Yet another M51 -a bit like London Buses

Recommended Posts

Taken around the end of March.

L = 18 x 600 sec,

R = 13 x 600 sec,

G = 13 x 600 sec and

B = 15 x 600 sec.

9hr 50min in total.  All binned 1 x 1.  Capture SGP and PHD2,  processing with DSS and Photoshop.  I've fiddled a lot with this image and found it dificult to know when to stop.  Focus could be improved but I'm waiting for the new Celestron motor focuser.  The trouble is they keep delaying the release in the UK, AND putting the price up!

Nice one, lots of diffuse detail in the outer limbs. I know exactly what you mean about fiddling with the data, I have just spent another 2 hours messing with my M51 image, but my eyes and head hurt now, so that will be it for a while.
