If you want to have a go at widefields using only your camera and the standard lens have a look at the "barn door concept" if you are handy you can knock one up in an afternoon. I use a very cheap set up for widefields..a $200 guide scope only to get polar aligned and piggy back the camera on a cheap Chinese mount cleaned up a bit. keep your eye out for a second hand eq mount maybe but realise mounts are the game in astro fotos there is no limit on the cash you can throw at one but an eq6 finally is not bad around $2000 after that mm 5,000 6,000 15,000 just say when. Good luck
