Bit of a follow up to the DIY style video posted here a while back, where I machined an adapter to fit a 3.7" TS Optics Focuser to my ES127

Turns out about the only FF that plays well with the TS Optics 3.7" focuser is....

You guessed it... The 3" TSFLAT3 flattener.

So it's back on the lathe to mess around with trying to make another adapter.

Bit of context, After making the 3.7" focuser fit the ES127 I found that using a full frame DSLR resulted in some awful vignetting.

Not surprising since the spacing consisted most of M48 extension tubes with a final reduction to M42 (T2) for the Canon camera.

So...

It's a shoddy video but it gets the point across (i hope)

Enjoy!
