Thanks for the advice it will be a big help. I downloaded Enfuse and was able to test it out a little. It will take some practice but I'm looking forward to capturing some cool scenes. I believe the D5300 will only bracket 3 shots up to 2ev.
You can manually bracket (which we all did before the days of auto-bracketing.) On your camera, set to Aperture Priority mode (A) and use Matrix Exposure mode. Set ISO to 800 or even 1600 (for your D5300, iso 1600 is certainly useable!) Set camera on sturdy tripod.
Shoot one shot at the desired f-stop and shutter speed as set by camera for the aperture you want determined by depth of field desired - that's your 0 ev reference. Now take one at one stop slower shutter speed for the +1ev. Then take another at 2 stops slower shutter speed for the +2ev. Then take one at 1 stop faster than the 0 ev shutter speed - that's your -1 ev and then take the 5th shot at 2 stops faster - that's your -2 ev. Now you have a 5 shot bracket.
eg: Aperture priority (A) at ISO 800 - the camera auto pilot set shutter to 1sec. - that's your 0 ev shot.
+1 ev would be 2 sec
+2 ev would be 4 sec
-1 ev would be 1/2 sec
-2 ev would be 1/4 sec
There's your 5 shot HDR
It's more fun doing it this way - also give you an excuse to buy a really expensive but sturdy tripod!
