Precision Octopi Camera Interface's for ASI and QHY.
"Necessity is the mother of invention."
These large CMOS astro camera's coming to market are sure nice but unfortunately some may be a challenge to align orthogonal with the sensor . To make that task simpler, we have designed a precision tilt and back focus adjuster with ultra fine opto-mechanical systems that are used to position the camera in it's proper position in 3d space to allow you to place the camera on the telescope where it should be and can be seen in real time. These units have a typical back focus of about 5.5mm minimum and adjust to about 11mm maximum. There are units available for folks with refractors also and units designed to mount to a filterwheel . Feel free to contact us if you have another need.
From prototype to production. This model can be used on a RASA or a Refractor and a SCT.
A production 4 tab adjuster.
Now available ready to attach to a Baader UFC.
4 tab Tilt/back focus adjuster set up on a Baader UFC for a 11" RASA in the wild photographed by Ron.
A different view with the ASI 094mc pro . Thx Ron for the shots.
Camera interfaces for a QHY600m on a QHY filter wheel and a QHY461 on a FLI filter wheel.
ASI 6200 on a ASI filter wheel. Back focus is 5mm-11mm with a minimum of 5mm back focus and a design of 8mm for centering.
A couple of 30 second untouched other than converting to jpg shots from a RASA 11before and after adding the tilt adjuster. The scope is not perfectly collimated and the back focus distance isn't perfect and no guiding but I can tweak it a bit more by just loosening the push screw a bit and twisting the pull screw just a nudge at any time I get a clear night. (western Washington). You can enlarge them and scroll around for a better view.
