EOS to Evostar 72ED

Hi Guys,

What is the most secure way to connect EOS T5i to Evostar 72ED. The preferred method to direct connect. At this stage, I'm not intending to use the reducer/flattener.
What adaptors would you recommend to purchase?

Thank you

At the very least you will need a T ring adapter to suit the focuser drawtube, but I can say from experience that you will want to have the reducer/flattener in the train as field curvature was obvious even with my 4/3 sensor camera. A UV-IR filter is also a really good idea, for night time use anyway.

The reason why I'm thinking to go prime focus is because of the shortage of Field Flatteners.

I was not aware they were backordered everywhere at the moment. The simplest way would need an adapter to go from a 2" nosepiece to a T ring adapter for the camera.

I cant recall if I needed an extension tube without the reducer but that was with an ASI294 camera which would have less than half the back spacing to the sensor compared to a DLSR. I just sold my ED72 so I can't look any more to work out what adapters I had to use initially.

Found StellaMira 2" Field Flattener from firstlightoptics. $140 AU delivered.
They say it's the same as OVL
