The sky atlas also provides guidance as to exposure time.
Yep, it's easy to work out the best timings for an individual panel by hand. However, let's say I'm planning a larger mosaic:

* 4x6 panels - each 10x15 degrees,
* 25-30 mins of data per panel,
* shot over two nights in Winter between 9 pm and 3 am, and
* keeping all imaging as close to the meridian wherever possible (i.e. +/- 7.5 degrees).

It would be a pain to work out which panels to take, when, and where...

Anyway, just a thought experiment! I'll stop derailing your thread now
