Cool!
Are you limited to 30 second exposures, or could you go for more 10 second integrations?

Hi Paul,

I'm limited to the field rotation of the scope and the light polution. Near polaris the rotation is bad, and NGC6543 is near Polaris, hence the need for a wedge.

The light polution in the back garden limits me to 15 second before the flood lights go out then about 30 seconds after (field rotation).

So move house and wedge, simple answer.

Pretty good structure in that. Should be interesting to see what you can bring out with the Barlow.
