NGC6543
The Cat's Eye planetary nebula in Draco. The dimensions are about 25" by 20". The Officina Stellare ProRC 700 is an excellent instrument for this object, but a lot of exposure time is needed. This photo represents only 30 minutes, and the processing was difficult. I would like to add many more 5 minute frames. SII frames yielded virtually no contribution.
