For me the biggest learning curve has been dealing with all the different software programs for capturing, stacking, and post processing. I currently use smartcapture for capturing, Autostakkert 2(AS!2) for stacking, Registax for wavelet and/or color adjustment when needed. This has been the best combo for my skill level (newbie) and scope setups. All these programs are free and there is lots of good tutorials online and people on cloudynights forums are quick to help. Most of it is trial and error to see what works best for your equipment and seeing conditions.
