Planetaries and a galaxy

Howdy
Had a good nights imagine last night. I used a different technique, this time using rather long exposures, of up to 20 minutes each.

NGC4631, the little planetary in Corvus. 3x20 mins iso400 for an hours total, UHCS filter used. Ive not seen colours like that in it before.

IC5148, I was stoked to get this planetary this deep, with the strange pattern inside. 2x20 mins ISO 400, UHCS filter

PN G321.6+02 and he2-120 , G321.6+02 is the fainter one on the upper left and in the UKST Ha survey is described as a "Very bright axi-symetric PN". When using Star Atlas pro to locate it, I noted another PN could be fitted into the image, He2-120 and is much brighter, a pretty little red ring at upper right. I suspect these objects have been rarely imaged in colour before. Its 2x20 mins ISO 400 UHCS filtered.

NGC6818, a bright bluish PN, 2x5 mins ISO 200, UHCS also masked to enhance inner detail.

Finally this isnt the LMC through a 50mm lens, its Barnards Galaxy through the 10 inch scope, 2x15 mins ISO 200 only uv/ir filter used. Looks like a tiny copy of the LMC.
All images through 10 inch F5.6 scope, modded 350D camera, hand off axis guided.
