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.

These units are available now.

These are made by me and are semi custom to your application. If you want one, contact me though my e-mail at the bottom of this page for payment options.. Typically it takes a week or less to make and will ship the next week during this Covid mess but the shipping will get faster when this pandemic subsides. Thank you for your patience.
Prices  for standard units  with a Baader UFC are $600 for a basic 3 sets of push-pull screws and $720 for the same with 25um adjustment screws.
$670 for a basic unit with 4 sets of screws and $825 with the 25 um adjusters.

From prototype to production. This model can be used on a RASA or a Refractor and a SCT.

Now available ready to attach to a Baader UFC.

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.
