Description

Finally reattempted this one, think I may have used a bit much blue but can't decide whether the slightly different processing steps is better or worse. Managed to reduce the star sizes a bit but left barely visible rings.

Old description: An attempt, from last night, at using longer than a minute exposures; wind started picking up part way through on what was a nice still night so I lost a third. Still having some trouble getting the best collimation and focus, but doing better, so much so I think I might actually make this public ....
