XW30 or XW40

Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Thanks for additional comments. It is very useful information for my decision.

I have got a 1-deg FOV in most of my previously own scopes. It has been a hit-or-miss in finding objects. So, I wanted to get a wider FOV to facilitate starhopping.

I have not been sure how wide is wide enough to find objects :) Since I am using an Argo Navis now, I hope that the 1.5 deg FOV (from XW30) is sufficient for digitally-guided starhopping.

I also have the Argo Navis and I usually can get the object within 0.5 degrees comfortably. The AN can actually do modeling of the mount to reduce the errors in the mount and have higher accuracy; although I have not done such modeling due to lack of dark skies and time.

1.5 degrees is good enough to do starhopping; I can find objects with that field with my dob without much of a problem. It would be helpful if you have a Telrad or Quickfinder plus a good star chart to assist you in starhopping. 2 degrees would be easier though but since you already have the AN, I do not think you need to do starhopping..unless you want to have the challenge of finding the object by your own.
