Daniel, glad I'm not the only one getting lost with spectrum. I'm still trying to learn with what i captured over a year ago (before my stroke, capture is now too difficult for me).
Ken is very helpful and i keep rereading the threads picking up little gems (didn't realise AstroArt has a spectra stack feature, gave up using AA when I moved to Pixinsight, but feel my stacking could be much better still). Hoping the SA100 and ZWO is good enough to record usable data to get a handle on spectrum. Got a feeling this will be a never ending process trying to understand this better. getting distracted by minecraft doesn't help
I'm more of a learning lurker with spectrum but i've learnt much from Ken and his book (just want to find time to reread and work through my own data together and take working notes etc), so thanks heaps Ken!
