Any help or suggestions would be muchly appreciated..
I don't have a huge budget & would like to cover some good distances with 3 eyepieces if possible.. Thanks

Hi Ricky,
Welcome to IceInSpace
I see you are local to me!
I had a CPC1100 for a few years myself, and it was a nice scope which provided good views.
It is an f/10.
So the strongest magnification you could use would (theoretically) be a 5mm eyepiece.
That would give 560x magnification.
Atmospherics and seeing conditions would rarely be good enough to support that high a magnification. Giving you a very large but blurry blob.
I am pretty sure the eyepiece I used for planetary was a TV Nagler 9mm.
Giving magnification of just over 300x. Even for this, the seeing needed to be good to see datails on Saturn and Jupiter (the only two planets that can show much in the way of detail for that aperture). So you can pick out Mercury Mars Neptune and Uranus, but they are just small disks displaying a small degree of colour. (Sure, Mars occasionally is close enough to spot ice caps and some markings, but is often a disappointment most of the time).
You want to see planets and DSO. But unfortunately they are opposites.
Most DSO's are big, and require less magnification and more wide angle.
They are also generally "faint fuzzies" and therefore an eyepiece that enhances contrast are desirable. With my CPC1100, I found my best DSO eyepiece to be a Televue Panoptic 27mm.
From memory the two previously mentioned eyepieces were recommendations from the knowledgeable staff at Bintel. The third eyepiece they recommended as middle ground was the Televue Nagler 16mm.
That cost me well over $1,000 that day. But these eyepieces have stuck with me and are still my goto eyepieces of quality. Although subsequent Ethos eyepieces I have borrowed were very impressive in that rig.
Hope that helps?
You are welcome to come over and try some of my eyepieces (some as listed in my signature). I also have a 5.2mm ED that you might like to try, just for reference.
Regards
Allan
