I would love to see a picture of your set-up. Sounds expensive!
Also, since I'm new to photography, I'd like to know how you go about a 15 hour exposure. One night? Two nights? Several?

asker v telescope
sony a6300 camera
ZWO asair plus controller
ZWO am5 mount

the mount rotates the scope to allow long exposures
i take multiple 5 minute exposures and use special software to stack them into one image. this is a total of 180 5 minute exposures over 2 nights
