I'm with Jeanette on this one.
I'm also not really into visual so I've looked for something quick to set up and pack up for when time is short (which seems to be most of the time these days) and widefields have become my main source of astro enjoyment.
Even at longer widefield focal lengths(~100-200mm) with a decent portable tracking mount and guiding, I can be set up and running in minutes.
I'm using an Astrotrac which is kinda pricey, but I also looked at the Losmandy Starlapse (which is also pricey with the options) and the iOptron SmartEQ.
I kinda wish I also got the SmartEQ just to satisfy my curiosity on how well(or not) it works. The price really is awesome for what it is.
50 and 100mm focal lengths are great for rich regions like the Sagittarius star fields, Rho Ophiuchi, Orion etc, but, a good sharp well corrected 200mm(prime, no zooms here!) is almost the perfect lens for going wide on pretty much every large nebula, like Eta Carina, Running Chicken, Rho, Blue Horsehead, Witch head, Pleiades, Lagoon/Trifid/IC4685, Orion, Gamma Cyg, North America Neb, even the LMC and SMC. It really is a very versatile length.
