My first post here for a while. I have a new setup - portable because I now live very close to the centre of Sydney so horrid LP. So here is an ETA taken with a dual NB filter from a couple of hrs imaging the other night before the clouds and rain returned. It is based on 4 min subs with an ASI294. I might have pushed it a bit hard, perhaps it is a bit strong in the Ha but I quite like the result considering I was testing the gear, the new kit is performing ok. I am new at processing these types of NB files.
