there is a way to get upto 5 min exposure in bulb. (on the KP anyway)
when in B mode, press the green button and that will allow you to set the exposure time up 5 min.
However, there isnt any software (like NINA, backyardEOS, ASIAIR) that can be used to control image capturing to a computer. so it is not possible to platesolve nor dither
