Photos taken with an Autoguider Setup (Parallel Port)

The following photos were taken with the help of a “parallel-port” home-built DIY autoguider using a 4-inch refractor  and a 60 mm guidescope. I have since moved to a setup that uses a GPUSB (instead of a parallel port). I am keeping this list as an archive.
