Orion 10 inch Dobsonian on Equatorial Platform, and my imaging setup.
As found tonight, using William Optics acrylic Bahtinov mask.
Note the t2-extension tubes required to make the Tele Vue 14mm Radian eyepiece in the finder port of the TS-Optics OAG/flip mirror par-focal with the camera. This number of extension tubes means the eyepiece has to be pulled out slightly but when I tried next size up on one of extension tubes then eyepiece could not obtain par-focality.
Using my enforced time off work to start setting up my Astrophotography setup and hopefully soon I can take my first astrophoto. Sky Watcher equinox pro 80mm with QHY10 single shot camera, and Geoff Dryland’s William Optics 65mm refractor as guide scope and one of those cameras off eBay which Ed recommended as guiding camera. The adapter between camera and WO scope is an XY adapter sold second hand on ebay which should allow me to select guiding star. Hopefully all this will work but of course I don’t know what I am doing!
