The Dumbell-ED 80/Canon 300D
I had a go at imaging this showpiece Northern object on sunday night, with the ED 80, canon 300D, using an astronomik CLS fillter
seeing Robbie and Scott have been pushing the envelope in terms of exposure i tried to go as long as i could..went over an hour in terms of total exposure, but had to dump some frames -must have lost a guide star or something
anyway my polar alignment was bad so had heaps of field rotation over this period. However IRIS was able to rotate and stack the images, and also remove much of the gradient.
Each exposure was around 6 minutes at ISO 800. 48 minutes in total.
Comments welcome....
