There are so many aspects to "astronomy" that there many to enjoy and explore whatever your skills and interests. Its also a hobby that lasts and isn't a fad tied to current technology or age. So there are great people of all ages and experiences willing to share their wisdom. Actually sharing is a big part of astronomy, if you spot someone outside with a telescope they are more than happy to let strangers come look through the eyepiece and have a chat.
It's also a science where mere "nobodies" can make new discoveries or contribute to research. It doesn't need qualifications or special equipment, just a willingness to look, learn and be a part. We have people here who have discovered supernovas (and probably more), people who teach, as well as simply people wanting to look up.
I think patience is one of the best skills to have. We have ALL had the same setbacks and disappointments that newbies face. As well as wasted money on things we didnt need because we were impatient, we have the fun of clouded weeks following the purchase of a newtelescope (its a subclause of Murphy Law

To address your original question, I agree with Ken its not the correct question. [edit] Actually Pluto's post is my thoughts exactly, I mostly use PixInsight and very rarely photoshop afterwards but 99% of the time its PixInsight (PI) from source raw images through to a jpg to put online. I also do photography so I use PS for that as its the best tool, but for most of my astrophotography its of no use. But grab yourself GIMP as its free and you can make use of it anyway for regular photos and star trail landscapes. If you have a camera you can do astrophotography right now, you dont need telescopes or tracking mounts, they're just a matter of reaching small targets and improving your processing options but are not a requirement. Most of mine is camera with lens from a regular tripod. Once you start trying, you start learning.
