What exposures did you use? Are they seconds or minutes? It wasn't clear in your description. Are you also using a coma corrector?


Thanks for the kind comments Eamonn (and everyone).

The exposures are in minutes.
L= 30 x 5 min (No binning)
R= 10 x 3min (Binning 2x2)
G= 10 x 3min (Binning 2x2)
B= 10 x 3min (Binning 2x2)

Regards and Clear Skies,

Picture postcard perfect there Dave,
The "ireland" outline is very prominent as is the pulsar itself!..

Dave,

I always enjoy looking at images of the Crab Nebula. Being an emission nebula as well and a member of the Sharpless Catalog, I would have advised you beforehand that all of your luminance data be shot in either H-alpha or Red, for it makes a dramatic difference (obviously) and really brings out the tendrils.

Very nice Dave especially given the LP problems you have. If earth hour coincides with a clear night in Dublin can you imagine all the phone calls the next day asking about those strange lights in the sky. :shock:
