The kits are generally not great and at the focal lengths of 6mm, 8mm, 13mm, 17mm, and 32mm I would say the 13, 17 and 32 will be used the most.
The CPC is nice but a big beastie. We have one and takes 2 to move it safely, 3 people are better.
With the focal length of it a lot of targets will be simply too big to be seen in one go.
At 2800mm a 32 plossl gives 87.5x magnification and a view of 0.6 degrees - that means a lot of objects just will not fit = M42 Orion Nebula, M45 Pleiades and just don't think of M31 Andromeda galaxy. Even a full moon will just squeeze in. And just squeezing in is not I find actually pleasant.
Eyepieces: Really wide is probably the way to go and Wide is the ES 24mm 68 degree. Max of 117x (fractionally under)and a field of 0.58 - odd the plossl comes out as more, makes me wonder if the kit is claiming numbers that do not match the eyepiece?
The scope is not I suggest the best start. It is somewhat specialised and not a general look at most things scope. The narrow field could make alignment difficult although the one here has GPS and once level it is simply center the stars suggested and it all works fine. Mind you it does tend to not suggest some very obvious stars and ones it asks for can be somewhat unknown.
Really the way to go is to fit it out for 2" eyepieces. Trouble it the refiting costs and the eyepieces then also cost. And 2" eyepieces are big, as in B I G!
For a present of a good eyepiece the ES 24mm 68 degree eyepiece is really the option (still puzzled by the field), for 2 get the 16mm or 20mm also. However just one seems sensible at this time. See how brother gets on with the CPC first. Also the 16mm or 20mm makes one an option for the next present.
One of you had better learn about the scope, it is a bit extreme in quite a few aspects. Just answered in a post about 60mm ED refractors, oddly one of those may have been better then a CPC1100 as a first scope.
