i have a jason model 307 explorer 400 telescope. is there a company that sells user manuels and parts for it? thank you. ray
I don't know where you can get a manual for these--they change models and names a lot. I did find a manual for the 311:
But I have an even better bunch of information for you. Here is a website written by a couple of serious telescope makers about how to improve and refine your telescope so that you really do get the most out of it.
And drop me a note if you have any questions about it---it's really good info.
