JeffMorgan If there is no such thing as “too much capability” then why not a 2600?
IMHO, you do not need a 2600 to take pictures that these beginners will be (are) taking. You can see lots of example of crummy images taken by the 2600 by the neophytes on the ASIAIR Facebook page, while you can see plenty of great images from a simpler 12 bit camera on Astrobin.
It is much better for the beginners to start with a simpler camera. If they start with the 2600, they would never know that while the amp glow is suppressed in the camera, the amount of hot pixels is astronomical [sic]. If you want to learn, start with the basics.
I may be jaded because I started in the hobby by grinding my own mirror back in high school in the 1960s. I have gone from using film (Tri-X, Dektol generation), to webcams, to DSLR and mirrorless cameras, and then finally to the Starlight Xpress and SBIG cameras.
