Photopaper is not nearly sensitive enough... And yes, while processing you should use only dim, RED light, anything else (orange or whatever) contains too much short wavelengths paper is sensitive to... Red perspex is OK, with the 10W incandescent bulb... Maybe red LED are also OK, but I am not sure, never tried them.
If I remember correctly, the sensitivity of photo paper is ~9DIN... or is it 3DIN?
17DIN is 100ASA. Every 3 DIN less is half of the ASA number... That means paper has ~25ASA (or 6 ASA?).
Considering above, I think you have to find film of decent sensitivity if you want to do astro-photography with this camera.
