Thanks David. I really appreciate your comments mate. I started out with EAA using ALT-AZ and thought it was quite acceptable, but eventually started to get the feeling that field rotation was losing too much of my field. I had never done a polar alignment before and always avoided drift alignment because I'm fairly time constrained. I finally bit the bullet and used Sharpcap for my polar alignment in EQ mode and it was so easy. Why did I wait so long? What a chicken! I'm glad I finally took the plunge as I can now take longer exposures, and it's brought out so much more colour in my shots. Whether or not it's the right colour is another story. All of my previous ALT-AZ short exposures (15s and thereabouts) had a green cast that I just couldn't deal with. Longer exposures give results that are significantly better than what I was getting in terms of colour and detail. I guess there's a point of diminishing returns under my skies but so far so good.
I'm eyeing on the Optolong L-Extreme now but worry that I'm going to start fighting with colour again given that it's narrowband. My CLS and OIII filters give good results, but the colours are terrible with my OSC. Have you tried the L-Extreme for EAA before?
