Personally, when using camera lenses I prefer a fixed focal length over a zoom lens. With my 294MM I use a 50mm & 100mm for wider field images and an older 300mm F4 L which they no longer sell.
Remember that the 183MC has a smaller sensor than a DSLR/Mirrorless camera so will have a slightly tighter FoV. Also note that manually focusing with a lens can be very difficult - the slightest touch can put you way out. That's why I had Joshua make a focusing aid that allows small movements & holds the focus in place when done:

Thanks Mark, a nice detailed explanation, I have put the setting into Stellarium using the 28-80mm lens and the field of view would get me easily M42 and the Horsehead if my figures are correct....Please see crop..This is what I am hoping....Please correct me if I'm wrong?
