Field Flattener for 14" RC

[Benklerk]

I'm working though my setup half way done now, I'll post the list up later on just encase I have missed something.

I have put down a deposit for a GSO RC 14", will I need a field flattener for a KAF-16803 chip size?

I know you need one for smaller RCs depending on the sensor size, but for a 14" mirror can I get away without the use of one?

The camera has a thread M68 female.

I guess you've searched for a corrected circle diameter and not found one published. I found none, either, when I looked. No marks for GSO on that one! I don't recall anyone posting images from such a scope on here and I found nothing on Astrobin. You might find someone on CN, perhaps?

You may want to investigate the CCDT67 from Astrophysics.

I plan on using this on a F11 Meade 14".

Teleskop Express quote a field diameter of 70mm for their version and 35mm uncorrected.

Well done! I was on their site and couldn't find it. The 16803 has a 52.1mm diagonal so it will certainly need a flattener. I have to say that trying a chip this size in a GSO RC would make me nervous because it is going to have to be in superb collimation and tilt-free to hold up to the edges. However, Harry Page quite rightly called me a wimp in these matters!

The biggest I could find without spending 1000s$ on a flattener is the TSRCFlat3.

Now has anyone used one?

I’m in the same boat but a 12”, did you take the plunge on a flattener?
