Putting a few milestones up to give you some orientation:
- choose what to image (nebulae, galaxies, planets, moon, sun)
- pick equipment suitable for the object type (there is no one fits all)
- understand what data you need and how to get it (calibration frames, actual object, camera settings, etc.)
- shoot your first images
- understand the general processing workflow that consists of pre and post processing
- pick the software. It can be two different programs for pre and post or one software that does both
- do the pre procsssing
- if you succeed upload the unprocessed stack and post a public link, the community will process it for you and give you feedback on the data quality
- if you fail doing the pre processing upload all your files (that is a lot of data!) and someone will help and give feedback
- learn post processing and try to resemble the examples from the community
- fine tune whatever needs to be tuned, follow the advice, get more processing skills, find your own style.
That is a 2-5 year time table. You have done the first 2 steps so far.
In Nico Carver's video you can see different pre and post processing options. Most people start with free Deep Sky Stacker for the pre and use Photoshop when they already own it or try free Gimp. Dedicated software is not free but much more fun to work with as it is made for the task.
The beginner recipe for a stunning first image is this:
- pick a large and bright object like the Pleiades or the Great Orion Nebula or the Rosette Nebula or the Great Hercules Cluster
- image from a dark place if possible. Don't image when the moon is up. Dark sky is by far the most efficient booster.
- pile up several hours of total imaging time. Rule of thumb: for twice the light pollution level you have to quadruple the over all time!
