Astro Photography Tools & Stellarium
A quick question with regards to Astro Photography Tools and Stellarium.
I’ve just downloaded both and I’m currently in the process of configuring both.
With regards to configuring gear and, more specifically, the telescope, do you need to add the actual focal length of the telescope or the effective focal length once the flattener/reducer is attached?
