide open? Or you get that effect wide open as well on that lens (asuming it's the 600L)?

it was the 600L f4, I stopped the lens down to f5.6 to improve the corners slightly. Normally I forget and shoot wide open :)

reworked after plenty of advice :)probably somewhere between the original and the rework is about right

Really nice seeing M101 with a bit of room around it, nicely done Kev. I prefer the first version I think, is the second version a touch magenta? and maybe slightly over sharpened? I know its all subjective though:)

I need to control the wavelet processing more and yes there is a touch of magenta in there

Nice one Kev, there's a lot of interesting fuzzies around and very nicely captured. Wish I was there on Wednesday! The galaxy colour looks better to me in version 2, but the background seems to have crept up a bit.
