A side note here, linking back to my own thread linking the photosphere to the chromorosphere and also apparently the zone of ionization where calcium atoms become singly ionized..

I just try to show the beauty of the night sky, and again the possibilities with a smartphone. There are already better applications at the google play to make the night lapse easy. At first I used the Gif maker pro. It's a good app to edit the frames, before creating video, but you can't save the videos in good quality. Now I use the TimeLab app (same developer, as Intervalometer app), in the editing it has not so many options, but with this app you can save the videos in 4K too, or full HD. This video is 360 frames (each 30 sec exposition at ISO 800) Huawei P10 monochrome camera, Intervalometer app, TimeLab app. Pictures taken in Kleinwalsertal, Austria 2019. 09. 23-24. (The video is full HD, I don't know, why, but it doesn't run continuesly on my PC, when I watch that back on SGL. I hope, on your monitors you can enjoy it!)

I’m looking to do Milky Way Astrophotography, and I’m hesitating on whether I purchase the Full Frame camera that is the 5D Mark II or the APS-C EOS 600D.
I plan on using the Rokinon/Samyang 14mm F/2.8 wide angle lens, although I’m open to suggestions so long as said suggested lens is under 500$.
The mount I use will be the iOptron SkyGuider Pro with the counter weight supplies in the set.
If there is an alternative to the cameras listed above that goes for less then 400$, I’m willing to hear it.
Thanks a bundle,
