Hi!

Well, 400/focal length is a little bit optimistic and will result in most cases in short star trails. A more complex exposure calculator with background explanations can be found here: https://www.lonelyspeck.com/advanced-astrophotography-shutter-time-calculator/

We have had here a discussion about tracking and the tital was like: Will you ever go back after using a tracker and nearly all answers were No

A stacker allows for a much better quality (lower ISO, longer exposure, smaller aperture if required) and there are now affordable and light trackers for any purpose - from UWA to telephoto lens - on the market.

Personally I stack several tracked frames to improve s/n and to remove satellite tracks etc.

I agree with you that 400/focal length is optimistic, 100/focal length is more realistic with a 24 Mp DSLR. but this is for a beginner getting started. Sooner or later he will see the problem, and get a tracker. He will have more issues that elongated stars for the first few attempts without and with a tracker.
