With the moon much less of a problem a clear night attracted me back to IC 63 with the main scope. Lack of cloud allowed a good run of subs for a more detailed image than was possible with the apo. Details: 10" F 4.3 Newt. 10x 10 minute exposures @ iso800 with CLS in DSS, CS2 & XAT.

Pete,
It's interesting to compare this image to the earlier iamge taken using the apo. Despite the use of the CLS filter in both instances the hue of the nebulosity appears different. Also, it looks like the background is somewhat darker in the image taken with the Newtonian.
Do you think these differences can be attributed to the processing, the sky conditions or simply differences between the scopes themselves?

Simon,
It's mainly down to the processing. Just a nudge on the hue control in any of the photo software will change the colour. The background darkness is usually affected by the contrast setting. I guess it all depends what your taste is at the time! For some reason I usually find myself processing wider field images lighter.
