Astrophotography under the lights

This Questar 3.5 rides as guide scope on a Celeston 9.25, with an Imaging Source firewire camera connected to an old Macbook, running PHD guiding software. It was much darker than the image appears, shot with a Nikon D700 and a 24mm lens at ISO 5000 for 25 seconds. Taken in a light polluted Milwaukee suburb.

I used this setup to shoot the dim planetary nebula M-76.

Hi John, Sorry to take so long. It might be easier to slip an electronic eyepiece into the regular eyepiece port. To go axial, you need some connectors and would be even more. Here is a link to a digital eyepiece. http://www.hayneedle.com/product/ioptronie3000electroniceyepiece.cfm
