Скачать или смотреть Meade ETX telescope rear photo port - size, thread pitch and adapters

All of the classic Mead ETX telescopes (60,70,80 Refractors, 90,105,125 Maks) use a 1.375" x 24 tpi photo-port.

I've found that the "Meade #64ST T-Adapter Ring 07366 for Film/Digital SLR Camera for Meade ETX-70 and Meade ETX 80" also works on Meade ETX90 and ETX-125 telescopes.

BUT possibly NOT the OBSERVER lines!

You can also 3D print your own 1.25" part adapter using a bike hub to 44mm 6 hole pattern brake rotor mounting piece, see this website:

Of course, somebody has made a 3D model of the thread adapter, but since it only costs $15, I think I'd get the aluminum one instead of trusting my camera to a 3D printed part:

My understanding is that the Celestron NexStar 4e also uses this same photoport thread size/pitch.
